So just today the picture began "bulging" to the right and distorting intermittently. I later turned it on and found the picture to be half way off of the screen to the right... after leaving it on it centered itself after 5 minutes or so but continues to "shudder" and "bulge" to the right.... any thoughts or is it just in need of an exorcism? ;)

This is a problem (one of several) caused by poor solder connections on the circuit board. RCA uses the metal shield can surrounding the tuner circuitry (the area where the cable connector is located) to provide several ground connections. Many of these connections go bad (cracks form) and the missing ground connections cause the "picture shrinking" you see. Other problems are loss of tuning, set that intermittently turns off or on by itself, set that won't turn on at all, and even more.
The repair involves removing the circuit board and flipping it over so you can remove a metal cover on the bottom, repairing the several (many) affected connections, and then reassembling. This is a relatively easy repair for someone with soldering experience and the right tools (both a high-heat soldering gun and a low-heat iron are needed). But because of the fragile circuit traces in the repair area it is possible to do more harm than good if you don't know what you're doing.
RCA produced a service bulletin several years back detailing the areas to be repaired (although they still refused to admit they just hadn't soldered the places adequately to begin with). I'm not home now so I can't check my files but I'll see if I can find a link and add a comment later. When I was in the service business we charged around $60 for the repair. You might want to get an estimate from a shop (they should already be familiar with this trouble). Or if you're looking for a reason to buy a new set, try the repair yourself. If you're successful you've saved yourself the money. If not, it wasn't working anyway!
I would suggest to locate a part that looks like the one on this link and re solder all the pins, also check for any high power resistor nearby the IC295890 and put some fresh solder.
Let me know if you need further assistance.
ok,try to resolder or reheat the main board of your tv.from microprocessor,the video chroma section,the crt board...if reheating is not the solution,replace either the microprocessor or the chroma or crt driver.
I suspect you originally had an intermittent solder connection on the convergence circuit board. This may have damaged the convergence IC's on that board by now if repairing those connections doesn't fix the set.
