I recently acquired a consoliized MVS and it's working all well and good apart from the fact that the screen is tinted green on my crt.
Any help with this problem appreciated
MVS problem: screen tinted green
Re: MVS problem: screen tinted green
Some questions:
What's the tint like just slightly altering colors, or screen completely green? Also does the image appear particularly darker/lighter? Connecting via scart plug? Same effect on all screens or just on a particular tv? Does the picture look perfectly normal if you turn down the green on your tv or is the picture some ow still 'off' [dark/bright/other colors/whites not correct]?
Some immediate possible suggestions:
I've had an image appear bright/blown out and slightly green due to a slightly over strong sync before on one trinitron, the same device appeared fine on another [older] trinitron. A variable resistor to tweak the sync down a bit cleared away the green and slightly overbright picture. [Incidentally normal consoles appeared fine on both tvs].
Similar problems may occur if a line in the scart plug is causing grounding errors etc. However, I would expect that the image is slightly green on all tvs if that was the case.
If the image is completely and utterly green via scart you may well be outputting component from the device - a common addition to more 'international friendly' consolisations. Some tvs can accept component from scart some try to interpret it as rgb and simply get a green image.
If the image is completely green AND dark, the red and blue signals may not be coming through [most likely a broken connection, probably somewhere on the cable]
Hope this helps!

Re: MVS problem: screen tinted green
The other colours are still there (it's not a composite output problem), but the green tint alters them, some not much, some a lot - it virtually nullifies orange and changes it to yellow, which makes playing Puzzle Bobble even more exciting 
.
I've only got a cheapo CRT with not a lot of options to play with, I can get rid of the green tint by the turning the colour right down on my telly but the colours remain compromised.
in the next few days and see if that's the case (I hope so).
Thanks for the response

I suspect that this could be it and that something might have come a bit looose in transit. I'll open it it upSimilar problems may occur if a line in the scart plug is causing grounding errors etc. However, I would expect that the image is slightly green on all tvs if that was the case.
