A500 (1.3) output in black & white

[gurthuk]

Bought an A500 off eBay which arrived today. Everything works fine although the TV image is black & white almost all of the time. It briefly jumped into a very fuzzy colour screen before jumping back while I used my Action replay MkIII. I'm using the A520 modulator to connect to a TV so I'm thinking it could be that, I've flicked the H / L switch on the modulator to no effect.  Has anyone came across this problem before?

Spent this evening just cleaning it as it was a bit of a state - notes to self when buying any computer equipment off eBay:

1) Ask if they smoke
2) Ask if they smoke in the house
3) Ask if they have a dog
4) Ask if they ever wash

Perhaps I could try the A520 on my Amiga 1200 to rule that in or out - should work shouldn't it?

No such thing as a silly question...

I haven't checked the tuning to be honest. It's already tuned in for my A1200 so I simply swapped the computer and it fired up the screen instantly. The black & white is very crisp.

No I'm not sure, the keyboard is UK so I presuming the A520 is the original one and so PAL.

Yes, I got a very faint picture. In truth I should have tried tuning the TV in to that. The audio through the A520 works.

Yeah SCART is pretty much the way I'm going to go with this. I'd just like to rule the modulator 'in' and not discover the fault is with the A500 motherboard.

Did think of that but only after packing the lot away for the night. A job for the weekend I think...
