    Good or bad sound ?

    Hello.

    I have a ASUS Laptop with a GPU problem.
    I took my probes and made this recording.

    Is this normal or is it the sound of a bad GPU ?

      Did you checked the small caps for short. i found crack on a small cap ( two caps )nearby to screw on your video shows. remove it and check for short. You checked this chip also on the video by fourth long testing. Just remove that check.

          Thank you for reply.
          I did some more testing and probing.
          And I located the source coming from a device called, uP1660Q

          https://www.dropbox.com/s/hhqahe578v...1660Q.jpg?dl=0

          Measuring between ground and where the black arrow is, the noise was generated.

          I have ordre a new one, will report the result here

              Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
              by Mgiffune
              I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

              I ordered a supposedly β€˜new' Tcon board this time, and              ...

              EU55JS9000T black screen and sound good
              by totof
              Hello.
              I have this issue on my Samsung EU55JS9000T TV.
              Backlight is good when the one connect box in not connected to the TV and I can launch the TCON screen test with the remote control.

              But when I connect the one connect box the backlight immediatly turn off, the sound is OK (TNT source).
              I dont know if the problem is from the one connect box or from the internal motherboard of the TV.
              I open the one connect box (reference BN96-37087R) and all seems good, simply the Hawk-P CI is very hot after 5 minutes (~65 degres).

              Is someone have experience...

              LG 43UF640V backlight good but black screen and no sound
              by totof
              Good morning.
              I have a problem with my LG Smart 43UF640V TV. It starts, the backlight comes on but nothing is displayed on the screen and there is no sound.
              I thought it was a TCon problem and ran various tests. If I disconnect one or the other of the cables from the tcon to the panel then the screen is white on the side where the cable is disconnected and black on the other side. If the two cables are disconnected the screen is completely black.
              In the 4 configurations I measure exactly the same voltages on the tcon card (model V15 43UHD TM120 Ver0.4) :

              HVDD : 7,28...

              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...

              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...
