    55” Micromax Led TV Half screen red

    Hi
    My tv ( Micromac MM-5517 ) 55” half screen has vertical red lines when there is no display on the screen as you can see from the attached photos.
    I tried replacing the ribbon cables from tcon to panel but nothing was changed. Any suggestions please?

                      The half screen affected must either be from output (tcon) or input to screen on that side (long thin board bonded to screen). If that board is at bottom of screen bad bonding connection could also be the cause. Check small caps on that board. A tcon replace may be worthwhile??

                          No good pictures, take some new ones with the whole screen and a input source, it seems cracked screen to me..

                              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...

                              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen

                              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...

                              LG 55UH6150- trouble powering up, then half lit screen (pictures!)
                              by valvashon
                              The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
                              Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...

                              TD Systems K50DLG12US half black and half white screen
                              by Raulnn
                              good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?

                              By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...

                              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...
