      i didnt even know about those, i thought the burned pins where oldered to a pcb!
      what a crap design.

      when it fails again, you have 2 options.
      solder heavy copper wire from the tubes to the invertor board.
      or go led.

              I apply a thin coat of silicone grease on the contacts after cleaning them well, had the same problem with SONY/SAMSUNG inverter boards that use socket set up.

                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...

                sound card dead after graphics card installation
                by paparazzo79
                Hi guys.I own Z690 F Strix board in one of my PCs....everything was working fine with integrated graphics card.I turned off power from it, installed graphics card from another PC, connected all the peripheral cables, optical sound cable of course when everything was switched off.Then I powered on the machine and integrated soundcard is dead.How did this manage to happen and if there is a way to diagnose and replace damaged component?
                The new pci-e soundcard costs here 80 euros which is half of money I spent on motherboard.
                I still can not believe that I am such a looser and don't know...

                Sony XBR-75X950G seems dead with a black screen but backlight and sound is working and no blinking red lights
                by Audeze
                I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

                Does...

                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...

                Dead Sharp Aquos LC-32LE430E
                by borstar_micke
                My 12y old daughters tv (that she got after her grandpa, has sentimental value to her) was just dead without stby light a couple of weeks ago.

                I´ve repaired a couple of computer monitors, classic blown capacitor replacements, a 55" Sammy led with t-connboard replacement and a 42" Panasonic edge led where I replaced the led-strip.

                Not a master with the multimeter, which is cheap and 10-15year old btw...

                So please make it basic...

                To the issue at hand.

                As stated, the tv is totally dead with no standby light....
