Sounds like a problem with source recognition. Could have a problem with input coming into the tv such as cable connection problem, loose wires, etc. Try reseting the cable box and removing and reinstalling all of the cables in the back and the cable box.
Reset the cable box,by unplug,replug it an hour later.So the box will upgrade it software.Should work after this.Not,there a HDMI cable,U use this cable.Replaced it.Don't work,after this,take another tv test the tv incomming signal.See,if the cable box is the cause.Not,than ur DLP tv Main Tuner board is dead,must replaced to solved this problems.
This sounds to me like one of two possibilities. First, check your ballast. If you're going through bulbs faster than you think you ought to be, you may have a ballast that is overloading. Its the 3" x 8" circuit board that connects directly to the bulb. They are plentiful and often cheap. Thats what I'd try first. If that doesnt' do it, I would invest in a new power supply board. That the board that the tv power cable hooks directly in to. This should give you a start, Comment back if you still need further help. Good luck.
