SOURCE: My t.v. shuts off after a few minutes

try this link...it tells you what the LEDs indicate. Apparently the cover on the back is not sealed properly, my guess is that it is a fan not working properly or some other reason the set is overheating.

SOURCE: T V won,t come on and timer lamp on front panel

Your lamp hours have expired. Try taking the lamp out then putting it back in. The TV will go to a reset menu for the "new" lamp it thinks that you have put in. From there you can reset the lamp hours from the menu. It it doesn't work, the lamp may be burnt, and you have to replace it.

SOURCE: Why won't my Samsung HL-R4667W DLP tv turn on?

Theres a cover on the back that is vented w/4 screws on like the corners,also theres a symbol that looks like a "T" on it,take that cover off and right behind the symbol "T" an arm like plastic piece is what hits a lever inside when then cover is installed ,flip that little blue lever up and down a couple of times with the set unplugged reinstall cover making sure the "T" is in the position to hit the lever and tighten not too tight.
if this don't work it may be your colorwheel.Good Luck!

SOURCE: Samsung HLN507W turns on for

Samsung HLN507W turns on for about one minute then shuts off, three blinking lights stay on in front. It is not the lamp, nor the blue lamp cover switch for sure. I unplug it and immediately turn it on. It always does the same thing: comes on for 1 minute, then powers down - there is no wait time in between unplugging and powering on. All fans seem to work and I cleaned the dust out of it. Help.

No picture, have audio tv shuts off after 2 minutes


If you've replaced the lamp with a Mitsubishi lamp and not a generic, then the problem will be in one of two areas. Its either a bad ballast board (lamp power supply) or the color wheel assembly. If you've gotten a generic lamp, you may find that that's the reason its still not working properly. Many generic lamps are unsuitable for this product and will cause issues like low brightness, intermittent no start, and short lamp life. Also, make sure that the lamp door is properly installed because there is an interlock switch which will open if the door is not aligned properly.
