    Technika 21.5" LED 22-248COM (215 189G) Stuck on standby.

    My DVD combi has decided that it doesn't want to come out of standby, I've tried with both the remote and the buttons on the side, switched off and unplugged over night but has made no difference.

    I'm guessing from looking at other threads that it may be a problem with capacitors but I don't know where to start to be brutally honest.

    Good news is I do own a Multimeter thankfully and insulated tools (VDE 1000V) and I know a few people who are very good at soldering.

      I think it may be a UMC Brand, W215-189G–GB-2B-FTCDU-UK as flicking through it's online manual looks exactly the same.

          A good first step would be posting pictures of the boards inside the set so we can see what we're dealing with.

          Note exact symptoms - does power light change colour/state/flash, is this the same as before, did it slowly get worse or just suddenly fail?

              Standby light just stays red, it failed suddenly.

                  Update, it's seems that it may be something to do with charging a PS3 controller off the USB port.

                  Strange thing is that it's been plugged in for at least 2 months.

                      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...

                      Hello to all friends of the forum and well found, here I am asking for your help and sorry for my translated English.



                      As per Hisense tv title LTDN50K220WSEU stuck in standby
                      PSU rsag.820.5687 HLL 4855WF
                      Main rsag 7.820.5842
                      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...

                      LG 32LB1R - stuck in standby mode
                      by lego1234567
                      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...

                      Samsung UA39EH5003R Stuck on standby
                      by Rusenga
                      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:

                      Connector CNM803:
                      TV ON

                      TV OFF
                      Pin1,3,4,5(Vamp),7(Vamp)- 12.6V; Pin2(PWM_DIM)- 0.06v; Pin6(BLU_ON/OFF)-...
