TV Repair Questions? Ask a TV Technician for Answers ASAP
The problem started all of a sudden. It's been working fine and now it's having the problem. There weren't any indications that something was going wrong nor any intermittent problems.
Right now, I'm not able to get the TV to come on at all. As I previously stated, it's doing this on a cold set. I left it unplugged for 6 hours, tried to turn it on, and it wouldn't.
Tried the reboot; still doing the same thing.
Thank you for the reply. Unfortunately the problem you're having with the TV indicates a component failure, and not something that can be corrected via any settings or adjustments in the TV.
I will try to explain the possibilities the best I can here.
One common cause of this is the power supply board. There are several capacitors that are prone to going out of spec, and can prevent the TV from powering up. Average cost for this type of repair is going to be $250 parts and labor.
The other common issue is a faulty Mainboard. This board carries the communication to the power supply to allow the supply to deliver it's voltages to the various circuits in the TV, and is around $350 parts and labor in this set.
Also, the backlight inverter boards which are responsible for lighting up the LCD display could be causing this problem. If one of the boards has a short, it can cause the power supply to shut down. Average cost of replacing the Inverters is around $350 parts and labor.
To determine which board in the TV is causing the failure, a Tech would need to measure the outputs of the power supply using a meter to see if any are shorted, or if another fault board is causing it to shut down.
