Amiga1200 and BLIZZARD 123050mhz broker!? Help

[marco920]

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?

Yes! It doesn't start without BLIZZARD.... but I've described how the A1200 behaves without BLIZZARD 3. I wanted some information to understand what it could depend on and what the problem could be.

I own a BLIZZARD 123050MHZ IV non-SCSI. There are no signs of burning and no integrated circuits get hot. The Blizzard costs €400, buying it again is not an acceptable solution; I would like to repair both.

I've already used another power supply without BLIZZARD, but the A1200 always gives a yellow screen and 9 power blinks.
Could it be the SMDs?

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 YELLOW screen and no IC or CIP gets hot or warm....they all stay cold.

I own 2 A1200s..
 BLIZZARD does not work on either of the 2 A1200s.
ONLY 1 A1200 froze with a yellow screen, 9 blinking LEDs and then a black screen and restart.

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.
