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.

Check all your input cables & be sure they are snug on both ends, also check all your wiring connections inside the TV. you may have not gotten something back correctly or properly.

(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.

as far as I know that set does not have a lamp timer to reset.

THe only alternative is buying a transformer by 60HZ vs 120hz,

OR you can go some repair motor shop and reconvert the transformer by the frequency that you need.

Disconnect from the power for 1 hour. Go to settings - Picture - scroll down to Reset to Factory Defaults.

If that doesn't fix it, look for bad capacitors, or give it to a technician.

Make sure that all remotes are using same technology. Most remotes use infrared but many modern remotes are bluetooth and they cannot be programmed in infrared remote.

Check the capacitors well. You could also check other components. This could be caused by a partially faulty component that is failing after some time. Read more on this at https://www.electronicsqa.com
