    baird 47 j047

    hi all me again been a wee while

    have this set come to me with a standby light problem
    I cant even measure the voltages as it wont come out of standby

    this is what I get
    5vstb is 2.5v
    +5vsb 5.10v
    +5v 0.6.9v
    everything else 0.0.8v

    anything to look out for with this power board

      Low 5VSB immediately suspect bad capacitors.

          okies ill change them see where we go from there#


          but also tom I know its not the same power board this one takes a mtl199tl

          I tried a working psu in it a mlt198tx from cn42bair I get a green light when I press standby but no screen and no 12 volts etc could this be the bad eeprom on mainboard

          or will this psu not be enough to fire it
          all connectors were marked the same

              does PSON change on good PSU?
              NO - main board
              YES - power board

              These are all basic steps and apply to essentially every LCD and plasma. budm's LCD troubleshooting guide, stickied in this forum, contains such info and others, which I highly suggest you read through.

                  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...

                  LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
                  by ChristianBr01
                  Hello everyone,
                  I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
                  The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
                  What I already found is that the 12.8V are not an the connector to the main board connector to the power...
