Have you tried removing the daughter ram board ? can be anything, including the processor.

I think the small spring is not the issue, but rather the metal plate also acting as a spring, and the chances to getting it lined up is 50%

The idea is to see if removing the upper carrier, the upper head is touching the lower one. If so, something is preventing both to do so.

Remove the upper carrier, maybe this is preventing the head from touching the disk.

Yes i agree, i think i was able to flash a 9500 without any issue, but not the 9250

Yes, was thinking the same thing, poser supply issue first.

yes i agree, the 400k drive has only once head (the lower one) when the 800k drive has two. So when reading a 800k disk you need both. Yes try cleaning the upper head first, if you don’t get any improvement, move the spring of the upper head a notch down.

IIRC it won't work without the right display

If the click is registered, maybe just a bad trace, the chip is probably OK

can be the optoisolator

Hi, hard to say concerning the board, can be the Egret chip. I don’t know for sure, but maybe spotted some bad traces, one seem broken.

Yes, broken peg. was probabaly broken at some point when the drive was stuck and someone tried to remove the disk using brute force.

Hi, not easy to help, but sound is generated by U4 (DFAC) if you have already swapped chips, not your issue here. Moreover, this chip is almost never bad. Probably a bad or broken trace in the capacitor area. Keep in mind that the bad trace can also be located in the other side of the board.

Thanks, yes was thinking the same after looking at the schematics.

No, as said in my post, Analog board was tested ok with another board, issue is in the Logic one.

I have found a cheap SE/30, cleaned the board, new caps around. The board got a chime but I have no vertical sync. I have just a bright line in the middle of the screen. The analog board is not the issue, tested ok. Logic board is the problem. So far, I have tested the continuity from the...

Probably not an issue with the floppy drive, the drive should try to read, not to format unless required by the system. Maybe a bad Swim

Hi, you have to adjust the image with the two tabs present in the yoke side. You will see two cadmium plated tabs next to the coil, most of the time some paint is applied to avoid those rings from turning. Pushing (will make the ring spin) one or another will move the image up or down and left...

I agree with Arbi, but not easy when you only have one unit to play with and no spares to swap

Can be a lot of things, but you can start with basics. Only the bottom row of ram chips is required (the one next the keyboard) for a start. So remove all chips and only keep the better looking ones. Can be a Rom issue also.
