Hantarex MTC 9000 - Missing colour red - advice or UK refurb/engineer?
Hi All,
I've got a UK-edition Playchoice 10 cab. It's generally been reliable, but the other day it suddenly (mid game) lost the colour red. There seem to be no other effects - the image is still sharp and steady, just no red (or perhaps very very little red, hard to tell).
I've done some basic troubleshooting by checking voltage on the red, green and blue lines, all the way through to the points on the neck board (marked on 4th image below). I see about 10-12v, depending on the image. This seems roughly the same as the green and blue signals.
The red gain and red cutoff on the neck board do nothing. I've not yet tried metering these components, because I don't really know what I'm looking for.. But I'll post an update if I find something there.
I've also not tried removing the neck board and re-seating it yet, because I've never done that before! (Does it just pull off on these monitors?)
Pics:
(red circles a points where I metered approx 10-12v)
Has anyone got any thoughts on what to try next? The only equipment I have is a multimeter! (and I only have a basic knowledge of electronics)
Any advice would be gratefully received.
Also - Is there anyone in the UK who offers a full refurb service for this monitor? It could probably benefit from a cap replacement and a refresh of the tube. (I really don't have the time to do this myself!)
Thanks everyone
