    Viewsonic N2635W freezing

    I acquired a Viewsonic LCD TV model N2635W.
    The unit works fine for a several minutes and it freezes.
    And later on it restarts but without the sound.

    after turning of the unit for a 5 to 10 minutes , the unit powers on and after freezes again.

    any body has similar issue?

    Thanks

    Sounds like its overheating. Point a big old box fan or something at it and see if it stays on longer?

      Thanks for the suggestion. I put a fan on the back of the LCD.. and the TV has been running for 5 hours now without single freezing. .
      The fan seems cooling the LCD and preventing the overheating.
      Is there any faulty component inside that causes overheating..
      I am thinking of installing a small fan inside the TV.

      thanks again

        Try checking (carefully) inside for the thermally sensitive component. A small cooling fan, a heat sink might do the job, or it is even possible a thermal transfer pad may have been omitted.

          I dont suggest messing around/feeling aroun for hot components. You kight get shocked or the tv could get damaged. Just add a small fan somewhere inside...

          Ps: lol i was right! Not bad for my first time answered a tv questiom

            usually the solder balls break on the CPU BGA and causes just this. you can heatsink the main CPU and put a fan on it, or reflow the BGA with a heatgun controllably.

              Repair of an LG split AC system indoor unit PCB
              by ngml
              I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
              This indicates an error in the communication between the outdoor and the indoor unit.
              The outdoor unit is fine, so the problem is the indoor PCB.
              The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
              I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.

              Does anybody have the schematics of this board,...

              Dell Inspiron 7520 (Intel/AMD) LA-8241P Freezing Issue
              by FShahid
              Hi I have Dell 7520 which has i7-3632QM as well as AMD 7730M Discrete Switchable GPU.

              This is BACO Switchable meaning the AMD GPU can only "render" and cannot work as alone as it depends on iGPU for output.

              Attached is the datasheet for LA-8241P which shares common with Inspiron 5520 and Vostro 3560. Link to Schematics: https://cdn.badcaps-static.com/pdfs/...a856347d78.pdf

              The laptop has worked flawlessly for last 9 years, with CPU temps never exceeding 90*C and GPU barely reaching 80*C on gaming/full load.

              Since...

              Bose Companion 5 - Unit Powers On then Cuts Off Shortly After
              by nobbnobb1
              Hi guys,

              Trying to salvage a Bose Companion 5 computer speaker system that powers off shortly after powering on. It's got a primary USB input (built in DAC) and an aux 3.5mm input. The USB appears to be the primarily source that tells the unit to power on (control pod LED goes green) as the unit has no power switch.

              When I first connect power to the unit, plug in the USB, it will play audio nicely for a minute before it drops out and the unit appears to go into standby (control pod LED goes red). It stays in standby and I cannot seem to power it back on without physically...

              Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
              by lostone
              Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

              First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
              When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...
