    Screen testing tool

    Hi guys,
    I'm trying to get equipped with the right tools to repair high def tvs.
    When it comes to testing the screen alone I was recommended to get the LST02 or LST03 here:
    http://www.lcdparts.net/LST.aspx

    They do have a limitation of not able to test larger than 42" screens, if I remember right. Does any one know of a better alternative? And also of something for plasma screen testing?

    Thanks

    For $230 you could just take a spare LCD TV main board and PSU and wire it up to drive a panel. Maybe put it in a case or something.

      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...

      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...

      Samsung UE55JU6800K half screen dark
      by Chrissygizmo
      Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
      I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
