    Hisense 50B7100UW no standby but all votages seem to be there

    Hi All

    I have this tv and if I measure the various coils i get 3.3v, 5v, 12v and a 1v.
    But i have no Standby Light and no reaction from the switch.

    If I measure the the pins going to the rx and switch I Get 5v and a few other pins give 3.3v

    Where do I start looking with something like this, could it be the processor. I do feel that its slightly warm. not hot at all.

    Thanks
    Gav

      I have the same TV that also has the same problem, all DC-DC converters have correct voltages but the indicator LED does not light up and the processor starts to heat up just by plugging the power cable into the socket. Has anyone managed to resolve a similar situation?

                  Hisense 50r6- no standby, no power, bad main board?
                  by LemoneyF
                  Hi all

                  I have a Hisense 50r6 that quit suddenly, immediately after turning it on. It no longer shows red a standby light and will not turn on. Completely dead.

                  I have tested the power supply and found the following:

                  363V and 373V across the input caps

                  bri- 0V
                  ana- 0V
                  vamp-17.03V
                  vamp-17.03V
                  stb- 0V
                  12V- 9.3V
                  12V- 9.3V

                  To the extent of my knowledge (...not far!) these numbers are normal for a Hisense power supply in a standby state, though I would like some confirmation that 9v...

                  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...

                  Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                  by tvguy12012012120
                  This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                  Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                  Hi!

                  I have a power supply and on the TV no standby and no power. Have already installed a replacement power supply but the same problem.

                  When I test both power supplies the main capacitors while plugged in, I get 0v.

                  What could be the reason for this?...

                  Hisense 55h8f, standby ok, not turning on
                  by moosets
                  Symptoms: Not turning on after pressing power button on tv. Standby red light on power button turns on when plugged in. Pressing power button on tv causes standby led to turn off for 2 seconds, and then back on red until power is removed (no longer responsive).

                  Tried: Removing power, holding power button, returning power. No change.

                  Power supply: 244194 RSAG7.820.8805/ROH
                  Main board: 244187B, RSAG7.820.8833/ROH

                  Opened back and inspected all boards, no obvious damage anywhere.
                  The power supply is making a slight clicking noise, maybe a...
