    LG pdp42V6 sound ok no picture...please.

    I have this Lg rt-42px20 (pdp42V6), which got sound but no picture. got it mulfunctioning from a friend.
    Some one already try to fix it, cause the Zsus board FS1 (4A) fuse was blown and replaced with another one (not the original type) the second fuse was also blown. the pdp flat cables (2) connected to the Zsus were pulled out, I guess someone tried checking it..

    I checked the power supply voltages, all fine. attached the flat cables back to Zsus, and put in a new fuse. still got no pic, but the fuse hasn't blown.
    found a post regrading the 15V comming to Zsus - I got 12.3V, except this the Zsus IPM is cool, Ysus is warming up when plug power.
    Another thing, checked voltages on Ysus: Vscw was jumping 111-112-110...should be 120V.

    What I need to do next?

          It depends on the leftovers. My wife's lasagna is very good as a leftover. A TV that someone messed with is seldom worth touching.

          For the OP: These sets have a history of problems due to a failing IPM. The varying voltage also should be investigated.

          For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

          Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

              what i went through dealing with my mobo with dead onboard sound!
              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

              i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

              Grundig Vision 9 37 9880 T USB (Chassis SR) TV Repair Help - Distorted Subwoofer Sound and overall weird sound waveforms
              by LEECH666
              Good day ladies and gentleman!

              I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.

              This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).

              I think the PSU buzzing comes from one of the coils near the bridge rectifier but...

              A funny fuse story – Lumix LX100 II
              by corrize
              Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
              I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
              The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
              There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
              And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

              Marian Trace Alpha sound card repair help
              by Christos Tsiligiannis
              Hello to the forum.

              My name is Christos, I am new to the forum here and i am posting from Greece.

              So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

              To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

              So i tried asking for a schematic from the company and they would not give me one. Instead they...
