TV Technician: Shahid, Technician replied 11 months ago

OK, we need to do a test on this TV that will help to diagnose the issue.

no
TV Technician: Shahid, Technician replied 11 months ago

OK, it is either power supply or main board failure in TV that is causing the problem, sorry about this news.

Please click following board supplier link to view power supply and main board image and part number info if you have plan to do it yourself..

Main board is most likely defective in TV and should be replaced as first thing to fix the problem.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
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.
