I have a Samsung PS50Q97HD plasma TV that keeps blowing new boards and I don't know why. It came to me with a faulty YSUS that had damaged the VS supply section in the PSU board. I fixed the PSU and fuse and have good VS voltage now. I replaced the YSUS main. I powerd the TV and the upper YDRIVE (Yscan buffer) board chips when pop. I put this down to it getting damaged unseen when the YSUS went faulty. I replaced the YDRIVE upper with new and then the lower board went faulty too (holes blew in t

After reading several forums when my LG 42PC3D died, I went in thinking I had the answer. It would turn on, but then off immediately. The Y-sus board had a blown fuse. I didn't want to risk frying anything else, so I replaced the board rather than just replacing the fuse. When I disconnected the board, it would turn on and stay on. Now, with the new board, it powers up as soon as I plug it in (doesn't actually turn on, just powers up) but won't do anything. The screen is backlit with just

I've a LG 32LC56 that suddenly becomes black screen while i was watching it. Since then, i was never able to get any picture on screen, even the menu picture.
Sometimes, when I switch it on, i see some colored lines on the upper left screen part, but never a menu.
I've replaced the main board by a new one, the problem is still the same.
May i try to change the screendriver board?

I have an insignia 50" plasma ive had for about 2 yrs. There was a solar storm which caused the directv boxes to go out and the tv went out as well ans since then the tv won't power up. In the back of the tv we hear it click 3 times then it turns off by itself and it repeats the on/off process but nothing shows on the screen. I ordered and replaced the power supply board and its doing the same thing with the new board. Please help!

Bought a samsung 42' 4000 series tv, its less than 2 years old & the picture went bad looks worse than a really old tube tv watching an old VHS.
contacted samsung-they don't care, referred me to a tv repair place (75$ to look at it) who said it needs a new sustain board, will cost 300.00
anyone else hear of this problem?
anyway I can do it myself?
where can I get a sustain board?
why is samsung alienating their customers?
Why won't the Samsung Authorised Dealer repair the board? It's not that difficult!There will be a power fault and the picture is not "building" properly. At worst it will be one of the memory chips.With a reflo soldering machine, no probl ...

I HIT THE MENUE BUTTON AND NOTHING. 8 MONTHS OUT OF WARRANTEE. TOOK THE POWER SUPPLY OUT AND NO VISUABLE DAMAGE ON BOARD.

First of all, I'm so sorry you are in this situation. This is a story I'm hearing all too often. Did you have the set on a surge protector? What you are describing sounds like a main board failure but the set will need to be diagnosed to be sure. Pla ...

Samsung PS-42Q96HD Hi
My Samsung PS-42Q96HD went dead one day no pic and no sound- so I opened up the back and on the psu I replaced 2 bulging capacitors.
Now the tv comes on with sound but with no picture. As far as I can tell there is power going through the X and Y boards and the logic board has 2 green led lights on.
Any ideas would be greatly appreciated.
Thanks in advance
Please check whether the inverter is working and giving voltage to the display board. If not, this might require attention of a qualified service technician. ...

My Vizio plasma vp422 made a loud pop and went off. Now it won't come back on. U can turn on and the vizio display turns from orange to white but nothing else. Also u can see the little green light in the back is burning. I have removed the back and don't see any visible damage such as blown capacitors. Also I checked the 4 little white fuses and their is continuity running through them. I don't really know where to start looking next. Would it be one of the boards? Is there any way of checking
You need to get a service manual (good luck) or begin by testing all the marked voltages out of the power supply board at TURN ON.do any come up and instantly go to zero or very low? That is a clue where you would have to follow up. ...

This unit is practically brand new, has no dust nor dings nor damage on the unit anywhere, not even a scratch, but I haven't been able to get the unit to power on. Power cord is connected. The switch on the unit sounds like the others when pressed and everything looks and smells good inside and out! There are no cracks on the circuit boards, no broken wiring no broken or missing or out of place connectors. The fuse is also intact and appears good, but I haven't used a meter yet to check for

Hi Cindy Wells, the Sanyo DP19648 LCD TV failed at 2 yrs and 8mth that I bought for my parents. I can see a faint image with a flashlight and there are no apparent burns on the the board that powers the LCD lights. My question is: If you see the faint screen , as in your fix, should I test the bosrd output as well? Also, I went to inventgeeks.com, he was fixing a monitor is it as easy as he should us? Mom's got a new TV, bought her a toshiba LCD with Visa so I've double here warranty but I hate
IF you can see a faint image it means that the backlight of the tv is not operational, usually due to failed inverter board. Replacing the same should help you resolve this problem. In this particular tv the backlight inverter is part of the power su ...

Hi, I came across one of your posts and had a question. I have a p50hdtv10a, it died, now the screen flickers and turns off. I've noticed that the led on the main board's power input shuts off and then a relay on the power supply clicks and the tv shuts off, the ysus board is clicking while all this goes on, the pattern of the flickering and the clicking on the ysus board are dead on. Which board could cause these symptoms?

I have a sanyo dp46848 46 inch lcd flat screen. It started messing up by half the screen having a dark tint. I was told it was the main board. I ordered one and told them it was a 1AA4B10N21300 with N6EE on the tuner. once I receved the new board and installed it the tv would not even come on, I then noticed the number on the tuner was N6ME. This new board also has a place for a plug the old one dont. could this be why it will not turn on? And yes i can put the old board back in and it will come
