Question about Vizio P50HDTV10A 50 in. Plasma HDTV
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!
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.
