HELP PLEASE Vizio Plasma tv broken again - possible driver board?

Our Vizio 50'' P50 HDM Plasma tv is about 2 yrs old or so. Out of warranty and trying to deal with Vizio is a nightmare.
Last month the tv made a very loud cracking noise, like the snap of a whip and the color went out of the picture. It got very fuzzy, but you could still see some picture on the screen. We took it to a local repair shop who charged us far too much to replace the driver board. Worked fine when we got it home.
Last night it made that same cracking noise twice and now we get no picture whatsoever. No menus... Black screen. When you turn it on it makes the quiet humming noise like it is trying to turn on and then the power light flashes and goes to orange.
Any idea what could be causing this and if it's something we can fix ourselves? We can't justify spending another $400-500 to take it to a local repair shop just to have more trouble in a few months, especially considering the same model is only $1000-1200 new. But we really don't want to have to replace it!
We're somewhat handy with these things - just replaced the lamp on our dlp tv a few months back. But, not sure what to look for if we opened up the back of the Vizio.
Any help/advice/ideas/etc. would be greatly appreciated!

    When you turn it on the led light turns green and you can hear the hum of the tv starting up like normal, but then it goes quiet, the led light flashes and then turns orange. There is no picture. The first time we tried to turn it on after the popping noise you could see a flicker of grey on the the screen and then completely black. You can't see any menus or switch between the cable box/dvd player
    You can't shut it off without unplugging the power cord.
    Any ideas?

    Can the TV turn on? What is the color of the LED? If it can turn on, can you turn it off normally?

This could cause by the power supply or the mainboard.

- If the LED stay Green when you turn on the TV. But you can not turn it off, in this case the main board has failed. Replace the mainboard will fix the problem.

- If the LED light always stay at Orange, you can not turn on of off. In this case the mainboard also has failed.

- If you turn on the TV you will hear the power supply click on the LED is green then it click off the light turn Orange. In this case the power supply has failed.

Which boards did the repair shop replace?

Hope this will help.

I have a Vizio P50 HDTV20A. A couple of weeks ago our dvd player and WII system stopped working on AV1 or AV 2 - tv shows "no signal". The WII and DVD player work fine on other tvs. Before this...

Hi, if you plug up your cable box the AV1 does it still not work. Please let me know what you find out. If you take of the back of the TV there is a reset botton on the main input board. Thats the board where you hook up your devices too. Please let me know if that works or not.

I have a Vizio P50 HDM and while watching it last evening I heard a loud pop and the picture went into a very noisy/distorted condition. Sound is OK. Any ideas?

That loud pop is your Y and Z sustainer. Normally it goes out completly but yours is still half working. Not usally fixable yourself, because you may need to flash the control board f/w , which is proprietary and can't be aquired unless you work for them,

Sounds like a bad power supply. I have a GV42L 42" manufactured in march 2007. It works perfect except the screen has a fracture on it. The warranty is voided because we damaged the screen. I can sell this to somone who has a good screen but needs boards or speakers, etc. Or I will buy your tv that has a good screen but damaged boards in it.

Visio P50 HDM television

Well, I have the same problem - I have a Vizio P50 HDM that died after 16 months of use (1 year warranty). I called Vizio and they gave me the number of their authorized service company. They told me that it was the YSUS board which would have to be replaced with the ZSUS board - $835.00 visit including parts. That was three months ago and they are still not here. This is a common problem - Do a Google search for the "Vizio Pop of Death". It seems most are not repairable and have to be replaced. Now I have a $2700 wall decoration. One idea might be to do a search on Ebay for the part number - More and more are showing up on Ebay from units with cracked screens - Good Luck. I was a component level TV tech for 20 years and will do this myself, probably with parts from Ebay. Some say they have had success taking it back to Costco or Sams, even after two years - If you got it at one of these stores, it wouldn't hurt to try.

They tell you to unplug for 30 sec. Plug back in and hold powerbutton when replug... it doesnt work. Get kicked up to level 2 support... problem solved... as long as repair works...
