    LG 50PA6500 power supply Relais klicks

    Hello guys,

    I got the broken plasma LG from ma friend to take a look at.

    The tv cant start. If i plug in the cable i can hear the relais klicking several times. It tries to start and klicks again after a few seconds. No picture.

    Removed the above right connector. Still the same error.
    I found out, that its a power supply Problem.

    I measured a few things with the multimeter. Did also a few tests with m_on and rl_on connected to the stby pins like described here.

    http://tomtechtodrepair.blogspot.de/...d-diy.html?m=1

    I cant measure the 190v or more. I can hear one relais clicking. After moving the m_on switch, i hear the other relais, but no Output on vs. And then the same thing starts as described above. One relais starts to klick and after a few seconds the other. Again and again.

    Couldnt recognize any bad capacitors. Fuses are good, Running out of ideas.

    This is the power supply

          Thank you! This was the solution. Got one from a local store. It has a bigger size, but i could connect it with some cables. Working well now.

          3,49€ repair costs Couldnt be better

              Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
              by sam_sam_sam
              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

              Modification to a ZD-987 desoldering/soldering station using a external switching power supply
              by sam_sam_sam
              I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

              I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
              by shamsudeen
              Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
              I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

              i know that in linear power supply the noise will be very low comparing to SMPS supply....

              Russound CA4 Power Supply Repair
              by CMCM
              Hello Everybody,

              Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

              Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

              The outputs marked 12v and 20v are all measuring only 1v.

              The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

              The capacitors physically look clean (no bludgesor leaks) and...
