A1200 goes red when it reads a disk!

stainy · 08 November 2006, 11:22

Hi all.. I got a A1200 that had a green hue to all the outputs ( see other topic

)
I got a spare A1200 ( with no roms, floppy or keyboard )

So what I did was move my roms, floppy and keyboard to this new mobo.
All boots up fine

but when I insert a disk and it access`s it.. the screen goes red. and I have to reboot..

Any ideas???? al I know is that my A1200 with green hue is an original and the spare mobo is from a A1200 labelled `Amiga A1200 HD ` I`m guessing Amiga Technologies version..

are the floppies compatible??

RED: Error was found in ROMS.

Sounds like your ROMS are not in correctly OR they are broken.

But as you've already booted, this may be a (pardon the pun) a red herring.

yeah been there! it boots fine

Have you checked your video connectors for bent pins, also that your video cable is not damaged or crushed, barring that it may not be the amigas fault at all - do you have any other monitors to test it with.

Only other thought is trying to gently press on the video related and ram related chips while the machine is going and in fault state, also when the screen goes red - does everything stop ?

Or do your caps light etc keep working and floppy drive keep clicking.

Yes caps works and floppy keeps ticking..

ROM error, reseat or replace Kickstart ROMS (this can also be caused by worn insulation covering the back end of the pins that connect an IDE cable to a hard drive, aka short).

there are some power issues i think, drive motor causes some prw looses.
i saw somewhere on teh net somebody was repaired it with adding one capacitor. but dunno where i was saw it (aminet, some hacking pages), sorry

Hey Guys,

I might be wrong about this but if there was a problem with the roms causing the system to go red wouldnt it be the case that the keyboard caps light would not work and that the drive would stop clicking.

stainy · 08 November 2006, 21:34

Exactly! it boots so it`s not a ROM problem

Dizzy · 08 November 2006, 21:38

did you try to check the quote I made

this can also be caused by worn insulation covering the back end of the pins that connect an IDE cable to a hard drive, aka short

as a grope in the air,

have you thought of PSU / Power issue ?

it could be the spinning up of the floppy drawing to much from a tired psu ?

just a though.... I like dizzy's idea too

Hmmm well I was trying Kick Off 2 CV
Both disks red screen on me! tried an Amiga format disk.. that was ok... but both ko2cv disks run ok on my A500..

alexh · 09 November 2006, 13:59

Sounds like you have a panasonic floppy drive + AT Amiga A1200

One of the ones that doesnt do some copy protections.

stainy · 09 November 2006, 16:55

Thats exactly what I`ve got

Brass · 14 November 2006, 02:29

Sounds like a good piece of info to put into a faq.

JonSick · 16 November 2006, 12:22

I think its still worth checking the psuconnector is putting out the 5v and 12v shelf.
