    Panasonic TH-42PX77U

    Help needed to assess horizontal lines on screen. Upon first start up tv only had half of the screen working but after reseating the ribbon cables the most of the screen came back all but the places seen in the photos. Any help is appreciated.
    Thanks

          So I cleaned and reseated the ribbons. Now there are some random thin horizontal lines. Then it just shut off and now red light blinks 7 times. ??

              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...

              Hi all, I’ve got a problem I hope someone can help me fixi.
              I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...

              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,...

              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...

              Hitachi 58HK6100U - Horizontal Lines (Bottom third of the screen)
              by kdaniel
              As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.

              There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.

              After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.

              Left...
