Default Mitsu HL67A750A1F Red lamp not working when image is darker

The red color disappears, but only when the image on screen is fairly dark (a night scene). When really dark (picture of a small candle) even the green disappears, leaving only blue.
I already changed the red lamp but that did not help at all.
I'm thinking that the problem might be on the board level but I'm looking for guidance as to which board is the problem and if this behavior is even worth fixing.
Please help

Your dealing with a dead technology, DLP is no longer produced and very few people here are using them. Not many service centers repairing them either, good luck have you checked YouTube they have some repair inoposted on there.
