Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems. How long have you owned the set for and when did the problem occur- did the set ever shut down on it's own, were there storms, power outage, etc.?
You're welcome, and offhand- are you saying the TV's never worked since it failed 2 months ago? Also are you looking to try to repair this yourself? If so, it's either the power supply board or one of the sustain boards that's shorted and causing the problem- but some voltage testing inside the set is needed to determine that.
Or are you looking to see what would cause this and what the cost or repairs would be?
I need to sign off for the night- as it's late here. But when we continue, do you have a multi-meter and experience measuring live voltages?
Okay, I had stated above this:
" it's either the power supply board or one of the sustain boards that's shorted and causing the problem- but some voltage testing inside the set is needed to determine that."
So, without a meter we can only go with the best guess which is your power supply board and it can be purchased at the link below:
If you need further assistance let me know. Please do not forget to click the 5 STAR RATING, at the top of the page for my efforts. It is my livelihood and you can follow up at any time if needed.
If you have no experience using a meter to measure live voltages then repairing a TV isn't the best place to start, and learning how to goes beyond the original scope of the question. I will opt out at this point and perhaps another expert will step in.
