Ok, i'm a bit sorry for the rude post, but following certain threads takes so long, too much posts without a single test, i make hard effort to express myself in another language, doing this also when i'm at work, risking accident with the boss..
reading back the posts, you have 11,6v on the tcon input, this sounds a bit low to me, like a stressing dc dc at valley, then the 3 caps at 0,3v, them are also dirty, clean well them and test the whole tv, if 0,3v still there, remove the 3 caps, one of them can be shorted, if you have a good multimeter, NO 5 euro testers, check ohms slowly...Leave a comment:

i suggest to first remove the diodes, test the whole thing, if it works replace them, the other thread is different, i checked , but the diodes behavrd well under a certain load, and bad at anotherLeave a comment:

So i camnot suggest a thing because i have no solution ready, the fact that the masked line do not go to those chip doesn't matter for me, i prefer not to explain why, i surely registered a case where the diode packs produced the intermittent fault at the screen.. i have recall of a recent discussion here.. bye.Leave a comment:

Try searching the method of performing a service reset, the whole tv has been got trough a damaging spike from outlet.. and it's been ruined on some eeproms.. some files on the emmc/nand could have been broken, in that case no other ways but reprogramming it by special tools or direct pc link (too hard to explain)Last edited by Davi.p; 09-19-2025, 11:42 PM.Leave a comment:

This from a video... the test is very poor, not as Samsung service mode, we don't see if is a pre FRC, post FRC and so on..
if only full colors with no graphics then probably are TCON generated, and this is what we need)
Try to cycle "Pattern Type" otpions and show me..

There aren't video tests at all there, in this Samsung is way better... no one had rich menu like Samsung, or there is another menu, try to enter EZ-adjust menu and search for video testLeave a comment:

I do not like your way of participate to this forum, i asked for a picture means obvioisly a clear picture, i already told you what to do on the basis of what you produce (text, photos), if you decide to do something let me know.. otherwise it becomes a very boring discussion.. bye..Leave a comment:

If you haven't knowledge BETTER ASK before doing anything in Service Menu, now show me "13. OLED" menu, we are searching for a "Post FRC test" or the like..
about the pixel refresh as someone call it or Screen calibration is a self running task, i do not remember but i think it is performed after 2 hours of constant TV turn on, i have to check at home some manuals.. or you can search LG oled discussions here last 1 year.. I guess your donor have runned it long to consider it faulty, so do not expect much it will restore itself.. for the few i know.. the SoC test good...Leave a comment:

Hi, you need to perform the screen test to see wether is a main board fault (example ram fault) or tcon fault (again ram fault/emmc fault), try to select 8. Test Option and see what it proposes.. depends on test result you can press down the aboves to see what changes, it can even be the main cpu or tcon cpu.. last of the checks is on the el.capacitors from the power board to the rest, especially tcon..Last edited by Davi.p; 09-15-2025, 06:48 PM.Leave a comment:

To make correct things you could have tried the screen self test / BWRGB test, to ensure the screen is working properly..Leave a comment:
