    Digihome 39180 FHD LED no standby

    hi guys

    original fault no no backlight found 3 shorted led`s which have been replaced now working fine except when i plug in hdmi or scart there is no standby led but if i turn on the tv with out these plugged in tv is all good then i can plug in the hdmi or scart etc
    updated firmware but still no good

    voltages across the psu seem low but are as follows numbered in PSU picture uploaded

    number 1 Diode d504 reading is : 167v
    number 2 capacitor 47uf 200 volts reading is :121.3v
    number 3 set of diodes reading is : 121.3v
    number 4 capacitor 1000uf 16 volts reading is : 11.7v
    number 5 set of three diodes reading is : 11.7v
    number 6 diode D506 reading is : 262v
    number 7 capacitor 47uf 450 volts reading is : 388v
    backlight voltage is also 166v staying steady

    THANKS

      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....

      Vizio D50u-D1 Dead Set No Standby
      by fharris1977
      Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

      Samsung BN44-00259A standby question
      by Crystaleyes
      Hi all.

      I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
      SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.

      Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
      The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

      Yamaha TSX 120 Standby Problem
      by psssst
      Hello forum. I've recently been given a Yamaha TSX 120 DAB radio and ipod dock. Its working well however when put on standby its using 6.3 watts. The manual states less than 1 watt on standby. I measured this with a plug in monitor which seems accurate with other items. In use it uses around 7.5 watts. Firstly has anyone who owns a similar radio also got a plug in monitor to check if this is normal with this unit? In the first half a second the monitor shows 0.3 watts which I suspect is what it should use but something is switching it to be almost fully powered. I've searched the manual for eco...

      JSK4228-050 Power Supply Standby voltage changing! (Possible from Wharfedale LTF37K1)
      by reessi
      Hello,

      I am trying to re-purpose this power supply that I saved years ago from a tv with a cracked screen for a monitor but that is not really that relevent at the moment. I do not recall which tv but a google search looks like it is from Wharfedale LTF37K1.

      You may notice I made some alterations moving some components to the top and some wires which are from a 5v regulator I fitted to the 12v output as the monitor requires 5v. The standby was already at fault from the beginning, it has nothing to do with the alterations...

      Years ago it had some bulging caps...
