Hi my name is Eric,
I hope I can help you with your issue,
You say the red power light is on?
Do you hear a click when the TV is first plugged in?
Are you wanting to get an idea what a repairman will charge or did you want to open the TV yourself and attempt to fix it?
If you need more assistance,please tell me your technical ability,
1 I can solder and check voltages and want to know what board/part is bad so I can fix it myself
2 I am pretty good at figuring things out, but do not want to open the Tv up
3 I just know how to turn on my TV
This way, I can help you without getting to technical unless needed.
If I have helped you with your issue please click accept.
If you have more questions you can still respond until this post expires,
I will reply asap
