Blizzard 1230/50 MKIV problem (Black Screen)

[Stedy]

Hello,

A good thing to try, it to clean the A1200 CPU slot connector and that of the card. Isopropyl Alcohol (used in tape head cleaner fluid ) on a cotton bud, rub it across the A1200 motherboard connector for the card.

If you can get some contact cleaner, spray it into the connector of the Blizzard 1230.

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.
