I have a Samsung HL-S5687WX/XAA and the screen is completely white and there is now sound on AV1. If we plug in our WII and go to Netflix on AV3 the picture and sound are fine. The HDMI source gives the message weak or no signal. What could be wrong and how do we correct this?

From past experience only two things can cause this. First is the cable going from the digital board to the DMD board. Make sure you disconnect the power, and use caution disconnecting the plug or tightening it, not to strip the plastic tension screws. Don't use power screwdriver for loosening or tightening this DVI type cable. Second is the digital board itself that can cause green interference lines in picture. For this, you may consider sending the module, which is the large shielded box where the cable screws on to back of set, out for service or rebuild. Reason being it is cheaper than buying replacement digital board. If it is the board itself, start by running a search on it by part number to see who has one. As I recall, the part number should be BP94-02084A, on your model. Good luck, Russmann.

Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

Their is no more you can do.
You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

SOURCE: Tv shuts itself off

Look for the computer processor inside the TV. It needs to be cleaned. A can of compressed air will work. The processor is overheating and causing the tv to shut off. Look for the small fan that is supposed to keep the processor cool then remove the dust.

Good luck!
