As I mentioned it seems problem with DMD board where DLP chip is mounted which generates an image that projected on TV front screen. DMD board would be located at lower center of rear of TV, needs to remove lower back cover and find a cooling fan and DMD board is behind that fan. Please click following link to view DMD board image which will help to locate it in TV..

you think this need to be replaced?
Expert:  Shahid replied 10 months ago.

Yes, first I would replug the connectors on DMD board to refresh the connections to see if it helps and if problem persist then replacement of DMD board will help to resolve the problem.

Thanks.
