Dynex DX-PDP42-09 42 quit working

I have a Dynex DX-PDP42-09 42" plasma TV, abou 13 mo old. In the middle of watching it the screen went black and no sound. Won't respond to on/off switch on remote or the side of the TV. It is getting power - red light is on. Light goes out when I unplug it. What happened? And what needs to be replaced?

Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

LCD tvs come with a florecent tube that projects light through the LCD screen like a stained glass window. It can be replaced if you take it to a repair shop that can order the parts. Given that it works and then turns off would obviously mean the bulb is working, the power is just getting cut to it at some point. This will complicate the repair considerably. I would just replace it, personally. By the time the diagnostic fee and the parts+ labor is done, you might as well just pay a little bit more for a brand new tv with better features and a new warranty.

The T-con also called LCD contoller board needs to be replaced. You can check this link to find the part for your LCD. This board is located in the upper middle part on the screen under a metal shield.
I would suggest to contact them first before order the T-con board.

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .
