Blizzard 603e + BVision Power Problems?

[delshay]

Ok guys I've just tried the new power supply and the floppy connector on the motherboard now reads 4.97v! (a big improvement on 4.7v)

Only problem is that it still doesn't get past the dim green light and the black screen.

if I take the card out the Amiga boots and works fine.

I've different RAM chips and still the same. I really don't think it's the ram.

Is it knackered? Does anyone still know if Jean Jaques is still repairing Amiga hardware in France? (http://www.amigacenter.com) ??

Any tips/advice to get me back up and running will be really appreciated!

Cheers

put the blizzard ppc card back in on it's own,keep the voltage @4.97v.

turn the amiga on,do this about 5 to 10 times.  give it about 3-5 seconds when turning on the amiga. if it still refuse to boot try this.

pull the blizzard ppc card out a little away from the motherboard and repeat above.

post result back here.    

i hope you dont have those big simms that may have come into contact with the 68k processor.

have you tryed what i said in my last post.

without ramand hardive pull out you should see the amiga boot screen where it ask to insert a floppy disk.

but at this point you are just checking that it boots to this screen,if so the card should be ok.

when you inserted the new ram you may have disturbed the card contacts as dust builid up inside the case,this is why i ask you to pull the card out a little.

also when you insert anything with the blizzard still attach to the motherboard the dust which builds-up inside get in-between the contacts and what happens is some of the contacts can get stuck not springing back.

this is why when i insert anything onto the blizzard i hold the card so very little movement accures
and not put pressure on the contacts.  
 
ok remove the blizzard ppc card from the motherboard completly and then re-insert the card.

you may want to check the contacts for dust before re-inserting the card back.


***   also look at the blizzard ppc contacts,are all contacts in-line,what you are checking for is any of the contacts sitting further back than normal  *** IMPORTANT

OOPS i forgot i reconmend some contact cleaner & dust remover.

**OTHER NOTES EXPERTS ONLY**

when A1200 cards are brand new their are very hard to install due to the spring contacts being new. over time after many inserts the contacts do not press as hard onto the motherboard contacts.

to get my amiga super stable i got a small pin and push all 150 pins foward on the blizzard card not too much towards the centre of the card.

when i try to re-insert the card don't let the card wiggle left to right as if you are trying to break the connector,keep it in-line all the time this is best done with the ram module allready attached.

if you have a A1200 desktop hold the card from the other side ie remove the top of the A1200 so that the card does not drop down add trapdoor cover while still holding the card in-line with the motherboard.

NOTE: the card will be a lot harder to install than normal but this will bring it back almost to a level when card was new. it will grip the motherboard connector a lot harder the card will also be stiffer ie less movement.

now when i turn on my amiga it boots first time every single time without a single problem.

**only card with intermitten errors you can try this**.

VERY IMPORTANT:  if all has gone well **never** disturb he card ie change ram modules leave it alone. if you need to change something hold the card in-line with the motherboard so there is little movement.

do not bend the pins towards the centre to many times it will not break lets say after 3-6 times
but it will not grip the motherboard connector as well as the very first time.

THIS IS FOR EXPERTS ONLY its best done on the first time and leave it alone forever.

EXTREAM IMPORTANT: if you bend the pins too near the centre when you insert the card you can bend the pin to the other side of the card and damage the pin(s). there is no room for mistakes here best to get it right first time.
