Picture is OK, but colors are off and there is a blue star background that shows on dark colors.


Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

Tv gone green/blue and sometimes red in top right corner


If you have a Sony rear projection LCD TV then you have a failing optics block. LCD TV's are not affected by external magnets like CRT TV's were. The optics block issue will only get worse and needs to be repaired by a technician.

Problem with a colour display on Hisense tv


If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

Thomson Scenium 52''Rear Projection TV set -


you have a laser that has gone out blue or green take the face off and see which of the colors you need you can still find lasers on ebay if you need one but it will require someone with a little expertise to replace them. if this is not for you then its time for a new TV this is probably the best option its more expensive to fix in most cases than to replace..........I hope this helps

Toshiba colours gone wrong


Yes it is repairable. One of two things is wrong. The color wheel is going bad or the DMD board is going bad. These are the most common repairs needed for a Toshiba. I hope this will help.
