75". I think I will probably wait a bit and see because it is not fun to take down. If I do... let me understand... when you say put on it's back do you mean the display facing the ceiling? Sine the back is not flat I think this is a bad idea? Maybe you just mean upright on the stand? Before this I am going to try some wood beams from the floor to bottom of the TV to push up a little and maybe relieve stress on frame and see if any difference. Do you think the middle area being not solid means the middle is pushed in or more likely it is pulled out?
Thanks...

No change. Do those solid colors look normal with the sides appearing more solid? Seems weird to me. Thx.Leave a comment:

Thanks!
Should "Intelligent Mode" be enabled or off? I think ON because you want it to re-learn right?
So far I have these.

Thanks for replying. QN75QN90A. QLED not OLED. I see why you ask though, I wish that was the problem! Let me try DIAH's suggestions....Last edited by nonsub; 12-28-2023, 08:43 PM.Leave a comment:

Samsung QN90A - green blotches
Thanks for any ideas on what can cause this. I thought TCON but images I've seen searching for green tint seem a bit different...the green is not solid on mine.
It SEEMS like sometimes it's better or worse; the attached pics I am not sure if it was just the angle where it doesn't look as bad as the first.
During watching, depending on the scenes the problem is barely noticeable.
I've done the basics like try other sources/cable and factory reset.
Thanks!

Yes before I measured some of these. I notice that ST_BY etc always 7.8V though not 3.5V as diagram but must be some models diff....Leave a comment:

Crazy hey? In all cases boards were last 1 in stock so maybe a bit suspicious.
Can you please provide your address in Germany I can send TV to?...Leave a comment:

Re: LG 70UH6350 (UB.BUSMLJr)
w/e lifted traces SDA at IR PCB = no change, lifted SCL as well = no change. Very tiny legs so I hope you don't ask me to put back SDA and lift only SCL?
Also BTW DRV_ON not actually 0V on exit standby... it is 40mV... I think was always the case....Last edited by nonsub; 02-20-2023, 06:13 PM.Leave a comment:

Oh sorry; you mean eye of tiger
OK please tell me exactly how I test/probe thx....Leave a comment:

Re: LG 70UH6350 (UB.BUSMLJr)
But the eye is working fine... RC standby/standby exit so?
Checked left and right pin of eye and yes 3.5v all the time in both standby and exit standby.
Remember I said on PSU there is a wire bridge labelled FAULT. This is not useful for any test?
thx...Leave a comment:
