Good luck with it. Unfortunately I ordered one of these panels a couple of days ago So I'm hoping you sort it out before I attempt to change mine. Cheers

I see I'll have to try mine again felt sure it worked?

Can't you just connect display directly to 30video thats how I do it?

@shirsch did you ever try the scaler on a plus or 512k as per my previous post #89 about poor quality result?

Did you actually remove the chips you have reflowed? It will be dirty and possibly have track corrosion under them

It sounds like the analogue board is dead from what you have described. Currently have one SE DV with same problem and have replaced the analogue board wit SE 600 mhz one as couldn't find a 700 mhz board

I can see green grunge and dirt. Ultrasonic clean an see what happens. If no go you will need to lift a few chips and see what it's like under them

I had a pb100 that was repaired by an Apple repairer a long time ago and they used a coloured silicon in the holes. I discovered this many years later when working on the pb. The silicon had set and looked like the original covers.

Why not. I still cant get a decent image from the 300A

RP7 quite possible its dead. Can you boot it from floppy?. If so may be scsi chip is dead as well

I'd send it back to Will. Have you tried the original ROM sim? Did you wash in isopropyl after ultrasonic and leave it a couple of days to ensure it was fully dry? Check what pin 7 and 8 on the 68882 do, quiet likely shorting would affect it and other chips

Any recommended suppliers?

Old thread but I have this problem with no boot from 7.5.3 and I have tried the resedit fix to no avail???

Zebra lines is what you get without the ROM sim. Are you sure the sim is OK?

Also check all the pins and the socket for corrosion. I've found even the slightest amount an cause video fail.
