Re: Older flat screen pioneer . Keeps shutting on and off...
Sounds like power supply issue.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary
Sounds like panel fault. Check this site. There is screen shots to many faults that occurs to Plasma displays. Compare them to that of yours, and get confirmed. Pull up older posts there. Check the site with patience. More than 2000 post are there, and all are related to repair help to electronic entertainment and domestic equipment.
Since your plasma is less then a year old, I would suggest to contact the manufacturers to get it fix under warranty. If the plasma keeps shutting off by itself, that is not normal and should be repair.
We are having the same problem of the Pioneer Elite Pro-99 turning itself off all of a sudden. The red 'non' power button comes on as if we had turned it off remotely. We would love to resolve this. If you can help let us know.
Did you try alignment of color convergence in setting up. Try this
1 Press MENU
2 Select SET UP
3 Select CONVERGENCE
4 Select screen mode ZOOM this accesses the center convergence adjustment.Press set/enter
5 Use arrow keys to aline the red cross to the white cross.Press set/enter
6 Use arrow keys to alingn the blue line in the same manner. Once adjustment is complete press MENU to turn the menu off.
I hope this helps if you cant move the red or blue lines you face the same problem I face. I still havent gotton any solutions to my post about being unable to adjust the red line.You could also call Pioneer's help line 800-421-1404.
I hve worked on a number of these units , your description is typical of a shorted blue picture tube. The protection circuits in the tv
detect that there is a problem thus shutting the unit down to prevent further damage. Sony had a bad run of picture tubes in this series.
The replacement cost of the tube is about $250
plus labor. My estimate would be for the repair
about $400-500 depending on where you live and how honest your local technican is. I will caution you however, that you could replace this tube and the red or green could go. These would not be covered by the technicians warranty. When these sets are working, they have a superb picture and it is easy to get lured into fixing them. Scrivitron
