    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...

    Sony KDL-46VL130 curbside rescue has vertical bars and lines
    by Euthymia
    A week ago I spotted a large LCD TV that someone had set out at the curb, and having revived more than one "dead" LCD display by replacing the caps in the switching power supply, I checked it out, saw that the screen looked intact, although it looked as if it had been sitting outside for a few years. There was dirt and cobwebs in the ventilation slots and the RCA connectors were actually rusted, but it had the magic date of 2007 on it, which is right in the cap cootie years so I figured I would take it home and see what happened if I plugged it in.

    It had no problem powering...
