The power supply is most likely faulty due to faulty, burned, or overheated internal capacitors. Newer capacitors are made cheaper and due go out.

You can test power coming from power supply leading to main board. It should be about 12-13.5 volts. Anything lower or much higher would indicate faulty power supply

I have a Hisense led tv model F39V77C.


Yeah, replace the set since it appears to be trashed. But if you have a few bucks lying around you might want to try replacing the unit's power supply to see if that resolves the many issues you have.

TV won't turn on. Red standby light blinks


Samsung told me this was a common problem and I would have to have it serviced by an authorized repair facility.
My problem ended up being the internal power supply, but they also told me the main boards burn up.

I have a Sony KDS-R50XBR1 that has no picture. When I turn on the TV, the green Power/Standby LED light blinks for about 30 seconds, then turns red and blinks five times. The Power/Standby LED repeats...


  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.

T.v on standby, red light flashing 3 times, wont switch on


Shutdown with a 3x blink pattern occurs if the 12v from the power supply (GF1 or GF2 depending on model) is lost at CN6153/pin 6 to the AU Board Q1224 to Sub Micro IC1205. The suspects, in order of likelihood, are (1) Power supply and (2) the AU board.

    The standby light should be blinking in a pattern. Count,pause,count... Please post the count and that will indicate the circuit in which a problem was detected. That will allow me to give you details and possible solutions.
