Hey Everyone,
Since my father passed away, it seems like every electronic device in the house has been having trouble.
OK, I've spent a lot of time, and mainly money on my A1200T. A few months ago, I started having some trouble with the output of my DCTV. Pics load/save, and display fine, but in DCTV Paint, the area with the palette is all mottled grey. (Kinda like a ghosted button) I tested this DCTV on another miggy, grrr, it's fine......
Then today, playing .MODs, one of my old favorites Aevias (by DeathJester) some of the voices sound 'weird'... One sound is way too high a pitch....
So far, these are the only issues... I've tried numerous other graphic/sound programs, so far everything is OK... but anyone have ideas? Bad caps? CIA's? Global warming?
Anyway, I've gotten used to dealing with the 'worst case scenario'. If my A1200T is not long for this earth, how hard/expensive is it to get an NTSC A1200 motherboard?
Sooo, I haven't made any HW changes on my sys. for at least 2 years (hard to believe :) ) Nothing that I can think of as for software either....
I have a sick feeling... sigh...
here's some specs of my miggy:
A1200 Power Tower, P5 1260, DCE 12xx SCSI, 256 MB fast, OS 3.9 w/BB1 + 2, Drives: 8.5GB IDE (SYS: ,etc.) 3GB SCSI, 100MB Zip, A1010 ext. floppy..beyond that, just the usual printer, scanner, modem....
Software: Lots of Hacks :lol: MCP, Magic Menu, ReqAttack, PowerSnap, FBlit, ToolsDaemon, Virus Checker 2.5 ... Although, I have been running all of these for many years on this sys., and all except FBlit on another A1200 for even longer....
Please, someone give me some (even sorta) good news.....
'Help me, Obi-Wan Kenobi, you're my only hope....'

It could be bad caps.. The early 1990's was not a good time for caps and the A1200 and A600, even the Sega Game Gear are known to have issues related to the caps going bad. A typical A1200/A600 sign could be a delay when rebooting.

I'm gonna go with the caps too...

Could also be a power supply issue. But mottled sound definately suggests caps. You could change the psu first if you have a spare to try(easy stuff first).

@Everyone: First, Thanks much! Second, EEeeeeewwww! I kinda figured it was the caps.....
Damn :madashell:
Well, anyone know where to get NTSC A1200 motherboards?

Just re-do the caps. If money is no object, Amigakit has NOS A1200's!

Cant be too much hassle to replace a few caps. I've never done it on an Amiga but i have successfully replaced the caps on a sega gamegear and that is small and i am honestly no good at soldering. If you are considering a new motherboard you have nothing to lose by attempting to replace the caps first. Just take your time and do it slowly and you should be fine.

But buy some proto boards and components first to practice on. I spilled solder and it went under one of the chips. My A1200 was never the reliable after that.
