    Digihome 32" LED TV

    Hi all so i picked up this set today, very nice looking set to Digihome 32" LED TV, plugged the set in and nothing happened no lights nothing, no buzzing from psu, nothing my problem is there seem to be no test points i can see or internal fuses. nothing seems to look or smell bad either

      Cannot find a schematic of that PSU. Do you have a part # on the main board? Start by checking voltage across those 400V/450V capacitors on the primary.

            Nothing printed on main board? Not on power board. It looks to be under that yellow sticker.

              as tom suggests test the voltage across one of the 450 v caps there is a fuse a red barrel type by the white power cord connector.

                        OK 340V is fine. Next, see here, check voltage from red points to ground.

                                OK, each of the diodes I pointed out, can you unplug TV and check them on ohms. Any shorted? Hold probes for 5 seconds before reading.

                                  ok checked ohms the top 3 diodes showed 00.0 so these look ok is that right. the bottom diodes seemed to wonder and not settle

                                    Nice! Shorted diode, could be easy fix.

                                    Chop top lead of each diode but in such a way that you can reconnect it with solder.

                                    Then check on meter each diode (you want to test the diode, not the open circuit you've just created!)

                                    Reconnect any diodes not shorted and re-attempt powering set up.

                                    Replace ALL diodes in that section with new ones of same or better type. Do not mix diodes, use all diodes from same batch or tape.

                                      probably gonna have to order new diodes first, will just replace the lot

                                        If you get some sidecutters at the right angle of the lead you can probably cut that there giving you room to probe the diode and resolder it back in for a quick test. You can run TV temporarily (max 5min) with 2/3 diodes.

                                          The PSU works, but shortly after powering on (either in the G5, or by shorting the power-on pin to ground) it begins buzzing loudly. It also makes the LED lights connected to the same circuit flicker. It's definitely a buzzing, not a high pitched whine.

                                          The buzzing seems to come from the high voltage side of the board, perhaps from the white relay. Could the relay be bad, or could the 5V supply be bad enough that it's unable to keep the relay on? Any pointers to help isolate the issue? Thanks!

                                          I have a Sony XBR-65X850E that won't power on, and has no status lights.

                                          Immediately upon plugging in the TV, it tries to power up (before pressing anything). I can tell because after plugging the TV in, the main transformer on the power board begins buzzing, 2 seconds on, 2 seconds off, and it does this exactly 7 times before the TV goes back to an “OFF” state. If I press the power button on the TV, the same cycle repeats. I can confirm that no ‘status' LED's are lighting up when this happens. The backlights also do not turn on, but I can confirm that they at least “light...

                                          The pics are off the other really long thread as they are much clearer than my phone will do.

                                          The fault:

                                          In standby there is no buzzing.
                                          After signal input and turn on, a loud buzzing is emitted from the main transformer, no backlight.

                                          It is because the 24v line is at 21v irrespective of whether the inverter is plugged in. There is a picture on the screen.

                                          If you wait long enough the buzzing stops and the 24v line changes to 24v and the inverter comes on.

                                          I have checked every single cap on the psu and logic board by un-soldering...

                                          Only 3 years old. Owner said backlight went out and burning smell. Didn't bother plugging in to check if had power LED. Just opened the TV rear and found shorted bridge rectifier diode on the backlight circuit on the PSU. SF26G (400V 2A super fast recovery rectifier link ) diode replace with SF26 (what I had on hand) Google AI said G = Green Components.

                                          Burn looked pretty bad on the board but just was blackened carbon coating material. Scraped and cleaned off quite well and clean solder pad for the new diode.
