Fragged RCA F26020WN

Well, as I said......the set had been on for several hours straight and I had sorta dozed off.....this TV probably has never seen this much continual use in it's life......I was awoken by a kinda pop noise and opened my eyes only to see a raster as pictured above.

Can cold solder joints exhibit in this manner? I mean can they just go "pop" like this? My feeble knowledge leads me to believe a component failure is more likely. Hopefully some of the resident RCA experts will share their thoughts on this. Thanks
