Hello, I have this TV for repair and the symptom is that every black background has a red colour like noise. It is not visible in the menu though. I have removed and cleaned all the flex / cable connected on the boards, nothing changed. Is that main board issue?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Originally posted by Diah View Postits difficult to trace the signal walking thru. need to take a look on the other boards with black cover.
BTW: did the "one connect" socket connected to video processing boards ( the middle one ) via the Yellow socket clip?
The One Connect socket is connected in the main board. The yellow socket connects the main board with the 3-D board if that's what you are asking.

if you did freeze or heating ICs 110-111-112 with no change.. then you have 90% BGA at the big chip.. look on the left side of the Ics where the print line goes.. at this side of the chip need flux and refellowLast edited by Diah; 03-05-2021, 06:13 AM.
