power indicator does not come on atall. Could have had some thunder. I changed the power board but no difference.
TV Technician: Shahid, Technician replied 10 months ago

OK, there are two boards in TV that can be cause of this symptom, either power board or the main board (one where video/ HDMI inputs are located), since power board has already been replaced that didn't work then it is definitely main board (A board) problem that need to be replaced to fix the problem.

It seems old power board is fine and main board of TV is defective that should be replaced. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page so I can get credit of my work on website.
Thank you.
