Hi i have 3 Amiga 2000. The 2 of them i can connect to my tv with a scart lead and they work perfect. but the last one shows only black and white screen. Are there something i can do to change it in workbench? it works fine with an old amiga monitor, i have tried 3 tv but the amiga is black and white on all of them.

Do you have also 3 SCART cabels?

Do you see ghost picture? I would say that SCART cable that you tired is wronly wired.

Hi its the same scart cable i use, i only have one that is special made for the amiga. I just use that one between all the amigas i have :-)

The A2000 can develop a fault which leads to colour not being shown in some circumstances. Are you able to test on a monitor? (VGA adaptor + ECS chipset or Amiga monitor)

My A2000 shows monochrome on TVs using any A520 RF modulator (used to work in colour long ago), but still works in colour on a monitor.

Hi on my old amiga monitor the colour is just fine, but with all the televisions it is black and white

As far as I know all A2000's output greyscale via the composite out. This has been the case with the two units I've owned. It's a known thing. As far as I recall, an A520 is needed to get composite out of an A2000 -- well, short of using non-Commodore solutions.

Is it so that 2 that work are old crt tvs and non working is lcd-tv?

Are you sure that cable is wired correctly? Like this : http://www.ianstedman.co.uk/Amiga/am...iga_scart.html

Open it and check

Thanks i have a look at it :-)

Hi its the same television i have tried, all crt

PAL v NTSC models? Amiga monitors don't care and will display both, but your TV might only support one mode.

On RGB it doesn't matter whether NTSC or PAL, there's no color encoding at all.

The only way to get monochrome is with composite (which doesn't come out of the DB-23 port) or a (very strange) short between R, G, and B...

Is the picture slightly blurred (=composite) or really crisp?

[lassie]

hi i would say the picture is very crisp

[Zac67]

Hmm...

Pin 22 carrying +12V?

Pins 3, 4, and 5 separated by ~150 Ohms?

Possibly some kind of modification from a previous owner?

[Digiman]

Amiga SCART RGB and 1084 monitor lead use the same pins and same signals for image generation so the only thing that makes sense is a grounding issue as your monitor uses 9 pin D connector? (SCART has more than 1 ground pin but 9 pin monitor cable has just 1 IIRC).

the composite is black and white out on 500's and 2000's I don't know why they changed it the 1000's had color. I will look for an old article telling how to modify it.
