Repairing Samsung 153V LCD Watch With Dim Screen Difficulty

One of the widespread issues in Samsung 153v LCD Keep track of was show dim. When you get nearer for the screen and begin to observe the show beneath dark atmosphere you actually could see the display but it was rather dim. When you press the front panel button, the on screen screen (OSD) would appeared and this proof the major board, driver board and LCD panel is working and the trouble is within the inverter board. The functionality of inverter board is to generate an ac wave from dc voltage to power up the lamps which was located in the best and bottom with the LCD Keep track of. Should the inverter board has complications it would not light up the lamps and what you might see only a dim show.

I still could recall when I first encountered these problems lengthy time in the past and as a result of absence of data, I couldn’t fix it. I did simply call up my repair friends to asked in regards to the answer but no one able to provide me an solution. Even for those who surf the world wide web for “Samsung 153V LCD Keep track of dim display repair”, you’d not uncover it. As a result of this I’ve to accomplish my own research to discover the remedy and I’ve by no means quit. Winston Churchill as soon as said “Never, never, by no means give up”. I am releasing the answer only to my loyal members or subscribers only-thanks for your support.

Let’s start now! As soon as the cover plus the internal aluminum casing had been opened I observed two bulged filter capacitors in the secondary facet of change mode energy supply. The worth was 470 and 1000 microfarad twenty five volts. I found four more electrolytic capacitors located at the inverter board have changed coloration and also the worth was 47 micro farad twenty five volts. Browsing by way of the whole board with my ESR meter I discovered yet another capacitor faulty (220 uf 25 volts) which was near the fuse (3amp). Considering that this capacitor was situated in the exact same line using the fuse, I presumed that the fuse may possibly give way too. Accurate enough, checking the fuse with an ohmmeter exposed that it’s open circuit.

Now, the real dilemma confronted by a lot of electronic repairers who deals using this product was, right after changing all of the elements above the LCD Observe nonetheless would not work-it’s still dim! Very first you’ve to ask your self why the fuse blown? Could it be caused by the defective capacitors or some thing shorted past the fuse line? The nearest circuit for the fuse was the begin circuit that consisted of the pair of NPN and PNP digital transistor (4k7 +4k7 resistor built in to the transistor). Some other LCD keep track of designed utilized the blend of C945 and A733 in start circuit. Through the way the portion range for Samsung 153V start off circuit transistors were the A6J (PNP digital transistor) along with the A8J (NPN digital transistor) as shown inside the picture.

From time to time only these transistors have challenges (shorted) that caused the fuse to blow but in the previously mentioned situation each digital transistors are tested okay. Given that both transistors had been operating, now the concentration have to be inside the four ic’s that drive the higher voltage transformers simply because the 12 volts voltage was supplying to every of those ic’s. These 4 ic’s have numerous portion figures as well as the most typical 1 that the manufacturer utilized was 4532m. Some board used the AD4E10 and BBD3N13 portion range. At the moment it truly is fairly challenging to obtain the datasheet or technical specification for this range even through the web search.

Do you realize what is within these IC’s? It can be in fact a pair of P-channel as well as a N-channel mosfet built into it. And do you know that it might be examination having a meter? Of course, if you ever utilize the Peak atlas element analyzer, it might prompt for you the consequence. Through the consequence what you get are N channel FET located at pin one (source), pin two (gate), pin 7 & 8 (drain and each pins joint together internally). As for P channel FET, pin 3 (source), pin 4 (gate) and pin 5 & 6 (drain and both pins joint internally). In the over examination I found two of these ic’s have shorted. Changing these two shorted IC using the capacitors and fuse put the LCD Keep track of back to life!

One extra point I would like to share on this model was the inverter PWM IC BIT1305 was quite robust and rarely gave issue.

Challenge in C5707 Transistor in BenQ T705 LCD Keep track

Challenge in C5707 Transistor in BenQ T705 LCD Keep track of

This BenQ T705 LCD Keep track of has a widespread fault of show shutdown immediately after few you “On” for couple of seconds. The trigger in the predicament was often a shorted 1 or two in the C5707 push pull transistors. Apart from the shorted transistor, 1 also has to check the tuning capacitor for huge ESR worth using the support of ESR meter. In the event you don’t own 1, you can utilize the digital capacitance meter to examine the capacitance value. Having said that, from my experience, checking only the capacitance value doesn’t ensure which the capacitor is fantastic unless of course you validate it with ESR meter. The reason why I emphasis on checking this tuning capacitors was simply because the capacitors possess a large failure pace that can trigger the C5707 transistor to go shorted. Additionally you have to observe the significant voltage transformer pins cautiously. I had arrive across really a lot of shorted C5707 transistors due to dry joints in pins of the large voltage transformer.

On this case, as typical soon after I’ve confirmed that only two C5707 transistors shorted, I started to test the tuning capacitors and check the pins of the significant voltage transformer. Both the tuning capacitors discovered to be okay but there were dry joints within the transformer pins. Clean solder was applied for the great voltage transformer pins and I am ready to “On” the LCD Keep an eye on. Guess what? The Keep an eye on has the same symptom once again that is screen shutdown immediately after couple of seconds! I don’t believe it as most of the time it will surely work as this can be a widespread fault!

I started to recheck the surrounding components which have connection to the C5707 transistors but identified no faults in it. Analyzing the board a number of occasions didn’t reveal any improper soldering task. There must be some thing that has gone wrong that had caused the LCD Keep track of to shutdown. Deep in my heart I don’t suspect backlights problem mainly because the C5707 transistors shorted was due to dry joints in the high voltage transformer. Beside, the backlights were fairly reliable for this BenQ LCD Check product.

Thinking back, I bought a brand new badge of C5707 transistors from my electronic suppliers not long in the past. The middle pin (leg) is a bit shorter compared to other two as proven from your photo beneath. I thought to myself would it be this badge of transistors which have difficulty creating the exhibit shutdown following couple of seconds? Of course I can’t blindly suspect the transistors unless I’ve some proof of it. The locating starts………………

Testing the C5707 transistor with an analogue meter set to X 1 and also to X 10 K Ohm does not appear like it’s got predicament. Comparing the outcome with an original C5707 transistor did have some distinction inside the X ten K Ohm range however the studying is acceptable from my ages of encounter in testing transistor. The only thing that I haven’t in contrast will be the Hfe reading. I utilised the famous Peak Atlas elements analyzer to review both transistors and I could obviously see the massive distinction in between the Hfe readings in the two transistors. The initial C5707 transistor has Hfe worth of 379 while the new badge from the C5707 transistor has Hfe worth of 161! At final I found the answer!

I did tried exchange the four C5707 transistors at 1 go with the new badge of transistors however the result was the exact same. Putting in the transistors that have the Hfe reading of 350 to 400 solved the screen shutdown dilemma. This circuit search like it can only work with the identical type of transistor that has the rather precise Hfe worth! That’s why for this type of Monitor circuit, countless technicians hardly can get a suitable replacement. In other words, even for those who could get the substitution transistor which have greater Volt, Amp and Watt but distinct Hfe value, you nonetheless will not be able to provide the LCD Monitor back to everyday life again. From the previously mentioned examination, this Watch circuit has voice out loud and clear that it only require the same component range with the exact same Hfe value unless you’ve some comparable transistor alternative specification that’s identical to the original one.

For my readers which are on this electronic repairing line, although a few of you could not be inside the LCD Watch repair, I wish you might absorb this details and utilize it within your area. Who knows 1 day you would have face the same difficulty that I’m facing and this article could effortlessly enable you to to solve your predicament fast. Have an excellent plus a blessed day!

Plasma Vs LCD Vs LED TVs – What are the

Plasma Vs LCD Vs LED TVs – What are the Differences?

In the last 10 many years, Television technologies has advanced to a great extent and has brought in state of art technologies in supplying the best flat-screen TVs. The most important aspect in the technologies employed has primarily focused close to the size, resolution and compatibility and with this, in the last five to 10 decades there continues to be a gradual change in the option and viewing expectations of individuals.

The manufacturers have now began to put in unique characteristics within their flat-screen Television designs creating the item having a distinctive advantage of full movie impact viewing along with fantastic sound technologies. One can find many types of flat-screen TVs inside the market today, and in order which you could decide amongst Plasma, LCD, along with a LED Tv, you ought to understand a bit in regards to the differences.

Overview of Plasma Television: The show inside a Plasma Television is made up of hundreds of thousands of small plasma cells, and also to put it merely, these cells emit light to make a complete image around the display screen when a exact voltage is applied to them.

Plasma TVs accessible now provide bigger screen size than LCDs. The display sizes of Plasma TVs that are generally obtainable within the marketplace contain, thirty inch, 42 inch, 50 inch and 63 inch versions, though the LCD TVs are restricted to smaller display measurements, which collection from ten inch to 40 inch types. Presently larger display measurements of more than 60 inches are being made obtainable inside the market. 1 favourable level is the fact that, the LCD technology is even more adaptable, which permits vast variety of display dimensions to be created.

Benefits on Plasma TVs:
– Plasma TVs are out there in bigger show screen dimensions.
– Plasma has superior black amounts, and also the contrast ratio.
– Plasma TVs can be viewed from any angle, as long as the viewing angle is amongst 160 to 180 degrees. – Plasma TVs have leading refreshing fee which captures every detail in a quickly action scene.
– Plasma screen can show billions of colors, creating smooth gradations of shades, enhancing the picture top quality to an awesome extent, making the images life-like and reasonable, responding sharply to fast relocating images.

Drawbacks of Plasma TVs:
– Plasma TVS do not carry out as well at higher altitudes.
– Plasma TVs are far more susceptible to burn-in of static pictures.
– Plasma TVS are thicker than LCD TVs and therefore considerably heavier.
– Plasma TVs produce glare in brightly lit rooms though some development in technologies has been made to right this.

Overview of LCD TVs: LCD TVs have Liquid Crystal Displays, a technology which can be observed being used in computer monitors, cell phones, and at times are discovered in camera screens. LCD display was first created for laptop or computer monitors, and now using the application in the technologies in LCD TVs, they appear to become a little far better when you’re enjoying video games on your Tv. However, the choice totally depends upon the consumer, given that some such as the vivid hues in Plasma Television, which comes from its deep black amounts.

LCD panels work with liquid crystal solution being sandwiched among two polarized eyeglasses. When an electrical voltage is applied towards the liquid crystal, the crystals rotate, and this changes the polarization from the light passing by means of them. A LCD panel doesn’t produce light by itself. It just filters or subtracts its back light source to create an picture to the display screen.

Benefits of LCD TVs:
– LCD TVs have better longevity than the Plasma. The regular life-span continues to be predicted as alot more than thirty ages.
– The display of LCD TVs utilizes decrease power in comparison to Plasma TVs, but has a lot more usage than LED. – The display screen dimensions of LCD TVs are offered in different measurements beginning from pc keep track of screens to more than sixty inches.

Down sides of LCD TVs:
– The Tv has a really bad contrast degree and responds slower to fast moving images, making a blur.
– The prices of LCD TVs are greater than the Plasma, and due to the fact with the desire and elevated manufacturing the costs are gradually falling.

Overview of LED TVs: The phrase ‘LED’ stands for Light Emitting Diode. It is an electronic element which emits light whenever a particular voltage possible is applied to its terminals. Although the Tv working with this technologies is call LED Television, but the LED light source is utilised because the TV’s backlight, though the Tv display is really LCD. Although some current Tv styles use CCFL (Cold Cathode Fluorescent Lamps), LED form of backlighting remains a far alot more effective Tv backlight program.

The Positive aspects of LED TVs are as follows:
– With LEDs because the backlighting supply, the TVs possess a far much better dynamic contrast stage than LCD TVs, given that it uses a immediate backlighting technologies.
– LED TVS are ultra thin as significantly as about an inch in thickness.
– The energy consumption of LED TVs are less than the LCD TVs currently readily available.
– Out with the flat display screen TVs readily available in the marketplace currently, LED TVs are considered to be most dependable.

The downside is the fact that LED TVS are higher priced than LCD TVs, but prices are anticipated to arrive down with increased creation.

The above is an attempt to offer a simple conception in regards to the differences in between the 3 technologies readily available presently in flat-screen TVs which would aid a purchaser to choose which Television to purchase.

Mitsubishi LCD Observe Fix – Scratch Repair and Backlight Repair

Mitsubishi LCD Observe Fix – Scratch Repair and Backlight Repair

Mitsubishi Electrical organization from Japan is well-known the globe more than for large-screen display panels and industrial-strength LCD monitors. A few of the well-known types in use right now contain the Mitsubishi LDT461V industrial keep track of along with the MDT461S and MDT402S LCD monitors.

You could notice that all of those monitors are fairly massive in dimensions, ranging from 40-46″. To make a comparison, they are comparable to the measurements popular amongst plasma televisions, but the technology that powers them is pure LCD.

And like any other LCD observe produced in previous two decades, you will discover two challenges that affect even the Mitsubishi watch — (one) Scratched screen, and (two) Dead backlight.

* Given that Mitsubishi LCDs are employed as industrial-grade displays, the front panel is pretty powerful and resistant to scratching. But there is a production distinction in between screens employed in an industrial setup and one put in in properties.
* Inside the latter situation, probabilities of minimal yet visible scratches across the display are pretty great. So the quick correct is to both use a little toothpaste to “fill in” the scratch gaps, or to use a white eraser and vigorously (but gently) rub more than the visible scratches.
* If you are using an eraser, be certain it really is a brand new 1 that has never been utilized before. I’ve tried this scratch repair trick on certain projection TVs and it works great there.
* The 2nd predicament is that of backlight restore. The backlight is often a thin CCFL tube that lights up the watch screen. It can be driven by an inverter board that converts low-voltage DC input to high-voltage AC output.
* A normal backlight bulb lasts anywhere from 3-5 decades prior to it loses portion of its brightness. As time progresses, the whole display screen goes black and you might have no alternative but to replace the backlight.
* Backlight failure is usually a problem that affects all LCD monitors — such as Mitsubishi — although the lifespan will vary according to the way you run it plus the top quality of in-built electronic components.
* The easiest approach to fix a LCD backlight is to get a compatible replacement from Ebay or the manufacturer’s web-site. For essentially the most component, you don’t should purchase a brand new inverter because the current one can be reused.
