    Philips 60pl9200d/37 Sunburn / spots??

    Hello. New to the site. I need help with my picture on my DLP. Red light for lamp came on recently and I ordered it and changed it. This did not fix all my problems. The picture was getting "ghost spots" or I will call it "sunburn or hot spots" mostly on bright images, sort of like a halo around bright images. The worst "sunburn spots" seem to be on people's faces when watching a program, the foreheads and cheeks have very bright areas. This same kind of thing will also happen when the "TV Show" I'm watching goes to a scene at night, but the opposite will happen and I will get dark purplish/ greenish shadows or blurring spots in the darker areas of the screen or on the actors. These spots and shadows move with the objects and are not stationary.

    I can also see lines moving up the screen, they seem to effect the blurry or bright spots a little, making them change color as the lines move.

    In the picture of Obama, you can see the "sunburn" on his face.

    In the second picture you can see the "sunburn" on the face, but also look above his head in the red area, you will see a discoloring "orange dis figure"

    I could not get a picture of the dark spots to show up on camera.

    Do I need a new motherboard? need help!

    I suspect DMD/Formatter board on optical engine

      Thanks, is that something fairly easy to replace? I am not a TV technician, but I'm pretty handy. Where is this part in the TV?

        Generally that board is in the middle of the TV.
        Make sure to swap the DLP chip off the old one to the new. (That'll be under a big heatsink - it's much like replacing the CPU on a motherboard)

          I would suggest following the removal procedure from the technical service manual of your model set,there maybe some adjustments to the replacement board

            It could simply be a dirty lens/mirror?

              Would this be the correct formatter board:

                Did you check the video I linked to?

                You couldn't guarantee a Toshiba formatter would work with a Philips.

                  Yes I did look at your video, you make it look easy! I also got my service manual to see if there were any other items I might need to do.(which did not show anything on how to clean the glass or convex mirror) On a scale from 1 to 10, how hard would this be for someone that has never done it?

                    Not my video . I don't work on DLPs.

                    The guy seemed to be able to do it fairly easily.

                      Well if it does become the DMD board, you would need to look at the existing board and match it via part number.

                        Ron, you seem to be correct about the DMD board. My question is what skill level is needed to replace this board. I'm getting quotes of 250 dollars to replace the board only. This does not include the part cost. I'v already replaced the lamp and I'm getting to the point that the cost is more then what the TV might be worth. But...that being said it is a lot cheaper then tiring to replace with something the same size.

                        Are their step by step instructions somewhere? I did down load the service manual for my tv but it does not seem to have instructions to do this.

                        Your help is greatly appreciated!

                          Changing of this board will require removing of light engine and to insure proper alignment you would need set of test Pattern files to align the light engine back properly.It's very labor intense,which should be performed by Tech which has had DLP experience repairing these type sets I'll attach my copy of training guide.

                            here's also the the service manual you must unzip using winzip or winrar
