LG 55EG960V artifact

[Bobby B]

Hi,
Someone gave me that old TV, with few artifacts on the far sides and I didn't mind. However the places of the artifacts are changing when I turn the TV on and off.
Any chance this could be fixable?

this is pixel refresh issue
1- reset after cleaning 2 LVDS and ribbon cables from both side., ( DONT SWAP ribbon cables places or direction )
2- send with service remote IN_STOP

[Bobby B]

Thank you very much for your suggestions
I tried both but they didn't work. I have a new patern that appeared (before I tried anything, so it's not my fault 😅 )

If you have any other idea, I would be very grateful 😃

Thanks for trying to help, but it no longer starts (I only have a little electric noise then it powers down). I broke it trying to clean the ribbons.

Hello,
I changed the ribbons and it's turning on again! The artifacts are still here however.
Here is what I see in the OLED menu, I am not sure if this what you asked for.

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..

use it as its... time to time do Pixel Refresh , you can count how many time it did via e_Z Adj menu

There are 2 options to update some firmware.

There is also a Soc test. It runs 10-15 min, then the tv turns off by herself.
Not a good sign I guess.

It will probably finishes like that. I don't the material or the knowledge to repair a card.

Note that I still haven't found where to do a pixel refresh.

Correction from my previous post : The TV just go to sleep for inactivity. I put some music on the TV to prevent that, and the test will run more than 1 hour without doing anything.

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 is a good news, maybe you'll end buying a less expensive T-con

I took a picture of each menu. I did not see anything that looks like FRC.
I left the TV on for a couple of hours (without any changes) but when I turned it back on, some artefacts had dissappeared and some new ones had appeared. Maybe the pixel refresh was triggered and did something.

we have in this forum same model threats where we solved it, so you have 2 option
1- as my early post #8
2- downgrade the firmware to low version... then upgrade it to last version.., as this set not belong to you... they may changed boards on it.... with this action will be the firmware of MB / MICOM/ and T-CON driver boards same parameter version. search here i did wrote how to downgrade and where to download all LG firmware versions

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 test

[Diah]

i am laughing out , this very easy approve you have never put yours hand on OLED... its digitalis currents. from LG adjusted.. again this is OLED NOT LCD
