Hello, My name is XXXXX XXXXX I will be glad to assist you.

How long have you owned the set for?

Also, are there any signs of life currently on the set right now (click sound when power is connected to an outlet, or power button is pressed, etc.)?
Customer: replied 1 year ago.


THE TV IS AT LEASE 5 YEARR OLD AND NO OTHER SIGNS OF LIFE WHEN PLUGGED IN OR BUTTONS PRESSED.

Expert:  Aric replied 1 year ago.
Thank you for the reply Tony.

This problem can be caused by one of several things.

Let's try a hard reboot of the TV. Disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 15 seconds, then release. Plug the set back in and also check to make sure the power cord is secure at the back of the TV. Then press power once. Let me know if you have the same issue.

NO HELP.

Expert:  Aric replied 1 year ago.

This indicates that the power board, in the TV, is not powering up at all. The quick fix is that it could be simply that the fuse is blown. To access the fuse, you will need to remove the screws on the rear of the TV and remove the entire rear panel. The fuses will be located on the board where the power cord connects. Please do not visually inspect these, but rather use a DMM (multi-meter) to test across the fuse for continuity. If one or more is found blown, then replace with one of the same type and rating from your local Hardware store.

If the new fuse does not cure the problem then, there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets. The problem could also be a cracked solder joint, or failed IC regulator, in which case it would be more cost effective to replace the board itself. Average cost to replace the Supply Board is $225 parts and labor on this set.


Unfortunately there is no sequence of buttons or reset you can perform to get the set working again.
