Blizzard 603e + BVision Power Problems?

[badgerme]

Delshey: Have tried the on/off approach as well as moving the card in/out at a fraction at a time and still the same situation - dim green light - no boot
When it did use to work - I would normally have to soft reboot (CTRL + 2A keys) in order to reset it and get the dim green light to go bright green - is this normal or does it sound like the card was either on its way out - or simply reinforces the original PSU issue by way of the 5v rail not being 'strong' enough at 4.7v.

I think I'll skip the upgrade..... I wont how much a repair will be. If I have shorted the ram on the 68k processor - does that basically mean - game over?

I cant see that I have as the card worked with the RAM in for some time....

I do hope Mr JJ can help me out

Have tried holding ESC for the menu whilst turning on and nothing..... I've tried soft resetting it and holding ESC and nothing......

Does this card boot without any RAM in? I just wondered because I could take the ram out to eliminate it as being a suspect in this debugging process.....

I've sent stuff for repair with him recently. He's pretty fast at diagsnose/repair/email... you should get an email message from him any moment. As for the cost, depending on what your card has, it can be pretty expensive.. ~EUR120... his service is expensive, but VERY GOOD.
 
Unfortunately you might have caused a problem in the card while handling it (blame static charge)... it uses to happen if you don't have/use an antistatic wrist strap.
 
And before you ask, yes.. I killed my BPPC like that, then I had JJ to fix it, got it back (and working perfectly) and I immediately bought a wrist strap.. (lesson learned....the hard way).
 
Good luck.

Try what delshay said, specifically pulling the card out a little bit. Sometimes the connector can get loose. Also clean the motherboard card edge with cleaner to be sure there is good connection.

If you shorted something or the 68XXX is dead the card will not boot. I tried a blizzard and without ram I can get the boot menu.

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.
