Ok, I figured it out -- it's a VO370M not a V0370M -- notice the difference?
Looks like we need your serial number off the tag on the back of the set too...
Now, there is one thing I need to verify with you....
When your TV goes BLANK...
Do you still have the sound coming from the TV set? Or does it also disappear?
Can you still activate the TV's menu and see it on the screen when it's blanked out?
How about the screen itself....does it look BLACK or is it "gently lit up" ?
I need to know this information so I can determine if your Backlight/Lamps are turned off, or if they are turned on.
There are two possible boards causing your problem, and if the LAMPS are going black, we replace the inverter.
If the Sound stays on, or if the MENU still displays, then the main board is the failure point.
Get that information, and I should be able to tell you what you need to repair your TV set, ok?
