    Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
    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...

    Sony KDL-40V3000 - Vertical lines
    by gpo23
    Hello,

    i order a t-con because i had bad colors on my SONY KDL-40V3000 :




    With the new t-con the color are good but there are vertical lines on all the screen :




    I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

    Is there a way to fix the vertical lines on the new t-con ?

    Thank you for your help

    Sony Trinitron (KV-20FV12) Vertical Deflection Stopped
    by motorahead
    Hi everyone, I've been troubleshooting my 20" Sony Trinitron (KV-20FV12) CRT after it failed to show a picture. The standby LED is blinking 4 times, which according to the service manual is a failed vertical deflection via the self-diagnostic check during power up.

    After getting the TV checked out by a technician and doing research on my own. The most obvious first step was to replace the IC502. I've done so with an exact NOS replacement with no luck. I've read a few suggestions to make sure the 12V supply to pin 2, but that voltage check would seem misleading? It seems if the...

    Sharp LC-70LE650U vertical black and red bars
    by ninja_zx11
    Hi all,

    70" LED TV is Sharp LC-70LE650U.

    Initial problem was horizontal lines and slow motion lurrs on the bottom left of the screen. So I removed both the left and right ribbon cables from the T-con board and tried to clean it with alcohol and when I put it back, this issue appeared. I tried carefully reinserting the ribbon bon cables but same thing. I checked the traces of the ribbon cables with magnifying glass and everything looks good. I cleaned the small jumper ribbon cable on the left side of the screen which cured the horizontal line and slow motion blurs...
