Re: Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
Just to recap my two plans are...
[B]PLAN A:[/B]
Reflow original T-con board to fix the original issue with the horizontal line artifacts
[B]PLAN B:[/B]
Find a way to transfer the calibration data from the Original t-con to the New t-con. Either by copy/pasting the data electronically or physically de-soldering the EMMC and re-soldering it to the new t-con.
For Plan A, I will try to re-flow some of these components. I just need to find a way...

Re: Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
I apologize for taking long to respond. Finding time to work on this was tough this week!

@davi Interesting, I was not able to find VCOM adjustment in the service menus though.
@diah Yes! I was able to get a service remote (I downloaded the android LG Service app, works well). So I tried what you suggested. I installed my replacement T-Con board and upgraded the firmware in attempt to make the t-con and main board have the same versions....

Just tried this. I can take a video if you would like. However pressing into the screen like this had no affect on the artifacts.

Hello!

My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.
(See Attachment 1)

After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I...

Re: New Members - please post your introductions here
Hello!
My background is mechanical engineering and robotics. The robotics side has given me some knowledge of electronics but very far from an expert. I have been trying to fix a tv of mine for the past year and have failed to do so. I have been reading threads on this website over the past few months trying to help me. I am very impressed with the knowledge of the members here. After failing to fix my problem myself I finally decided to create an account so I could post my exact issue in hopes of getting some...
