STOP!

The unit has a fault on its power board and sustain board.

SOURCE: 50 " Phillips Plasma tv. Screen is black, blinking red light.

Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.

SOURCE: I have a Samsung 56"

Actually the Samsung model you have was the first model to come out in 2006 that did not have a color wheel. The LED blinking is actually a self diagnostic program of sorts. Depending on which lights are blinking, and how often, the service manual will tell you where you should start checking or replacing parts and assemblies. I do have most of the codes, so can you tell me if the if the LED light is the only one flashing, how long it flashes, and do any other lights flash at all? Thank you.

SOURCE: Pioneer 65" TV Model # SD-643HD5 won't power up.

I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?

Hisense 50k22dg should i replace led strips first or power board


I would inspect the power board for mushroomed caps and brunt traces. A edge lit led screen has two ribbon cables coming from the power supply, I would unplug one at a time to see if one side lights up. Both led strips rarely go bad at the small time. The problem is most likely in the power supply.

With some models the back light inverter circuit will be an integral part at its power supply circuit. If so the power supply regulator board might need replacement.

If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel
