I have a mitsubishi 60 inch RP that has a pin and barrel issue, only its occurring at the top and bottom of the screen instead of the left and right sides where I normally see this issue. I suspect horizontal output transistor may be failing.. but not sure. The blue CRT is out as well. TV was working great the night before and now it is having these issues all at once.

try cleaning the lens & mirror, there may be something in there. other wise may need a new light engine. If the light engine is what's causing the issue, recommend replacing the TV with a NEW LED or LCD TV, due to costs.
CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
These are fairly simple, remove the speaker cover and then remove the screws at the bottom of the screen, then the whole thing lifts up and off, be sure to unplug the front panel controls, this plug can usaly be found just behind the cover behind the speaker grill
A can of compressed air might do the trick. If dirt is stuch, I'd suggest useing the same chemicals/cloths/etc you would use for cleaning camera lenses. Check at your local photo store.
Just make sure the lenses aren't hot when you apply cold and/or flamable chemicals.
Have convergence IC's changed in your 60" TV. I only use ORIGINAL IC's, not generics or knock offs. Most companies that fix have no idea what the difference is.....
