Question about Vizio P50HDTV10A 50 in. Plasma HDTV
My Vizio will not turn on. If I unplug the TV and then plug it back in, once the power button is pushed, the fans will come on followed by a couple of clicks and then the TV goes off with out ever having a picture come on. The second time trying to turn the TV on, on fans or clicks and no picture.

You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

You have faulty electrolytic caps in the power supply section of the tv. Capacitors with reduced quantities of electrolyte take longer to charge compared to normal ones. That is the reason its coming on after you repeat the on/off sequence a few times. If you are not good at soldering, replacing the power supply should do the job. It should cost you about 75-100$. Let me know if you want to do it yourself(please get me the model number of the set as well so that I can find you a replacement).
