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. - Do you have multimeter and can check volts of power supply board?
OK, can you get a multimeter and check 12, 24 and 5V DC output of power supply board?
OK, power supply board output volts (5,12,24V DC) check is important to determine what board is causing the problem. If you get correct/ stable 5V DC and 12, 24V DC on power supply board then main board would be defective and if these volts are not available (especially 5V DC is low or unstable) then replace power supply board that will help to resolve the problem.
Please contact with following board supplier to see if they can provide you required board or search/ google it to get price and stock info to order it..
