Haha ..ok Thank you so much for taking good look. I'm learning.

Thank you SO much. I appreciate it.

yes, for sure sound but I was not aware that bad caps could completely take out video… I was thinking that had more to do with bad UE8 and stuff over on the video side

so what I'm wondering is could failed capacitors cause total video failure? You'd think this thing would have the courtesy to give me a simasimac. if that is the case, I will certainly feel encouraged to recap it.

OK will send more Hi-Rez ones shortly. Thanks.

also, I am testing this on a known, good working analog board and CRT.

just tested an SE 30 board with an issue issue I have not seen before. The board itself looks very clean. I took out the 1989 battery so that might be a clue that nobody has worked on it before. Capacitors show very little signs of leakage and the chips don't look corroded. Now the bad news...

yeah, I have one that fails at verification as well. I wish there was someone who understood the logic behind what part of the drive is not working correctly in order to fail verification.

slight progress ...after letting it sit for a few days, now it tries to initialize any inserted floppy… It goes through the formatting process correctly, but when the head is supposed to come back slowly to verify, it doesn't…it goes to re-verifying and eject the disk with initialization failed...

Hey looks good to me...interesting that the pins you have bodges on are on the opposite side of C7...if C7 was the culprit, I'd expect to see damaged pins on the other side..is that the original UE8 chip or a replacement?

Would a bad UE8 completely take out video altogether or just cause anomolies? I'm gonna be optimistic and put my money on somebody turned the brightness knob all the way down.

Yep looking forward to seeing what kind of mess we hopefully don't have. Sony power supply too.

Excited to have a second SE30 on the way. I went ahead and got this one because - The case looks to be in great shape. It does not "appear" to be battery bombed. You can zoom in on the profile pics and at least see that the chassis by the battery appears to be spotless. The video issue might...

thanks! yeah it's still a mystery but if anything else, I'll keep this one for spare parts. I have replaced the eject gears in all my drives. I know some people recap these. I'm not sure if anybody knows of any failures they could attribute to the capacitors?

no, that was an attempted and failed format

this also may be how it behaves if the top head does not make good contact with the disk… That's my assumption for now as far as the problem

I'm having a specific issue with one of my floppy drives (see attached video). If anybody would know the cause, I would really appreciate the help. Thanks for any insight.

just curious what the consensus is on the quality of those caps. My G4 is not showing any signs of issues, but I haven't looked closely at the caps.

This video explains the reasons why you might want to go with 25v polymer tantalums. I did and they have been perfect.
