Then it may boot up again, but the pic is inverted and upside down. Wait til the next day, turn it on, it boots, after 2 minutes goes white. Cycle starts over. I have reseated chips, pulled the edge connector, redid the rainbow and all 4 ribbon cables, reseated all connections at the power supply, and still have the same issue. Does this sound board related or voltage related? It has the dedicated Popeye PSU, with the open face and the 2 connectors. Anyone seen this happen before?
 
have you tried another power supply? my first mario brothers had a similar issue where it would go white and reset and be fine and then go white again. ended up being the power supply in it... i think that one was a pp7a or pp7b.
 
I'm 100% uneducated in this area but it smells like a board issue. I assume you've checked your voltages already to rule out the PSU, because, hey, you're Phetishboy!
 
This is probably a stretch but I had something similar with my Dr. Mario. Yes, I know, different animal..

But, that game would always boot to a white screen. It was unpredictable. Sometimes it wouldn't, sometimes it would.

So... I took some very light sandpaper and hit the edge connector on the PCB with it. It fixed the issue and I haven't gotten a white screen since. So, just an idea...

But, yours sounds more possessed.
 
How do you test voltages on these ninty PSU's? I've never had to before, as they either put out a steady 5V even, or are totally dead.
 
It's been a while but I thought due to the way the boards and monitors in Nintendos worked the white screen was a sign that the monitor was getting no signal from the board. Could be remembering wrong though. Only part I remember for sure is that when there is no signal to most monitors they either have a solid black or white screen. I think black. Nintendos are the opposite to what the norm is. So if black screen on a standard monitor that is not working with a nintendo board means no signal from the board then white screen on a nintendo means no signal from the board. I think that's correct.

There are test points on the board. That's where I would start after looking at the schematic. They usually aren't labelled with the voltages they should be outputting.

You also can stick your meter on the power supply's pins with no load to see if it is outputting anything.

Well I tried 2 different PSU's in here with no change. Must be the board. Maybe the rainbow cable is bad.
