I have A FD Trinitron WEGA. It runs perfectly for the past 8 and half year. Recently, it turns itself off while we are watching. The red light at the TV front is blinking 7 times. I wonder if a repair is needed and how much it will cost, Thanks for your help.
Check if Clock/Timer setting is enabled in the TV. If so, deactivate the Sleep Timer settings.
If the TV is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the TV.
Follow the steps below to perform a power reset:
Turn OFF the TV.
Unplug the TV power cord from the electrical outlet.
Let the TV remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
Turn ON the TV.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Locate the nearest authorized service centers from the below link.
