    Even though I don't understand how the main board could cause this type of display issue, I'm going to try disconnecting it and getting a test pattern on the tcon. Depending on the shades of colors in that pattern I may not see the band anyway ๐Ÿ˜’

    It just doesn't make sense that it appears in some shades but not others, particularly in light but not in dark.

        Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed๐Ÿ™
        by Daren87
        Hello everyone,

        I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

        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...

        Lg TCon test pins for screen test
        by alltvrepairs
        Hi,
        i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

        Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

        Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

        Appreciate your help....

        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...
