It's simple. Your TV does not like you. Perhaps you need to speak kindly to it before you force it to watch BBC for hours. Buy it a scone.

I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

Since you have another TV with the same problem you can try using an antenna(indoor model ok) to see if the cable is causing the problem. If not return TV before the warranty expires.

Samsung's have notorious problems with their lens-cap shutters malfunctioning. This seems to be the case with yours. It will have to be serviced, I'm afraid.
