Hi Manitoban
The defect in the panel triggers a safty shutdown, it does not stay on longer then 5 min.
I charge a $50 diagnostic fee.
2 out of a 100 customers want there unfix-able (panel issue/parts do not exist)or (too costly to repair) TV back.Leave a comment:

Re: LG OLED65B7P-U thin horizontal black line
new t con did not fix the horizontal line. Bad panel it is. The TV is going to scrap. Anyone want to buy boards?Leave a comment:

Re: LG OLED65B7P-U thin horizontal black line
no i did not do such tests. The line is there before anything gets hot, right of the start. I use freeze spray to find components shorting to ground and if a devices's performance deteriorates over time as it is operating....Leave a comment:

Re: LG OLED65B7P-U thin horizontal black line
In this low light picture, you can see the line. It is there in normal mode too. So you say, it is a (not completed signal or not strong enough signal), that gives this TV an unfinished line.
That sounds better then a COF or banding issue.
Could it also be, that the main board sends an incomplete signal? instead of the t con?
Danke

Re: LG OLED65B7P-U thin horizontal black line
I remember the screen stayed cold to the touch
even after turning it on repeatedly
i will test for heat, around the black line if it is shorted...Leave a comment:

Re: LG OLED65B7P-U thin horizontal black line
Thank you for the feedback
bad panel driver/tabs or bad adhesion of COF; they are hidden behind an aluminum cover and i would have to dremel the back open to access them.
I will try adding some pressure on the visible conections
if that wont work i will see if the customer lets me disect his expensive piece of garbo
so t con and mainboard are out of question then

LG OLED65B7P-U thin horizontal black line
I unlocked the tv with a service remote. I can see a thin black line(see attached picture)
i can keep the tv on from 20 sec to 4 min, depending on how much image is being displayed.
high rez images make the tv shut of instantly.
i can play a dvd for a min
that line is on top every image, osd, dvd, menus, factory menus
the line starts on the left side, 8 inches in and ends about 1 inch from the right side
it is not locking up after 5 shut offs
all voltages are good till it turns off

Replace Backlight 6V LED with a resistor, diode or jumperwire
Can i replace my TV Backlight led 6v with a resistor, diode or jumperwire or 2 3V led in parallel?

Yes i know, I might get a dark spot on my tv.

Re: Samsung SyncMaster T2600HD is dimming
Read "4Troubleshooting.pdf" in "https://www.badcaps.net/forum/showpost.php?p=677215&postcount=12" to id which board causes the issue.
Mainboard was my issue. Ordered the last one that is out there in world wide web. Also ordered the "SEMS10 IC"(Big main Processor 280+ legs). Will attempt to fix the old board. PM me if need a mainboard.Leave a comment:
