OLED55B6 - screen goes blank intermittently sound keeps on

[shaileshpandit]

On my OLED55B6 screen goes blank intermittently sound and remote keeps working fine https://youtu.be/paHY_MLtHdQ
This happens while on home screen too. This got worse as time passed by, these days screen just remains on for short period. attached boards and connectors images.

mainboard and power board seems ok as PWR_ON DRV_ON 12VT_ON control signals from MB and 12VT, 12VM, 24VS, 24VD power outputs are working as expected.

Have detached and reattached most of the connecters except PANEL to TCON and LVDS MB side connections, for LVDS MB side, do i have to open the locks from left to right upwords?

Haven't opened TCON heatsink yet, but if i open it what all things i can check? can this be PANEL/TCON/MB issue? also are newer MB like C9 compatible with this TCON? or whole set of C9 MB+TCON+PWR will work with this panel?

Thanks in advance

put the set in service meni IN_START and keep it on it for long time... see if the screen will turn off or not.... search after IN_START IN_STOP how to access at this forum
