Would like to know where to purchase the power supply for this TV, also need to locate instructions on changing it out. I'm sure that is the problem, it shut off by itself, and when trying to turn back on sounds like a heart beat with no luck turning back on. I like this TV and would like it back up n running w/o paying a technician. Believe I can do it with instructions.

Re: RCA P46924 46" Rear Projector TV
First of all, we need to determine whether the power supply has a problem or if it is being told to shutdown because of a problem detected in the set. Are you familiar with electronics repair? Do you have a meter?

U DM power supply board have dead capacitors,before the capacitors have some functions left,that why u able to recycles by pushing the power buttons 3 or 4 cycles to get power to the tv.U have tools,soldering iron,solders,and know to do soldering?Tries website like Tvrepairworld.com to buy a capacitors kit,that design to replaced in the DM power supply board.Look around and replaced these dead capacitors,it alway bulges up or puff up on it top.Ur tv will power up and as normal again.
That can either be the Flyback or the HV splitter. The flyback is located on the lower left hand side when looking in the rear and has a large red cable coming out of its top. The HV splitter is located in the front in the center of the set. These are both very easy and inexspensive to replace. I can post a link where you can get replacements with instructions.If you would like.
MOST LIKELY, THE PROBLEM IS THE BULB USED IN THE SET? BY THAT I MEAN THE HIGH INTENSITY REAR PROJECTOR BULB? DO A SEARCH ONLINE AND THERE ARE COMPANIES SELLING THE BULBS AT A PREMIUM. YOU MAY WANT TO CONSIDER DUMPING IT.........

For the majority of phillips/magnavox universal remotes: Hold code search button down till red light satys on. Press the tv button and the red light should blink and stay lit. With the tv on, push the power button repeatedly until the tv turns off.(dont push the power button again after the tv turns off or it will go to the next code). Push the mute button to save the setting.
