Hello,
I'm trying to repair this revolution x board. At the beginning it was booting with check errors on u49 and u67 and u77. I successed to fix those errors replacing all the smd capacitors, u57 and u58, repairing a corroded trace under u17 from u28 pin 7 to u17 pin9.
The board booted fine and everything looked to be working but...
after a while the screen gets garbed so there must be something that fails after a while, Tried both with fresh and hot air on every component but didn't find the culprit.
Any idea?

first start video: everything works fine

after a while screen corrupts
