SAMSUNG UE65ES8005 with colored horisontal lines

[olegeisler]

Hi All

This huge TV had its mainboard replaced in June 2017 ( HDMI input failed ) - the mainboard was new, not a used replacement from Ebay or similar. Worked great since then.

Now, the owner sent me this picture ( see attachment ).

And of course the TV runs wothout any issues after moving it to my place

Anyone with any clue what the most probable issue could be ?

FYI it is the mainboard. TV started failing after 3-4 hours use, rebooting and displaying the horisontal lines.

FFreeze spray on main processor and the issue goes away.

Another mainboard..............

Check PSU ripple, can be the main culprit..

Thanks - but I already checked PSU, all voltages are corret, and ripple seems OK.
