    Marantz SR4023 - stuck in standby

    Hi folks.

    I've checked KEY1 at the CPU and voltage is dropping as expected when the front panel button is pressed.

    I'm unclear as to whether voltage should be present or not on P-FAIL in a good state.

    Suggestions on test points for healthy voltage ?

    Relay activates manually when DCPS voltage applies. Where is the standby relay activated from in CPU, WAKE ?

    Thank you.

    Greg.

      TV LED 4K Selecline 65S18 ( T.MS3458.U801) stuck in Standby mode
      by lepak06
      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...

      Hisense LTDN50K220WSEU stuck in standby

      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...

      Onkyo TX-SR507 stuck in standby mode/protection mode, relay clicks one time
      by waterboy1602
      I would be really happy if someone could help me with this problem. I'm already trying for longer then a year with on and offs to fix this problem.

      I have an Onkyo TX- SR507 (schematics added) that is stuck in standby mode. The red light is on if I connect it to the net. When I press the power button I hear a relay clicking. The relay clicks just for one time and then the red light goes back on.

      I had a blown capacitor (C6040)and shorted transistors (Q6050, Q6060) at one channel from the receiver. I replaced R6100, Q6050, Q6060 and C6040. Is there something I missed?...

      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
      Pin1,3,4,5(Vamp),7(Vamp)- 12.6V; Pin2(PWM_DIM)- 0.96v; Pin6(BLU_ON/OFF)- 4.41v; Pin8,9,10- grnd; Pin11,12,13- 5.16v; Pin14(Power ON/OFF)- 3.3v

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