    LG 32LD320 5v standby only - Fixed

    Thought I'd post a solution to this LG I fixed today, maybe it will help someone out.

    On turning on the power the standby LED would just flash. No voltages found apart from 5v standby.

    Poked about on the mainboard and found 5v on the input of IC801 a SOT223 marked 17-33. Figured this was a 3.3v voltage regulator but I was only measuring 80mv on the output. Pulled it off and find a short between the output and ground. I pulled a couple of the surrounding ceramic caps but it still remained. After a gentle nudge from Th3_uN1Qu3, I injected 3.3v using my power supply and found C2025 toasty hot.

    Pulled the cap and the TV powered straight up. Replaced with a 1uf 10v.
    The TV has been on all afternoon, fixed

                  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....

                  Sony KDL-40EX403 Stuck on Standby Fixed
                  by Ukdigger
                  This TV was stuck on standby, all the voltages tested ok. I Googled the problem
                  and found that the ambient sensor could be causing the problem. I disconnected the two leads going to the ambient sensor (on the infra red remote sensor board) and the TV worked with no problems.

                  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...
