Re: Won't turn on

Check for voltage at the end of your power cord. If you find voltage there next check for voltage on the other side of your glass type fuse.This will most likely be your problem.

good luck-------------------------tomtaso

TV won't come back after pushing wrong button on remote.

Try unplugging the TV.. After you plug it back in it may be OK. I had a similar problem were I could not turn on the TV (JVC). The owners manual specified in the troubleshooting section to unplug for 1/2 hour. I left it unplugged overnight and the next day plugged it in and it was fine.

if you unplugged it you will only get the no error code 1,2.

Plug back and turn on, when light on power goes out try it again--if power light goes out there will be a error code.

TV won"t stay on turns off in 3 seconds WS 55807

Do the self check when power light goes off.

On front of set press and hold both the menu and input buttons for 5 seconds or longer and release both buttons.

Power light will blink a error code like: 2 blinks, 2 blinks, a pause and repeat about 4 more times.

Let me know what error code you find and I will tell you what it means.

The power board has failed and will need to be repaired or replaced. you can remove this board and, replace individual parts and save a lot of money. You will be inspecting for swollen capacitors and resistors. also, look for discolorations on the board itself.

TV won' turn on

Solder, solder, solder! Shut down circuits protect crts to avoid permanent damage. If any of the deflection circuits are defective, or intermittent, shut down occurs. I have not only seen bad solder on deflection circuits, especially vertical, but also intermittent connections on the yokes themselves. I've also seen shorted convergence ics cause shut down. Don't forget solder connections in the power supply.
