This indicates a bad lamp. Get a replacement (make sure to check your TV for the code and type - this is listed on the right side of the TV and on the lamp case). Contact the store or a Samsung Service Center and give them the lamp code. Turn off the TV at least 30 minutes before replacing the lamp to allow it to cool. Remember to handle the new bulb with care; fingerprints can shorten the lamp life. The cool down happens when the TV is plugged into a wall outlet; if it is plugged into a cable box it may not cool properly. You need a Philips screwdriver (the screw is under a rubber cap that just pops off) and gloves. Unscrew this screw then remove the lamp cover; it takes a bit of force. Unscrew two more screws (one on the right and the left). They will remain on the body of the lamp. Separate the lamp from the engine by holding the handle and pulling it out. Reverse the steps to install the new lamp. Align the lamp cover with the grooves and secure the screws. If the lamp cover isn't properly closed, the TV will not turn on. There is a protection circuit involved.
I hope this helps.

Samsung dlp dnie
just from personal exp the easiest thing to do may fix or at least make it better. if u see puffed and leaky caps on power supply replace capacitors. if really dusty clean. both previously mentioned and both helped me. my tv was completely dead and replacing caps got it to power back up and work. it takes two trys to come on but works great so far. then i cleaned every nook and cranny with a small vacuum hose and different size/angle brushes that could be attached to hose. i only took out the psb board with caps and didnt touch anything in there that i could mess up. just cleaning helped enhance the colors. right now this is the best picture ive had on a tv and it was completly dead when i got it.
SAMSUNG TV HL-85687W picture is dim
(Please check your model number - it appears to be incorrect, I believe it's HL-S5687W) 1) How old is the lamp? (how many hours on it)2) Is the lamp an original equipment lamp, or aftermarket?It's either the Lamp itself (it's not common for a sudden reduction in brightness), -or- the Lamp Ballast has gone bad. This is the power source for the Lamp, and although they usually die completely when they do go, sometimes they will act just as you have described... they fail into a "low power" mode.If the lamp IS an original mfr lamp, and if it's nowhere close to being near "end of life", then I'd say it's likely the Ballast.Prices for the original Samsung lamp run around $100 onamazon and others.The Ballast p/n BP47-00037A has a cost of around $50 to $100 online. Google those p/n in "Shopping"The Ballast can be replaced without great knowledge, but will require some dis-assembly, and CARE.WARNING - Dangerous, and even lethal voltages are present inside your TV set. Do not attempt this unless you are trained in these kinds of repairs. Leave the TV unplugged for several hours (or preferably a full day) before attempting such repairs.
