on a second look, I think the capacitors are correct, so now I guess my question would just be whatever tips you guys might have for soldering, as in type of soldering iron ( mine is just a basic weller with no temp control dial) and whether it is ok to just use some radio shack desoldering braid for desoldering and cleaning up my joints.
Replacing parts on printed circuit boards that you want to work properly when done, is not the best way to go when you are also to trying to learn how to solder. Might be a good idea to find some kind of junk printed circuit boards, to practice removing and replacing parts on first. Unsolder some parts on them, and then solder them back on. Either that, or pay someone you may know that is experienced at soldering parts on circuit boards to do it for you.
Solder braid would work, though is best used to remove/clean old solder after the component is removed. I would use even a cheap solder pump(vac) rather than braid by itself. If the pads are corroded from leaking electrolyte, clean them up with a toothbrush and iso alcohol. Make sure your caps are being replaced at the same polarity, use a clean, sponged and tinned solder tip, rosin core solder or separate flux.
As per the above post advice it would be a good idea to practice desolder / solder on and old pcb if possible.
Im just a tinkerer, not an expert so keep that in mind if you use my advice.
The bad news is that for all those caps to fail it would seem likely that there is some other component with a short causing the problem. Caps are cheap so I'd probably replace them with hope, however stand clear when powering keeping safety in mind as they could fail again violently spreading corrosive electrolyte.
** I dont know what other's situations were with bad capacitors on the PS board (that you referred to) and if replacing them fixed the problem or not, but after seeing your picture of the AC supply combined with the large number of swelled caps, I'd be REALLY be leaning towards the opinion that is just the byproduct of a different problem. Again, however, caps are cheap so its worth a shot.
It sucks that this P50 has such a defect but I am glad based from reading the comments that Vizio is willing to help fix the problem. I hope everyone that has this defect has good available options to choose from in dealing with this issue.
i tried to unplug it and hold the power button for 30sec but no luck.
1. am i in the right thread?
2. if so, any ideas before i dig into it and start playing with the voltmeter?
Does your set proclaim "no signal" when you have it connected to a video source like a DVD player or does it only do so when you're trying to receive a signal directly from an antenna or cable source (without a separate cable box)? If the problem occurs with all sources, then the problem is probably with the input board. If it only does so for TV stations, then it's the tuner.
I'd check with Vizio and see if they have authorized repair in your area. They might fix it for a reasonable price, or you might be able to replace the affected board yourself. Just remember, a 50" 720p plasma like the JV50 only costs about $600 now.
to answer your question, it says no signal in every mode except tuner which just gives a blank screen.
You need to be VERY careful poking around inside of a Television set. Unlike other electronics there's things that could potentially kill you inside and you're not too far from them with what you're working on.

My daughter fell asleep with the Netflix login over night. I now how red burn in on my screen. I have had my PD50HD for 5 years and I haven't had any problems. I ran the screen image cleaner and it helped, but after a few days it comes back. Does anyone have any suggestions?
This works well for me:
I'm just checking in to let anyone who is still lurking know:
My Vizio finally died about a month ago. Just like all the earlier ones, there was a loud, sharp SNAP and the picture was gone.
I guess it's time to replace it, but the sad thing is that the newer sets don't have the features I've come to enjoy, like Picture-in-Picture. Most sets have only one analog input, so I guess I need to replace my DVD player, too.
I mostly watch over-the-air, so I'd like a TV that does a good job implementing the program guide, but neither the manufacturers nor the reviewers seem to have any information about it. The instruction manuals don't even mention the program guide. I have a small Samsung that completely implements the guide, but accessing it is very clunky and annoying and requires numerous button presses on the remote.
...and I definitely want another plasma.
Anybody got any suggestions?
This exact thing happened to mine. But I don't get anything on the screen.
Front LED will turn from amber to green when I press the power button.
I hear 2 clicks on the power supply board when I turn the power on, & 1 click when it is turned off.
No picture or sound.
Blinking green LED on the power supply board.
Replaced all of the caps, even the large ones. Replaced the fuses.
Anyone care to point me in the right direction? Anything I can check with a multimeter to find the problem?
