My samsung DLP hls5687wx xaa shuts off by itself. How do I fix it?


The lamp ballast or Color wheel might be the problem. We have experienced both issues with the tv shutting down. Also check the hours on your lamp as it might be getting old.

My remote only works within 2 feet of the sensor on the tv. This is true for 2 universal remotes and the original remote that came with the tv. I have a Samsung 42" DLP HLR4266WX


Chances are that the sensor has gone bad. If you know how to get to the circuit board that it is on, then changing the board would be easier than just changing the sensor.

Closed caption


You have to activate the closed caption option on your charter cable box. Power off your cable box and immediately push the menu button. A menu should appear where you can toggle captioning on/off. Good luck!

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!

Problem may be lamp is failing or ballast which operates lamp may be Bad. Could also be Temperature fault from Inoperable fan or Color wheel. Bulb of course is first choice of possible problem followed by color wheel then ballast. Color wheels usually will start making bearing noise when they start to fail. Hope this helps.
