Hello ArcadePeeps,

Any ideas of what's going on with my Tron Arcade Stand Up? Turn it on and see a bland white screen or mixture of white and black "Tetris Blocks"

So far:
Replaced with Suzo Happ Switching PS
Cleaned and checked fuses/Continuity
Checked Voltage on Power Supply (5.023)

Next?  Anybody seen this before?(https://twitter.com/MachoArcade/status/1269796173474226176/photo/1)
