Pop and screen goes distorted/ partially grey

Your screen has gone bad. the LCD display has it's own IC chips that receive data from the main board and convert it to a visual readout. If you dropped it, there's a possibility that the internal flex cable has partially come loose from the board. However, you can't tell that unless the Nuvi is opened up. You should send it in for repair.

Unfortunately there is a high chance that the sustain board/boards in your TV have failed. Plasma TVs typically have two of the boards, a Ysustain and a Zsustain board. They handle high voltage for the screen buffers and are know to burn out in older plasma TVs. The popping sound is the noise made when the large control ICs on the sustain boards short out. They literally burn up from the inside out. Replacing these boards is possible but not always effective. These boards are expensive and when they burn out they can damage other TV components. In my opinion it is not typically cost effective to fix older plasma sustain board problems unless you can get ahold of the boards at a steep discount. If you are tech savvy (ie you own a multimeter and other testing/soldering equipment) you can verify this your self. However, you should be aware of the dangers of high voltage electronics and have an ESD safe work space. Otherwise you should seek at a repair technician.

This problems only two posibilities,one some how u got a light image burn in into the LCD screen panel itself.If it is the LCD screen burn in,this is not repairable.The other one it could be the T-Con decoders board problems and it dying this board sit wright at middle at the bottom of the LCD screen panel to decodes and regulate pictures as it passing and go in and out of the LCD screen panel itself.Tries websites like Shopjimmmy.com,Ebay.com to buy a refurbish T-Con decoders board for the replacement,possibilites could solved ur light background shadows problems.

When the screen glows grey/white, it means that the T-CON board is bad or it is not getting the 5vdc from the logic board. or loose conection on the T-CON board which is part of the LCD panel assembly.
Does it look like this when it goes out? Checkto see if the 5vdc goes away when it goes out, the 5vdc is supplied through the switched transistor on the logic board..

Go into control panel, properties, advanced, monitor, refresh rate and select display refresh rates that my monitor can display and then choose which one best suites you and your problem.

Those dead resistors that the cause,u are smelling burning plastics.Try website Tvrepairworld.com to buy a whole convergence board for the replacement.The Samsung/Akai are using the same convergence board.

Hi if your tv is a dlp it might be an issue with the DMD board Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

There is a high probability this is the tcon board, located at the back of the LCD controller.

I'll need the exact TV model number in order to be able to tell you what exactly the board number is.

It is not guaranteed - it may be the main board or, even worse, the LCD itself; not many people know, but the LCD dispay has quite some electronics literally inside it or glued to it in a totally unserviceable way.

If that electroncis burns out , the whole LCD goes to trash even if it's physically intact.

It's unfortunate, but not uncommon.

Still in your case replacing the tcon board is the first thing I'd try.

Ah, one more thing - sometims the cables that connect the tcon board to the LCD also burn and cause similar troubles. When replacing the tcon board that will become apparent.

Please rate this answer if it helps.

unless you have repaired circuit board assemblies in the past including replacement of board traces, there is little possibility of home repair here because ".... think i did smell something burning before". Sometimes the manufacturer will include an on-board fuse. You can open the case and look for this, but it may be too late. Fuses may never emit a burning smell even after they "burn", unless it is a slow-type and not encapsulated and you have a keen sense of smell. Sometimes the power section may include large power resistors; large because of the wattage they must dissipate. Look for one of these burnt and replace, but he actual burned part may be hard to find unless you have very good bench-testing tools and instruments. Bottom line is ...highly unlikely, "can i fix it on my own".

Hi all..i had the same problem with my 42 inch LG
rz42px11. its a faulty zsus board(Z sustain part no 6871QZH033A) the pop
sound was the fuse on the board blowing.not that hard to replace but be careful with the connector ribbons! got my replacement from
https://www.chsinteractive.co.uk/ £150....expensive,but probably cheaper than
calling someone out to fix it.
P.S i tried just to replace the fuse on the board T2AH 250v but it blew,i think the fact the fuse blows means the board is faulty..but you could try.
hope this helps someone.
Good Luck
