That means that either the video processor or the power to the plasma panel or the video final is gone. The only way to know it for sure is to take the cover off and testing the parts. Start by checking that both Vs (around 200v) and Va (around 70v) are present at the source, then check that the video final powered and is getting the signal from the processor and finally check everything in between. If you don't know how to do that (or what to do next if one of the voltages isn't there) then call a repairman, there's nothing more you can do to it.

Hello,

is your TV connected to a satellite box/receiver? If yes, check the video wire that connect from the box to the TV.

Or You can connect the TV to a DVD player and observe if there will be any video display. You can as well use another video wire for the connection in order to be sure its not a wire fault.

Also, Check you local stations such as channel 1, 2, 3, 4.... from your TV remote if there is no display, then it means your TV is having picture board fault.

The picture board of your TV might be defective, that's why there is no picture. You might have to replace the picture board of your TV in order for it to display again.

Good luck.

SOURCE: Parts for Maxent 42" Plasma TV

The TV was made by LG. You should be able to google an LG distributor or try ebay. The 953 is readily available but the 917 may be hard to find. Won't be cheap for new ones, around $350-$400 for both unless you can find used.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Cheers,
Stephen

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Maxent 60 in lcd tv flickers


I had the same problem with my 50 inch Maxent, found a solution on the internet that seemed too good to be true, but I replaced a part that cost me $1.38 at Radio Shack and my tv is as good as new. Go to this link for details and even includes pictures. All you need is a scredriver (to remove back cover) and a soldering iron - repair is actually very easy. Good Luck!

Are you sure that its the main A/Vboard coz it sounds like the main power supply issue to me. Anyways the mainboard is the large board usually located at the center of the tv. If you can remove the back cover of the tv and get me a high res picture of the tv I can mark the board for you.

Has sound but no picture


Sorry to say - it sounds like the 'pop of death' - If you got this from costco - give them a call and see if you can claim warranty (or the manufacturer).
