TV screen goes blank just after switching on; volume stays on. After examining circuit boards, discovered immediately selecting menu then reset to default my screen operates perfectly until off.

It sounds funny but, unplug the set for 30 seconds to allow the TV to reset then see if the problem still is there.

1. You would press and hold stop on the front of the unit for 5 seconds then let go and press it again normally, you can try this with both the power of the unit on and off.

First suggestion is to unplug your unit for 24 hours, if does not correct your concerns, you may have fluid leakage from the tubes onto the pc boards. Make sure you have proper air venting around the tv. If problem persist call factory authorized dealer in your area. good luck

Hi dogbyte,

For some reason, certain Windows Mobile (Standard) devices don't like "list" format for the Start Menu.

Give this a try:
1) Remove the battery for 1-2 minutes. (This allows any cached memory to clear)
2) Power the device back up.
3) Before openning ANY other apps, navigate to Start > Settings > Display > Start Menu Style
4) Change this value from "List" to "Grid"
5) Click Done twice, then click the Home key.
6) Give the Start menu another try. (Does this resolve the issue?)

Another forum suggested that Windows Mobile seems to be a little picky about which application appears first on the Start Menu. If you have any custom applications installed, it's possible WinMo's start menu just isn't playing nicely.

Hope this helps!

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:
