TV remote on my model TXL2791F won't turn TV on. When I press the power button on the TV itself the little timer light blinks and the TV makes a ticking sound for a few seconds. If I press the power button again the blinking light and ticking sound happen again for a few seconds. If I repeat pushing the power button on the TV again the blinking and ticking will then go on all day long unless I unplug the TV for 15 minutes or more. All during this time the screen is dark. Just before this happened some one else was operating the remote in a haphazard way before turning off the TV. Is this a hardware problem or a software problem?

You are likely to have a module bad....part number BN94-00864A and if you take it out (unpluggs) you should inspect it for capacitors that may be domed or pooched up at the top. If so they should be replaced first before getting the module as the capacitors are about $1.00 each. Do a search for Samsung parts online if you need the module and call them toll free

I have the same problem with my 56" HD Samsung. It shuts off automatically and then on the power button the word Lamp is light up in green. Sometimes I can turn it back on but other times it won't and I have to wait a bit. It's been embarassing a couple times when people were over for a movie. I believe it might be some kind of overheating problem but would like someone to confirm this.

Most likely your problem is on the DMD Assy Board P/N BP96-00249A . More presicely there is a few bad electronic components on that board that are bad. That board can be repaired by replacing the bad components (and the other few compoonents that are probly going bad and will soon cause your tv to lockup and lose remote and button functions when it fails so you will need to unplug it to get it on again).
Or the DMD board can be replaced .But it is not a cheap board.
For removal and Installation of the DMD board I would reccomend a tv service person because it is in the heart of the television and there are some adjustements to be made when the new board is installed.
To get the new board you could probably find it by just gooogling the part number.
Component level repair would require some experience in desoldering and soldering SMT,SMD , and or surface mount components.The actual components are about $15.00 total so just repairing your board should cost about $125.00 by a qualified servicer (if you were to remove and install it yourself). This DMD board is used in many models and can a few common problems.

SYMPTOMS:
-Intermittant picture freezing with a negative looking B/W frozen picture.
-Intermittant loss of pic with/without shutdown,abnormal color wheel noise if attempted to start after shutdown.
-lockup of tv control functions . Remote and front keypad do nothing , TV must be unplugged to reset .
-horizantal tearing, distortion , flippnig , solarization , red picture, leading to blank screen and lockup.(tv menu would be affected by all picture defects).
Hope this helps someone..
