This kind of problem occurs due to failing DLP chip (also known as DMD chip) mounted on board on light engine, this chip makes an image that projected to TV front screen and lamp is light source in this process.

Replacement of DLP chip in TV will help to resolve the problem, please click following link to view DLP chip image and price info if you wish to replace it in TV but please note that it would not be an easy work, lots of things will need to be removed/ take apart in TV for that..

If you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote that could be $400 or so...
