I've got this westinghouse tx-47f430s and i have no or blue

Customer Question

I've got this westinghouse tx-47f430s and i have no amber or blue LED up fromt, but the standby light on the motherboard is solid and not blinking. Would this indicate a main board failure? I hear the power supply kick on when plugged in and no odd sounds.

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?

Thanks.

Unfortunately, no.
Expert:  Shahid replied 1 year ago.

OK, can you get a multimeter and check 12, 24 and 5V DC output of power supply board?

Customer: replied 1 year ago.
Not at the moment.
Expert:  Shahid replied 1 year ago.

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..
