Blizzard 1230/50 MKIV problem (Black Screen)

@EnyGmaTiK:

There are two jumpers on the card. One for the ramspeed and one for MapROM. Make sure the MapROM feature is disabled as you havent got a SIMM installed. There should be instructions for the jumpers printed on the card.

No use i must have a dead bliz.

I've cleaned the board, also i've cleaned the contacts with alcohol, no dice...

I kept one jumper on the first 2 pins (No Map) as i don't have any SIMM connected.

Still got a black screen.

If i keep the miggy on for a couple of minutes, the bliz is warm. I don't know what this means exactly, maybe a dead CPU?

Hi,

A long shot here.

Does the card have a crystal oscillator next to the 68030 (a small square metal can)?

If the card has been overclocked in the past the oscillator could have been socketed and fell out.

Yes, it has a small square can.
