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?

Disconnect the power cable from your projector. Allow it to cool for 30 to 60 minutes. Lay the projector upside down on a table.
Remove the lamp
cover, typically located on one of the rear corners of the projector's
underside. Depending on your projector, you will either have to loosen a
few Phillips screws or press on one or two plastic release tabs to
remove the lamp cover.
Loosen the screws holding the lamp assembly in place. Grab the assembly by the handle and slide it out of the projector.
Slide a new lamp assembly into the projector. Don't touch
the glass on the bulb because it will damage the bulb. Tighten the
retaining screws on the lamp assembly and replace the lamp cover.
Turn the projector right side up and reconnect the power cable. Power on your projector.
Unplug the TV from the outlet. Let it cool for 30 to 60 minutes.
Remove the lamp cover. On most rear projection TVs, the lamp
cover is located on the right or left side of the TV's rear panel.
Remove the cover by loosening the screws and pulling the cover away from
the TV. Certain manufacturers, like Mitsubishi, have the lamp cover in
the front of the TV, near the left speaker. To get to the cover, you
must first use your fingers to pry off the front panel below the screen,
revealing the speakers and lamp cover. Loosen the screws on the cover
and pull it away from the TV.
Remove the lamp assembly. Loosen its screws, grab the handle and slide it out of the TV. If you have a newer Sony model, there are no screws. Instead, press the release tab to unlock the lamp assembly and slide it out of the TV.
Slide a new lamp assembly into the TV. Don't touch the glass
on the assembly, as the oils in your fingers will damage the bulb.
Tighten the screws or pop the retaining tab into place.
Replace the lamp cover and front panel, if necessary. Plug your TV back into the electrical outlet and power it on.
Tips & Warnings
Touching the lamp assembly before it has cooled can cause a nasty burn.
Suspect your POWER SUPPLY. Either your supply is faulty OR something else in your TV is demanding too much CURRENT (from the supply) and your supply may be 'protecting itself' with 'emergency shutdowns'.
These links and PHOTO WILL help you ~ if you are serious about repairs!
I know it's not quite the same model number as yours, but the steps and efforts remain similar.
Finally, this REAL 'old puppy' that DEMANDS LOTS of AC POWER to fire-up your 3 'super-bright' projector lamps inside! Are you sure you won't consider pushing this TV to the curb instead of investing HOURS of your life to fix this one?
I'm confident you have spent LOTS MORE on your POWER BILL (over the years) than the cost of a NEW Flat Screen model! GO ahead ~ you deserve a quality TV... but stick to known brands like LG - VIZIO and Panasonic to avoid the "no parts/boards available" problem (way down the road).
*(Your TV is so old that the Internet has NO CLUE when they first made this model)*? Also I see a whole ARRAY of problems with this series and it's no surprise that yours has similar problems!
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.........
