Have TV Questions? Ask a TV Technician
Hello, I'm Shahid and will be happy to assist you. I need additional info to troubleshoot the issue.
- Have you tried to unplug TV and cable box power cords from wall outlet for 10 minutes to reset, replug back in and check?If not yet, can you try it now and reply back with the result?
Sure, please take your time and reply back with the result.
Sorry to hear that, does power indicator light on TV lit or flash when press power button to turn On the TV?
OK, it seems power supply board failure in TV that is why nothing appears on TV (no light, sound or picture) and it needs further troubleshooting inside TV with multimeter to check output volts of power supply board, if standby volts (5V Dc) isn't available then replace power supply board. If standby volts are available then it would be main board failure that will be replaced to resolve the problem. Please check with following board supplier to get identical replacement board for this TV..
