    Fault on a Finlux 40F8073-T

    Hi
    New to this Forum, i am looking for some advice please.
    I am trying to repair a Finlux TV for my Mum who is in Self-Isolation.
    The original fault was the Standby Light flashing six times. Online i diagnosed this as a fault with the Power Board. I purchased a tested 2nd hand Power Board from a reputable company, and now i have the Standby Light flashing continously.
    Any advice would be gratefully received.

      Try test number 3 below, try it with both powerboards report results.

          Hi thanks for your reply.
          I am a little unsure how i test the pins. The connector is 20 strand with 10 on 10. There doesn't seem to be any numbering.
          I am a complete novice at this, and i apologise for wasting your time.

              Hello Jason,
              This is where pictures of the TV boards come in handy to help diagnose the problem. Some good sharp images would prove useful. You can add them as attachments using the Go Advanced shown under your post.

                          What is the voltage on each of the diodes when you power up the set.

                                  I can't tell how many wires are on PL500, but check the voltage on each pin that has a wire connected. You will need to have your meter on the pin when you turn the tv on. this is the plug going to the led's in the panel. (pin7 is the side with the arrow)
                                  pin1 =
                                  pin2 =
                                  etc.

                                              Might not be getting the signal from the mainboard to turn on the powerboard.

                                                  Some of the voltages on PL200 are missing. Can you put the voltage readings alongside the connector pin numbers.

                                                                  There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

The protection circuit is kicking in and the standby light is blinking. It goes into protection mode within a second of powering it on.

Looking at the schematics, the permanently enabled power rail called 'unreg sub' provides about 13.5VDC. Where the power comes into the main board on connector CN303, there is a diode...

                                                                  Snagged it up in non-working condition a couple years ago. Previous owner said that sometimes he could get it to come on after repeated tries but other than that he couldn't get it to turn on.

                                                                  Personally I haven't been able to get it to turn on at all. The standby light comes on solid when plugged in, but pressing the power button results in the standby light flashing once every 4 or so seconds. No "click" noises, no light from the panel at all. Just the flashing standby light.

                                                                  No visible...

                                                                  After a while, (sometimes hours, sometimes minutes, sometimes immediately) the tv shuts off. When I approach the TV I notice the standby light is flashing rapidly, but the pulse of each flash is not long enough to notice from afar.

I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                                                                  Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....
