Samsung LCD TV no display only blink (6X) the red indicator light

[Jakk]

Hello Guys I'm new here and I'm not that good in component repair. Please help me, my TV wont turn-ON after we encountered power fluctuation on my area. I already replaced all the capacitors on the power supply unit but still not turn-ON my TV or just blinking the red light (power indicator) only.


Manufacture: Samsung
32 ' LCD TV Series 5
Model: LA32C550J1R

I will post the picture of the Power supply board.

Do you have a multimeter to test the power supply? You can find the service manual HERE near the bottom of the page there is a Get manual in tiny font I will try to attach it as well.

Disconnect the cable between the power supply and the Main board, apply the power to the TV, the backlights should come on and stay on, if it does, the power supply and the Inverter are OK.

Hello Calib and budm, thanks you very much for your time. I already disconnect the cable from Power supply to the mainboard. The backlights turned ON with minimal light (not so bright), is it normal? If in this case the mainboard is the culprit is it possible to repair it? Again thanks a lot for your support.

The backlights stay on, that is good, it means that the main baord is not sending the turn on signals to the power supply board. I never have luck fixing the Samsung main board yet.

Thanks Budm, do you have any idea how much the main board cost?
