    Faded screen and crashed on Panasonic P55VT30

    Hello everyone,
    So I need help with my Panasonic P55VT30 flat screen. I actually found this bute being thrown away, so I wanted to see if I could get it working.
    The TV looks to be in mint condition, but when I first plugged it in, it would power on with no backlight or screen. I opened her up and found that the (from what i understood to be) SC board what completely disconnected. I plugged that in, and the screen actually turned on, although everything seemed to look washed out and colored over. If I actually press the menu/internet/viera tools buttons on the remote, the tv crashes, and gives me eight blinks.
    I've tried to reseat just about every ribbon cable, to no avail. This problem seems really strange considering most people with the eight blink error can't even get the screen to come on.

    I did notice that there were some empty ports on 2 of the boards, making me think they could have been replaced. Thanks for reading through this, also sorry for the low quality pictures.

    Maybe check that the earthing pads on the sc,ss and the contact points are clean. then make sure every bolt is in and firm on those 2 boards.
    This series seems to have issues with the screws working loose and arcing. often the Sc will blow but I have found screws on the SS loose so worth a go.

      I checked and cleaned every contact point on both boards, and doubled checked that every bolt is tight. I took off the sc board and noticed what looked like tea or juice on the bottom of it. I'm guessing this board is to blame.

        Another update, I was fiddling around with components on the sc board, and I actually got it to work in every way. Except the screen is still staticy, and I get a giant yellow bar on one side when I'm on hdmi.

          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
          by Ryan.man
          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

          Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
          by Alicat
          Hello,

          Stopped by this site trying to fix my parents Panasonic Plasma TV.

          Model number is TH-50PZ85U

          Power comes on and the red power light stays on solid.

          Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

          I also hear a few clicks.

          I also think my parents said there was a thunderstorm and the TV failed after that.

          Section 6 in the service manual talks about power and no screen,...

          Macbook Air M2 A2681 Kernel panics after screen replacement
          by reformatt
          Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

          It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

          iphone XS turns off when press on screen.
          by smic717394
          Hi,

          I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...
