Did you try unplugging the unit for 3-4 hours?

Does this happen in every input?

plasma
Expert:  PramitP replied 5 years ago.

I wish I had a "press-a-button" fix for this. It seems that you'll need to check X and Y sustain boards. You'll also need to check the logic board. Along with that check the SMPS output and the ribbon connections. Usually bad voltage results in defective components and thus in such a failure. If you want to repair it yourself then you should be having proper knowledge about the internal circuitry of the TV.
You should also require a multimeter and soldering equipments and schematics.
If you wish to take it to a repair shop would you like to have an idea of the cost of repair?
If you have any other queries then I would be glad to assist you further.

Regards.

do u think it can be fixed or is the screen shot?

how much do you think it will cost me?

Expert:  PramitP replied 5 years ago.
There is a very small chance of the actual panel to be damaged. If the actual panel is dead then I'd suggest you to get a new TV. If not then repairing would cost you around $350-$500(max) If you have any other queries then I would be glad to assist you further.

Regards.

i have the back of the tv off is there something i could look for?

i noticed there are 3 fuses is there a chance they are blown?

Expert:  PramitP replied 5 years ago.
Most probably no but if the chassis is open then check them. The main fuse must be good for sure. Check the other two.
