Parts machine; have a Cutting Edge external drive and plugged the internal cable in off 1 pin; now no screen, no beep.

Yes...after removing the double sided tape on the analog board, there were a couple of broken solder joints at J1; so after reflowing, I am back to the smiley postage stamp pictured, it seems to boot based on disk drive activity but the screen remains as pictured . The screen looks about right...

Awesome thread. After looking at your recaps, rest assured, I will never be posting a picture of my recaps. Looks great.

Speaking of caps......power supply of same IIsi

Sorry if this is obvious or posted somewhere else, but I have a Macintosh plus that chimes and then HAD a small postage stamp with smiley face and no error code. After a few off and on's, it now has a thin line the width of a postage stamp in the center of the screen. It still chimes and I...

That combination worked well. Switch 7 on the one I have is broken, I believe in the off position. Right now resigned to using this SI with the BMOW ROM and move onto the power supply recap.

That was disappointing. Removed and replaced caps with electrolytics. Same behavior: white/grey screen with internal ROM, works with BMOW ROM.

Working but not as designed. Big MAYBE someone might know how to interpret this behavior. Initially, when using just like my other IIsi, no chime, no video, LED on, internal HD spins up initially but then stops. Eventually got video adapter with switches and found a video output white or grey...

Cannot remember how I ended up with this board (one of 3 nonworking SI boards I've collected over the years) but it is nonworking (no chime, no video) and has been recapped. Whenever I think of replacement by tantalum capacitors, I am looking for a positive and a negative. Are these bipolar...

It didn’t look bad. Will have another look at some point, was just determined to get an accelerator board working so sacrificing one SE ok for now.

Took another SE apart, the problem is on the analog board…..I’m guessing fly back as I hear a very quiet clicking

It was the analog board...not the power supply.

My SE recently just crashed, no screen, no noises, no bong, no disk drive. I thought power supply and wanted to get inside to look at the boards anyway so just thought I'd remove the power supply to check directly. The Sony Model CR-44 power supply has a sticker on the side with pins and...

While I was in here, this is the SE Mainboard with the accelerated on top with the plugin for the video card.
