Question about Samsung DLP HL-P5663W 56" TV

1 Answer

Samsung S5687 w/hl shuts off after 20 seconds

The TV has worked fine for the 13 months since I bought it. Xmas morning I turn the set on and 20 seconds later it, the screen goes black, then a few seconds after that, the set shuts down. I then get the three lights on the front blinking. I tried unplugging for awhile and messed with the little blue switch by the bulb door. The one fan I can see still runs. The same scenario plays out every tme i turn the TV on. The TV gets alot of use (8-9 hrs /day) but would have thought the bulb would last longer. Do you think its the bulb or should I call a Tech?

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

SOURCE: Samsung HL-P5663W, picture goes black after some time

I fixed it. Went back in after a twenty min. break, figured if it's broke I can't break it again, might as well try to fix it(out of warranty, so much time on 1st. bulb, after fixing I found out had 8463 hrs. on 1st. lamp! WOWW most i've seen on any strings out there,and I'm really cheap and inquisitive) But this is how I did it. pulled off covers. looked around pulled light box out checked connectors and resistors visually for burns, none found, then I see a clear plastic sleeve covered group of wires it was plugged up at the ballast where i was working earlier but not the other end, so i looked around for the plug to insert it, couldn't see any where. I felt on top of a silver polished panel w/holes allover, there on top, at the right side of the silver panel was a plug for it. I plugged it in by removing fan and cooling fin assembly, for room to work(and good chance to clean dust from the fins and fans. I tilted silver panel down to see the top, after some removing spring loaded screws holding cooling fins, (the screws ave very light spring tension and won't pop out, I swear, keep track of springs for reassembly later) plugged it in(only goes one way, don't force it, flip over if it doesn't fit nicely) replace all removed parts in reverse order and reinstall covers, plug up, and mine powered on almost instantly. After that and spending 2 hrs. online trying to go through all the strings everywhere about these problems. It came down to trial by fire. I hope this helps, reply if it doesn't.

TV goes off after 20 seconds Samsung HLS5086wx


First Take off the Lamp Door and replace it back the way it was secured with all of the screws. Doing this will reset the safety interlock switch which heats up and opens the circuit causing the set to shut down. After doing this and the set still shuts down check the lamp. Depending on the amount of hours on the lamp it may be a bad lamp. They will fail with out any obvious signs. If the set shut down and goes straight to the Stand By condition then you have a bad Power Supply. If you hear a whining or buzzing sound then you have a bad Color Wheel.

Samsung DLP turns on and off - cycle repeats


make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast.
Call a local tv repair shop to further diagnose the problem.

HL-S5687 DLp tv


your keeping a part that is warming up and shuts down your shutdown that protects the tv from burning up... cooler... to find this you might need a hair dryer or a can of freeze mist.
I believe the left side is your high-voltage section.
you can also let it warm-up without the fan .. let it shut down and feel parts with set unplugged to see what is running hot.

Samsung DLP TV HL-R5667W shuts off intermittently


Afraid there is no simple answer to this. This set has multiple things that could shut it down, one may be the balest needs a upgrade , this could be why it seems to be eating lamps. Another is what sounds like a fan is a color wheel , these have known problems of failing, and when this happens sometimes they shut down the set. And finaly does the set have good ventalation, overheating can cause huge problems with this set

Samsung DLP HLR5668W has mostly dark picture + grinding noise


Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
