That's good to know. I ordered the caps. I just have to find the time to solder them in.

The best thing to do is just clip the leads, exacto knife or dremel. Pull the casing off, then you can unsolder each reaming lead individually.

No dice. Not the ROM. Same behavior after being reseated.

That pops sounds like a cap. Although caps don't just pop without reason. Too much voltage and you'll pop it. Which means something most likely went causing the cap to be overcharged.

Ooh, that's nice. A coworker of mine gave me a bunch of those mics a few years ago, but I didn't get any of the little mounts with them. You should hold on to that.

Hum. No. I'll have to try that when I get home.

Cool. Thanks.

Yes, I'm definitely interested in seeing this work too.

@macdrone. It could have very well been damaged in shipping. The box was trashed when I got it.

Here's an update. Macdrone sent me a new analog board. He tested it in his machine and it boots. Unfortunately, it doesn't work in mine. It's actually worse. I was able to eliminate the horizontal lines by adjusting the brightness knob, but the display is seriously warped and there's a lot...

I might just keep all the spare parts as backup. Most of it's dead. The only thing left from the 575 is the CD-ROM drive. The case is in bad shape. As soon as I touched the front bezel, it just fell off. Most of the clips that hold it in are broken. Same as the back I/O panel, one of the clips...

Thanks. There's a whole writeup and walkthrough on my hobby site if you want to check it out: http://appletothecore.me/files/mac_tv_restoration.php

I got the Performa 575 parts moved into the Macintosh TV and it's up and running. I used the Performa 575 as a test bed for the Mac TV analog/logic and the LC 520 analog/logic, as well as the extra analog board that I bought. As it turns out: - the Mac TV analog and logic boards are both...

Thanks. I'm definitely going to take some measurements this weekend and see what's what.

Here it is. Pretty filthy, but it works. It was pretty dusty inside. I can't wait to take it apart and test my other boards. I plan on taking a bunch of measurements on the good analog board and then compare them to the Mac TV and 525 boards. Maybe I'll be able to identify the point of...

Got the 575 in the mail last night. I opened it up and cleaned out the dust bunnies. I had a look a the analog and logic boards. Everything looks good. No leaky caps. I plugged it in and fired it up. Works like a charm. Hopefully this week I'll have time to use it as a test bed for the boards...

I'd much rather have a working Macintosh TV than a working 575 even if the guts are the same. It's all about the black enclosure! True, the Macintosh TV used a "modified" 575 board, but I'm not going to actually watch TV on it. On the bright side, I also have a 520 that doesn't boot that also...

Don't forget, it you connect your hdd directly to the chip, plugging in anything to the actual SCSI port will probably screw up your termination.

Yeah, I saw that trick in another thread. This doesn't fix itself once it's been on for a while.

I know it would be a sin to hack the back up, so maybe you can somehow sneak a SCSI cable from the internal drive out the back and into the SCSI connector. Maybe somehow sneak the cable out the security lock hole thing. You might have to come up with some sort of homebrew cable.
