SCSI control on analogue? Testing voltages are fine. is this called scsi voodoo :?

Yes

Hi cheesestraws, yes with no HD attached, it boots from floppy, occasionally it hangs and tells me there is a addresse issue I have tested the HD on a scsi card on my G3 and it’s fine, no errors, so it’s definitely a problem with the classic? thanks for the reply

Could this be a ram problem?

Hi, real pain this one, analogue and logic are both recapped, when I attach a hard drive and switch on I get the following error . boots without drive attached from floppy disk and on board system. its a revision 1 classic. thanks

If there is power to the screen, a small orange glow can be seen to the rear of the crt. power on and check if there is indeed that glow.

It’s was a cold solder joint, when the image returned, it was dull, however I think a previous owner had tampered with the pots, brightness turned up .. job done check the adjustment pots solder joints, I tend not to reflow, I prefer to do a new solder after removing the old, reflowing does not always work good luck

Did you adjust the brightness?

Hi all, just recapped the analogue board on this classic and now I have a screen that is slightly warped top right. It’s not highly noticeable , has anyone got any idea?

Hi, the Mac is switched on, rear casing removed , I can hear power going to the crt, but no life soft power no longer works. even with motherboard removed, there is no change

Hi all, again, so as the title says it’s a colour classic.. I’ll try to keep this brief.. as usual I recapped both boards, with emphasis on the analogue, and hey presto, soft start, and eventually power was restored, the machine functioned once again. I was very happy , then last week I switched it on for photos, and the hard drive was not recognised, so all the checking began, after the Mac was back together, nothing, nada, dead !! No fan activity, no clunk when power was switched on, just a very feint hum, power is going in, s

Ok so problem solved, PP1 Phier replaced, wht da ya know

Hi all, this has been totally recapped, analogue and logic, but I’m getting what only can be described as interference on screen, both sides. I expect you’ll tell me it’s a cold joint somewhere, I just cannot narrow it down, any help would be much appreciated, thanks

Although I am no expert, I have 3 colour classics, all undergoing resto... stick with the logic board for now, if you can power the machine from the keyboard (soft power) the analogue board is functioning for now. the empty slots do not need to be filled to enable your board to work, you do not need a battery to power up either, so the fault Lies somewhere else. removing the egret chip, and replacing after a clean is no easy task! you need some serious skill to remove the chip without pulling pads, and resoldering requires a degree of skill, unless your

I feel your pain, these damn machines are so temperamental, I’ve just recapped analogue board and it was working fine, then this morning , hard disk not recognised, and later no power! I hope someone can help you, I have a feeling the pot is not at fault.
