Amiga1200 and BLIZZARD 123050mhz broker!? Help

[F0LLETT]

I hope you can give me some advice...
 I have an A1200 with a BLIZZARD 123050MHZ and a PC power supply modified for Commodore.
 I was doing some tests by restarting the A1200 several times and at a certain point, while it was restarting I was busy with something else, I smelled a very faint burning smell without smoke and a black screen....
 I quickly turned it off.
When restarted, the A1200 shows a yellow screen and the power LED flashes 9 times, then a black screen, and restarts.
The BLIZZARD remains cold, even the coprocessor remains cold. I tried changing the position of the BLIZZARD jumper but nothing.
 I removed the RAM, the coprocessor, the CPU, nothing...
the CPU/PROCESSOR and various integrated circuits remain cool
what could it be?

So does the amiga boot without Blizzard?
If so, then yes, it will be toast.

Highly doubt it will be because of a cap. A1200 can run with no SMD (except 47mf power ones) caps.
If it were a cap, it would have popped. You know when one of them goes pop, white smoke, bad smell and top will be missing or loose.

I would say, remove board from everything and have a really good look around the board. As yellow screen is CPU exception.
Check entire board (forget about Blizzard for now), there has to be something burnt up, if you smelt it. As BB already said, you may have missed smoke.

Could also be PSU, you got another to test, with just the A1200 mainboard (no Blizzard).

I have 2 A1200s and on both, the BLIZZARD IV 123050MHZ doesn't work. I also changed the power supply. I tried the BLIZZARD only with the CPU only, only RAM, only COOPROCESSOR but always a black screen and no IC or CIP gets hot or warm....they all stay cold.

Hang on, this is getting confusing.

Forget the Blizzard card first, pointless doing any tests until you know you have a working A1200 motherboard.
You said earlier, that the A1200 does not boot even without blizzard. You just get a yellow screen.
Now you say you have 2x A1200's and blizzard does not work on either?

Your going about this all the wrong way, so to clarify.

You have 2x A1200 computers fully working?

I've written a thousand times that it doesn't work and what the problem is with the Sk A1200.

 I repeat:
I was doing some tests by restarting the A1200 several times, and at a certain point, while it was restarting (I was busy with something else), I noticed a faint burning smell with no smoke and a black screen....
I quickly turned it off.
Once restarted, the A1200 displays a yellow screen and the power LED flashes 9 times, then a black screen and restarts.

I thnk there is a language / understanding barrier.

Yes we know, your Blizzard doesnt work. However your A1200 is also Faulty.
So logically, you would not use that A1200 to test.

So all your tests should be done on a working A1200 (in regards to blizzard card), as its completely pointless testing it on an A1200 if its not booting.

I have already said what to do. Regardless if you think there is no burnt area. There has to be some signs of smell on component or marks on blizzard/A1200 motherboard.
