Dead Blizzard 1260?
« on: April 08, 2010, 01:25:04 AM »
Hello:
When I put the Blizzard on I only get a black screen. No light at all.
No "ticking" on the floppy drive, and only the internal cd rom starting.
If I put a Hawk ramboard the Amiga 1200 works fine.
Have tried changing the memory simm to another, and without it too.
The PSU is the A500 one.
How do I know if its broken and what can I d:( ?

It came with two oscillators with sockets at the accelerator to change them, and I have tried both, 050 and 060 (a couple of minutes without fan, only to try it), and nothing.
The Blizzard worked with the Worbench 3.0 (I have two HD, a 450 mb one installed with 3.0, and a Fc with 4GB and 3.1), but had guru page with the 3.1 and I didn't had the floppy working to put the software.
I don't remember if I got it working with the 3.0 kickstarts or with the 3.1 I changed.
Now I have the floppy drive and everything working (with the Hawk), and the library installed.
While I was waiting for the floppy I cleaned the contacts and the whole accelerator with Isopropyl Alcohol (perhaps too much could damage it?) . Too I changed the battery (soldered) with the same Panasonic VL2020 model, althought the old didn't see bad and hasn't any mark around it. The voltage it has is correct (old battery has 2.84, the new 3.10).
I've thought too in the PSU. I tried to disconect the cd and the floppy, but nothing.
 
Have just now tried another A500 PSU and the 3.0 kickstarts roms and nothing.
How do I test the voltages?

Which is the voltage regulator? Is the 3 legs (or pin) square black box in the Blizzard? I suposse so.
With the "legs" or pins looking upwards, this is what I get:
Between the first and the second 1,69
Between the second and the third 3,29
Between the first and the third 4,98
 
I don't have an idea of electricity, but did I measure it right and is that ok?

If I get 4,98v between the 1st and the 3rd, doesn't it mean it has the correct voltage given by the PSU?

I tried the Amiga without HDD and Blizzard without Ram, and nothing.
I think if it works with the Hawk, it must not be the Amiga, and I don't know another to try.
I believe I will send it to Amiga Center in France. I'm already in contact with them. If they fix it I will post a reply so that everybody knows.

Just a question: at Amiga Center they've tell me it could be (I know it's very difficult to say without having it) around 150€.
Can you tell me another place to try (to find a cheaper one)?

Thanks for the offer Stachu, but I have an oscillator to overclock it, and didn't like the idea of putting fans, as I would like to keep the Amiga closed and without many holes, tubes and ventilation.
Suposse that with a 080 it has to get very hot.
By the way, the Motorola plaque gets very hot :madashell: if I let it for some minutes.
Could it be that the problem? I tell because I'm consider to try to repair it by myself...
Think I will measure the temperature digitally (I have an aquarium) and will let you know...

Hello:
Sorry to tell, but I measured again and the current is exactly 3,30v (sometimes shows 3,29, but Ï think it depends on the pressure I make with the voltmeter). The voltage in the other is 4,99v.
I measured the temperature of the Motorola mask and it read 34,1ºC (93,38º fahrenheit) in 4 minutes. Does anybody know if that's normal?

Thanks, I've already tried that a couple of hundreds of times...
 
Please don't tell me more... I've sent it to Amiga Center in France today.
I will let you know how they work...
Thanks!
