    Philips 65PUS6121 dead

    Hello
    We have in the workshop this tv that does not turn on. The stanbye either. The psu is 715G6887-P01-006-002M. When connected to the mains I can hear the relay and I have all the voltages in the psu except the ON / OFF. Obviously the main sends the 3.5v of PS ON.
    I can't find the PSU scheme, but it would be interesting to inject voltage into the ON / OFF but I don't know how much.
    Any suggestions?

      Hi,

      Here is a SM for the TV.

              I have been able to find the source scheme in the SM but I am not able to find what voltage to put in the ON / OFF. I am suspecting that the main does not send that voltage, it must be defective. But I'm not sure.

                  In very many cases the voltage is approx. (+) 3V.
                  To make sure it is correct you can cut the power on wire that leads to the motherboard and apply + it to the power.

                      Yes, I have cut the cable that comes from the main, and I have used the 3.5v of the standbye that I have in the PSU, but the voltages remain the same as before. I have noticed that I do not have any voltage in the diode bridge of the primary zone, nor in the electrolytic capacitors.
                      Sorry for my bad english

                          I have changed the main and the TV has turned on correctly.The problem is that I have put a recycled main of a smaller TV and now the double image appears. I have tried to solve it from the service menu but I do not understand this menu. Can someone who knows how to change it help me?

                              Well, I managed to solve the problem. I explain it in case it helps someone. In the service manual I found that this TV has three modes of service. Entering factory mode, the Panel ID option is changed to the corresponding panel that has the TV. This three digit code can be found in the same service manual. Once this value is entered, it turns off and on again and solves the problem. Greetings and thanks to all.

                                  That code is passed on the label behind the TV.

                                      Hey,

                                      I gave up on my last TV and got a new one to try.

                                      Only vertical lines. Sound is OK. Screen is black with a few white lines until I change channel, then these colors gradually starts filling up the screen.

                                      Is this fixable in any way or should I just give up on this one too?...

                                      Hi all,

                                      As the title suggests, how can I be sure that my EC chip is really dead?

                                      I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

                                      Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

                                      Philips 8200 series 65PUS8204/12 stuck at Philips Logo

                                      Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

                                      It does power up when pressing the power button.

                                      I already try the power button while plugin the plug with no result.
                                      Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

                                      Could this be an PSU or eMMC issue ?

                                      PHILIPS 40PFL7007 TV DEAD. D501 testing SHORT on DMM
                                      by vikivng
                                      Hi guys pls can someone help with this set..
                                      Tv doesnt not power on.
                                      No standby light.
                                      There is a burn mark by the leg of D501 diode.
                                      The diode tests short in both directions.
                                      I have been reading this usually means the diode is faulty? As normally would be open.
                                      I have not yet taken voltages since this is obviously short I would like to replace it.
                                      Can someone help me with a substitute for this diode since it seems not to be the standard type?...
