It seems that you have good power, so that shouldnt be the problem, You should go in and inspect for any swollen capacitors - they will look like the top is bulged outward..this sounds ALOT like a capacitor problem (rolling screen) - also if you have a problem with the inputs shutting off and giving a blue screen, you need to replace the 9v regulator on the main board right behind the signal board - it is a surface mounted BA09FP regulator... Let me know how this goes for you!

So far I pulled the DM,those caps look fine.Will check rest of boards tomorrow.As far as the blue screen goes,it's not a raster,it's the actual background of the menu,it's just the icons are all jumbled at the top of the screen.I'll let you know what I find on the other boards.Thank You for your help!

Merry Christmas!! Here's an update.I removed the chassis tray and disassembled all the boards.There were no swollen or leaky caps,or any noticeable cold solder joints at all.I removed a LOT of dust and put it all back together.It is still having the same problem.If I goto the device menu screen,I get this.
Great stable view with no roll.If I set it to Ant A,or VCR,I get this:
Dark screen,no audio.If I turn all the way up,I hear a slight pulsing,and the screen appears to have some light to it,but no picture.
If I set it to any of the card inputs,or the digital antenna,I get this:
I've also noticed that although everything works off the remote,the front panel controls don't do anything.I'll look into that later.Thanks for any help you can give.

One last thing.There is a yellow with green stripe wire hanging down from the CRT board.It is tied with all 3 guns to chassis grounds up there.It is a 2 wire plug marked PX(I think,I'm not there right now).Anyway,I could not find a socket for it on any board.Is this for a degauss circuit?Is there a certain board I should narrow the search to(Power,DM,etc.)?Thanks again for a very informitive site.Onec I get this one nailed,I may be tempted to fix the other 4 people have given me.God Bless!
