Hi- We have a 50" Samsung DLP hlp5063w acting strangely. First we lost the picture, audio only and it wouldn't turn off. After unplugging/replugging it seems to try to turn on automatically, but shuts down after awhile. When it finally would restart, it's audio only, for less than a minute and it shuts down again. Sometimes every light on the dial is flashing. Now it won't even start unless I unplug and replug it in, then it comes on automatically and is fine! Last month we had picture problems, I replaced the lamp and we were good until now. I'm getting very frustrated...
Ensure that the TV is off. It may be advisable to unplug the TV as well.
2 Using a Phillips screwdriver, remove the single screw affixing the lamp cover (the small, grill panel on the back of the set) to the chasis. There is also a grill that is held in place by tension. Just "pinch" the thumb clamp on the bottom of the grill and slide it out. This is the same procedure you would perform to change the lamp, except in this case you will not need to remove the lamp itself.
3 Inspect the spring-loaded blue safety switch to ensure it is making good contact when the panel is secured. The switch should deflect downward when the panel is replaced. If the contact with the panel is suspect, very gently bend the metal bracket on which the switch is mounted.
4 Replace the grill cover and the lamp door, and continue to enjoy your TV.
5.Check some basics first. Make sure the sleep timer on your TV hasn't been turned on, telling your set to turn off at a certain time. If your DLP TV is acting erratically, Samsung recommends turning the set off and unplugging it for 30 minutes. After 30 minutes plug it back in and turn it back on. Unplugging the set resets it, and that may fix the problem.
6 Check your power supply. Make sure your Samsung DLP is securely plugged into a working outlet. Plug the TV into a different outlet to see if the problem still exists. Make sure that a fuse hasn't blown in your house or a circuit breaker hasn't flipped.
7 Replace the lamp. If your Samsung DLP is shutting off or won't turn on, a bad lamp is the most likely cause. To replace the lamp, remove the lamp cover from the back of the TV by removing the screws with a Phillips screwdriver and slide it out and away from the TV. Remove the screws on the lamp assembly and slide it out of the TV. Disconnect the old lamp and insert a new lamp into the assembly. Slide the assembly back into place and replace the screws. Do the same for the lamp cover.
8 Check for signs of overheating. Samsung DLP TVs generate a sizable amount of heat. If the components inside the TV get to hot, the TV will shut itself off as a protective measure. Make sure your DLP is out 12 inches or so from the wall. Make sure that all of the vents on the set are clear of any obstructions. Allow the TV to cool down for 30 minutes before turning it back on.
9 Contact Samsung. If none of the above tips help, it's time to contact Samsung, as the problem is likely something that should only be fixed by a qualified service technician. More serious problems may include a bad power supply or a bad ballast. Attempting to repair those yourself will void your warranty and may cause more serious damage to your set.
The safety switch exists so the user does not accidentally remove the lamp door while the TV is on. Doing so could, theoretically, result in burn or electrocution. This spring loaded switch causes the TV to shut down when the door is opened.
Since the TV's chasis is plastic, expansion and contraction can cause the switch to lose firm contact with the lamp door. The TV's behavior could then be such that after being on for a while (getting warm) the plastic expands and the switch loses enough contact to cause the TV to shut down. The frequency with which this phenomenon occurs is not only dependent on the internal temperature of the TV, but also the ambient temperature of the room as well as the relative tension on the switch itself. The user's perception is that the TV starts up fine, but then "randomly" turns itself off after being on for a while.
If you have recently moved your TV, it is very common for random shut-downs to occur. This is because the move has shifted the flimsy plastic chasis of the TV, thereby loosening the contact between the lamp door and the switch.
Make sure your TV is off and cool when performing this procedure.
Along with the above mentioned. You can also try this as I did and it worked.
50" DLP from Samsumg. HL-P5063W. I had the same issue of 3 minute shut off issues. So I found this step somewhere on the web. This step has did the trick and has not shut off again.
NOTE: You will have to re-set everything as far as your sound, color, Picture quality ETC. AFTER this step.
This is a quick reference guide to show you how to reset your Samsung DLP TV’s lamp hour meter or hour counter. Resetting the counter is a very simple proceedure.
HOW TO RESET YOUR LAMP HOUR METER:
Begin with the TV powered OFF.
Point your remote towards your TV.
Press:
Mute 1 8 2 Power. Buttons pressed consecutively but as fast as you can and NOT same time.
Your TV set should now say “Loading Factory”.
Browse down to “Option” then press Enter (or the right cursor button).
NOTE: The Mute 1 8 2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterward!).
Wait atleast 30 seconds. I sure hope this helps many of the folks out there. If it did/didn't please post reply.
I am NOT endorsing this method. Use at own risk. But did work for me. As easy as 1-2-3.

Hi Iverish-
Last month I had our cable provider company technician in, he said the signal at the TV was weak, so we ran new cables and I removed the Bose home theater system and the old VCR from the circuit. We also replaced the digital cable box. That upped the TV's operational success rate to about 90%. As per your instructions I removed the back cover, however the style we have is held on by 4 screws with no metal contact. I inspected the blue safety toggle switch, giggled a bunch of wires and contacts and replaced the access door. I also increassed the air flow around the TV. So far the TV has started and stayed on every time, but its only been a few days since all this was done. THANK YOU for your expertise! Todd
