    Goodmans Ld3755hD Stuck in standby

    PSU doesn't seem to have a model number on but from googling I think it is this

    17pw15-8

    I've seen repair kits for this but have then seen a few posts stating it's a eeprom fault.

    I've also looked through the repair kit references i've found them all on the board apart from IC829

    cheaper to go for the repair kit?

      i'm guessing ic829 isn't present on this board as i've looked and looked

      sourced all parts from cpc apart from the voltage regulator

      anyone help, it's 78l06 wfg 2j

      nvm misread it's 78l05

          rather than orderin parts on a whim, try to determine exactly whats wrong, are there any swollen capacitors?

              Replace blue capacitor C878 (15nF/630V)

                  For a stuck in standby fault, you need to check the power ON OFF pin to see if it is turning on. If it is, then you need to find out why power board is not starting. If it is not it is a main board fault. Also check the 5V and 3.3V standby output. This is standard procedure, do it for all power boards.

                  99% of these are power board faults due to the bad 15nF capacitors in primary. C878 and C877 should both be replaced. However there are many other faults these have and that is not a guaranteed fix.

                      wasn't exactly a whim, plenty of threads and kits on this problem, as the psu isn't labelled and neither are the connectors at the time I didn't have access to a SCH to check so for me to order the parts for less than £3 from cpc isn't a big loss if it doesn't work

                      but as above seems tom and another thinks it is as stated

                                      I have a feeling the -9 and -8 will work but they need a different cabling loom as the connectors are different.

                                          ye seen that, stupidly took off a point when desoldering caps, too hot a iron

                                          got another for £20 so all sorted now

                                              Hello

                                              I have an TV Led 4K Selecline 65s18 with mainboard T.MS3458.U801

                                              The TV is faulty with stuck in Standby RED LED. Can't power the TV.

                                              Before this problem , the TV stuck the picture with artefact , i unplug the AC cable and since the tv is stuck in standby .

                                              All voltage are OK on PSU and main board for regulator. I tried flash firmware 25Q64 with many dumps

                                              But the voltage on power button is 0.6V not 3.3V. When i press power button the voltage up to 0V. I tried to add 5V with Power Supply on 5V_STB and 3.3V on Power...

                                              As per Hisense tv title LTDN50K220WSEU stuck in standby

                                              I enclose the psu diagram, after the first routine checks I find myself with a regular standby voltage of 3.3v blue light on steady when the power button is pressed nothing happens, psu disassembled and bench checked ... forced ignition by sending a signal 3 , 3v on the SW and PWM2 pins the psu turns on and delivers all the voltages...

                                              Hi. I have the following problem with my TV. After connecting to mains, the standby led (red) turns on, but TV is not responding to remote control or buttons on TV. After some measurements, I found out that +5 V standby voltage is present, but I dont have ON/OFF signal coming in to turn PSU on. It stays at zero volts. After looking at the schematic of the mainboard, I should get ON/OFF signal coming in at the R1402 resistor, but it stays around +3,5 V. So I removed it and I was able to turn on TV with buttons on TV, but not with remote control.

                                              What could be the problem ? Thanks...

                                              Hi techs, I have a Samsung ua39eh5003r which switches on and then goes to standby. I have to wait for a day or two for the tv to switch on again, all the time it is stuck on standby. I have checked the voltages on the power supply board on both occasions when it is on and off and these are my findings:
