My Blizzard.. Oh no... :( help!

I recently had an issue of my A1200 resetting intermittently and the display behaving weird, thinking it may have been a problem with the Capacitors on the main PCB of the Amiga and after changing Monitors, trying different memory on the Blizzard and not being able to find someone to recap it I found another A1200 on Ebay that had been recapped and bought that.

Ran fine for a couple of weeks and the new Amiga is now also resetting.. I thought it may have been the Power Supply so I ordered another that I am still waiting for to arrive.

I then took another look and found THIS on my Blizzard 1230 MkII The component appears to have an obvious leak and even appears cracked for which I would rightly assume is the leakage point.

Now I am assuming this is a Capacitor that has leaked but I am unsure of that component since it doesn't seem to be that common? What are my chances, what can I do and do you guys think this can be salvaged. It's a brilliant board, Accelerators are nigh on impossible to find now and I'd obviously hate to lose it.

That small canister laying against the board is a 32.768 kHz crystal, used by the real time clock for time keeping. The orange residue is traces of rosin flux from when it was soldered in. You could clean the area with a cotton bud and some alcohol to better determine whether or not the part has actually cracked; that shouldn't really happen by itself since it's not a part that gets hot.

In any case, the PSU seems like a more likely source of instability. Don't lose hope just yet

Ahhhh ok.. that sounds like something I like to hear.. you really know your components, I bow to thee I gave the area a clean just then with Isopropyl and to be honest the crack looks more like a slight scratch, looks a hell of a lot worse in photos than with the naked eye/or actual.

Here's hoping it's just the power supply, I had some Ants hanging around too, hope the little bastards didn't crawl into the machine and cause and issue either

I would go after the PS supply.
My a1200 would reset randomly when I added a second disk drive.
I tried my 500 PS and it ran fine.

I can third that. As soon as you start adding things to an Amiga the power supply often cant cope and resetting is an obvious symptom of that.


I had problems exactly the same in the past
