Page 1 of Lost colour on Region 1 Disks on Matsui DVD-110

We did the multi-region hack on our Matsui DVD-110 and it worked fine for about six months. But suddenly all our Region 1 disks are playing in black and white only, while Region 2 disks are fine. What can we do to get colour back?

The same thing happened to me(with a different player).
It is to do with the colour settings- you must make sure to watch reigon 1 disks your dvd is set to NTSC.If you haven`t got the option to change this then I don`t know how, but when we purchased a new t.v we got our colour back.
Weird!
