I just got my Performa 5200CD out of storage about 5 hours ago, but when I booted it up, it has no sound, not even the chime. When I plug in headphones to the front of it, or known good external speakers to the back, there is no sound. I clicked on the control strip module for the speaker, and tried it on all values, and even tried changing sound effects and alerts, and nothing, no sound. Other than that, it runs normally. When I opened the back, I did notice there was what looked like a JTAG cable that was unplugged. It looked something like one of these. (modern browser needed) Does anyone know if this can be fixed? Thank you |

@ShinobiKenobi - I embedded your link into the text and added a notice about needing a modern browser for that page. Don't worry! Our the forum has been created so that you could even access it from your very Performa5200CD! Unfortunately, clicking on a link to a modern website might freeze up your Performa, hence we tend to add a "modern browser needed" for those of us on actual System 7 machines browsing the forum. So in the future, if posting a link to a modern page, I'd be splendid if you could just add a "modern browser needed" to help out your System 7 comrades on here  About your issue - has your Performa 5200CD's motherboard been recapped? 1990's SMD capacitors are notorious for getting leaky after 20-30 years. They can, unfortunately, damage chips vital to functions like the sound by doing so. Look for something that looks like "rust" at the legs of the chips on your board. No sound is a typcial syndrome of that. It could be other reasons too, but one way or the other all machines not recapped will die within the next 5-10 years. (with the exception of a few Macs like the Mac SE, but I digress) Just so you know from where I'm coming: I've had the very same issue with my Macintosh IIci. A set of new capacitors later and cleaning the board and the sound came back on. If you haven't recapped your motherboard (and power supply) you really want to. It'll give your dear Performa another two decades (at least) of lifetime Also, could you take a photo of your board and show the connector that's off? I think this would help us. You can use our retro compatible image uploader at revontulet.org for that if you want?

Oh, ok, sorry about that! No, it's not recapped. Wow there are a lot of those SMD caps! I can't even imagine how long it'll take to replace all of them. Luckily I have a lot of soldering experience, so I'm pretty good. But I have bad ADHD, and can't do very much before losing focus. I didn't see any that were leaking, though. The board and all the chips look like they're in great shape. Here's the picture of that cable. I shrunk it down a lot from its original size and made it a small filesize for old computers. http://revontulet.org/2024/03/05/7dbbbab9900a497092b1ce857c66aa65.JPG Thanks for your advice!

I don't know if leaking capacitors look leaky, but perhaps a picture of your Mac's board might yield some clues on your issue? I suspect other's insight into all things motherboard may be able to provide you with stuff that may be happening in that front to your P5200CD, just a thought

Ok, I'll take a picture of it. Is it ok to upload high-res pictures to revontulet, since it's meant for old Macs? Also, I just read an article that said that was the worst Mac ever made, which is sad. It was my aunt and uncle's, which they gave to me a long time ago, but just never had room for it. I always thought it was a really cool, convenient design for the front of it at least. That's too bad about the bad motherboard design. It didn't mention the CD variant, but the one on that page has a CD drive. What's the difference between a 5200 and a 5200CD?

Yes, you can upload a higher res screenshot too. Low End Mac calls the 5200 a Road Apple but you need to understand why. They were coming from a "bang for the buck" perspective - how much computing power do I get for what I invest? The 5200 was limited in that regard. It doesn't mean you can't use it, do fun stuff with it or not enjoy it at all. Quite the opposite. It's still a fully capable Macintosh. I also like the design ... keep yours :-) The difference between a 5200 and a 5200CD is most certainly ..you guessed it ... the CD drive. Your photo of the back of 5200 - the loose cable looks like from a floppy drive or CD drive. Any of them not working properly? I also spot what appears to be "rust" around the ports. Has it been stored in a humid environment? Or is just some gunk and not rust? Hard to tell from the pic. How is the battery on the mainboard? OK? Did you replace it yet? The good news is that the 5200 can be kept alive and even restored to its former glory. It will take some time and a few bucks, but nothing critical. If you're not sure you can do the recapping of the board yourself, there's probably services around where you live. Let us know the country you're living in and we may be able to point you to a store. To give you an idea: I had my IIci mainboard and the power supply recapped here in Germany for about 85 euros and the board was in a bad state and required some "special care". The good news is that after that treatment, your 5200 should give you many many more years of joy :-)
