Re: LG OLED 55EC930V Horizontal flashing lines problems
Hi , I m in the same problem, OLED55C9 T-CON switch OFF tv between 30-1m30sec so I bought new T-con and the problem is that I got vertical bands
Did you find in the end a way to copy data from old eMMC memory and write to new one?
Thank you...

Re: LG OLED 55EG9100 TCON troubles
Oh, sorry I recorded just to see all the menu settings from the service menu coz like you know the tv turn OFF between 30 sec - 1 min and then to compare with the new T-CON
I do have 3 RC + service RC
I will add new video with Burn Test 5% grey with the old T-CON and a video with my OLED55B8 and the C9 with the old T-con

Re: LG OLED 55EG9100 TCON troubles
Yes you right should try rollinback firmware, I will really appreciate any suggestions how to do it, whenever you got time.
The old T-CON been always with the shield ON to the panel chassis, and I try even without and just the screw , just to see any difference, nothing change still turn OFF , and if you insist to turn on back it's turn off quickly then the first ON … it's coz something getting hot and go in the protective mode I believe...Leave a comment:

Re: LG OLED 55EG9100 TCON troubles
No luck to be flush the NAND the chip looks to sensible to be unsoldered and re soldering
I m still searching what parts from the old T-con made to turn off after few sec probably by any parts getting to hot and then go to protection mode , what about the MOSFET ? Can be the problem?Last edited by Andrei_UK; 12-22-2021, 12:15 PM.Leave a comment:
