Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television

1 Answer

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?

Left half of screen projects normally. About a 6" gray band is in center vertically, and right half of screen is nearly black although picture is still visible. Problem began with 6" gray band restricted to right margin of screen, then darker band began as an equal width, and progressed toward mid screen.

No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.

I have a 56" DLP Samsung (HLR5668W) Right side goes solid black

The color wheels will never fix an issue like that. The only things that will cause that issue is a bad DMD board which is part of the light engine or the digital board which is not. Freak Squad need to replace the digital board.

you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

Possibly a bad light tunnel assembly if the part is only a shadow effect. If not then probably a bad DMD board. The DMD board is part of the light engine but needs to be replaced by a technician.

Half of screen blacks out

sounds like power supply caps or caps in the dm board

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.
