Broken A500 CIA

Hi!
Sorry if this has already been asked, I tried the search function but didn't find anything usefull.

Three years ago, my A500 died while transfering a disk image to a C=1541 drive.
At first I thought the tranfer program just froze, as the machine didn't respond to either mouse or keyboard input (the picture on the screen were perfect, non corrupted).
But when I reset, all that I get was a grey screen, no drive click or anything.
When I open the machine it was very obvious that the CIA that drives the parallel port has died (it runs very hot).
The cause of the problem was a faulty 7406 on the C=1541, wich acts as a protection for the VIA6522, unfortunatelly there is not such a protection on the A500.

I had no problem fixing the drive,as the faulty chip is standart, but I had to put the A500 on storage as here in Argentina is almost imposible to get spares.

Now I have the posibility to get a replacement CIA, so I'm asking you:

Do you think that a new CIA will fix the problem? Or something else is broken?

Thanks in advance. (And excuse my bad english)

I already did that, but the only difference was that the drive 'click' once.

I read your post earlier this afternoon, Motorollin, and I get very depressed.
Well, just arrived from work and open the A500 to test again the CIA swaping, it did somewhat the same that I described earlier, but it was no drive click, just the motor spin.
Then I remove the bad CIA (which was now in the EVEN CIA place), I turn the machine on, and after some flashing screens (can't tell the colors as I'm using the monochrome out); nothing. Then I insert a disk on the drive, and, although the drive didn't spin nor click, the bootscreen prompting for a workbench disk appeared.
Please, tell me this is good news!  :cry:
