Hitachi 51S500 "dry joint" problem? Please help!

[rootsgroup]

Picture will go from great, to slightly splotchy, or gross red streaking, or just black. Sound remains in all situations. Tapping the cabinet even just lightly will change the picture from/to any of the above situations. Somebody walking across the room in front of the set can even have an effect.

From cold start up, tv is ok for the first 5 minutes, then gets real fussy for 90 minutes or so, then seems to calm down pretty much.

Based on the above, I'm convinced I need to be looking for a bad solder joint or loose component. Can anyone narrow down this humongous search I am about to embark on? If any more info would be helpful, please reply and I'll try to come up with it.

Build date is 9/03.

Thank you,
