Dead Blizzard 1260?

[Retrofan]

Just a question: at Amiga Center they've tell me it could be (I know it's very difficult to say without having it) around 150€.
Can you tell me another place to try (to find a cheaper one)?

Well, as you said very difficult to quote repair cost without having card in hand.
What I can offer you is that I buy your card as "broken" and sell mine Blizzard 1260  060@80MHz (upgraded by me from Blizzard 1240) which is 100% ok.
By doing so you will avoid headache and risk that card can be "dead for good".

I'm afraid none will tell you cost of repair without seeing the card first.
If you think it's worth it please start new thread; maybe someone will be interested with repair.

Stachu's work is proven and of high quality, that's an offer that needs considering.

the fault is somewhere else..3.2v is low it should be reading at the very min 3.307-9 or in the 3.3v range.

The voltage should be 3.3 volts, not 3.3something. 3.29 is within .01 volts, which is perfectly acceptable.

Thanks for the offer Stachu, but I have an oscillator to overclock it, and didn't like the idea of putting fans, as I would like to keep the Amiga closed and without many holes, tubes and ventilation.
Suposse that with a 080 it has to get very hot.
By the way, the Motorola plaque gets very hot :madashell: if I let it for some minutes.
Could it be that the problem? I tell because I'm consider to try to repair it by myself...
Think I will measure the temperature digitally (I have an aquarium) and will let you know...

I understand you; silent is worth a lot of money :-)
No problem to downgrade to 50MHz; just oscillator needs to be replaced.
And as the CPU is 71E41J mask the heat generated @50MHz is very low, so you can close trapdoor with no risk of overheating.

The heat generated by 060 depends on mask version.
Early mask versions were quite hot and will not work above 55MHz, but they can operate @50MHz without additional cooling (some users said that trapdoor must be open to avoid random crashes during hot summer days).
Last 71E41J versions are proven to be cooler at the same clock speed comparing to first revision.
060 with latest mask can be overclocked up to 110MHz (I have 2 CPU's proven to work @106MHz by myself).

take away the last to digits iv posted and it reads 3.3v.   input voltage is fine 4.98.

yes it should still boot with 3.29v but it`s *not* correct. get another user here with the same card to check the voltage or for a matter of fact anyone who have the time check the regulator output lets see how many return here with 3.2v.

here on my system on a overclocked system if it reads 4.92 it`s starts to lock-up/crash.

when the voltage is 4.94 and above it works perfect,this is why my system is very stable 5.04v...voltage is taken as far away from the PSU point which happens to be the Bvision..( voltage reading taken here ).

3.29 and 3.3v may not make a difference on some card but *may* effect others.

Hello:
Sorry to tell, but I measured again and the current is exactly 3,30v (sometimes shows 3,29, but Ï think it depends on the pressure I make with the voltmeter). The voltage in the other is 4,99v.
I measured the temperature of the Motorola mask and it read 34,1ºC (93,38º fahrenheit) in 4 minutes. Does anybody know if that's normal?

try pulling the card out a little when it is connected to the A1200 motherboard connector do this with the computer off,then turn on.

Thanks, I've already tried that a couple of hundreds of times...
 
Please don't tell me more... I've sent it to Amiga Center in France today.
I will let you know how they work...
Thanks!
