Riddled TV Repair Forum

I bought this TV recently off Craiglist for only $25, they did warn me that it had "once" turned on to no picture, just sound. Sure enough, that happened almost immediately once back home. A little whack on the left-rear did bring the picture back one time. The item located in the left-rear, from which emanate 2 thin red wires, 1 thin white wire, and 1 much thicker red wire which goes to the picture tube seems to be the problem. I have (foolishly no doubt) cut out a 5"x5" area from the plastic cover in the back, and a very quick nudge to the thick red wire will often bring the picture back (after a small 'pop'). However, if the picture goes out a 2nd time, nudging the wire doesn't help.

Is replacement of that entire part possible? I can have a friend investigate for free ; however there are many similar or larger HD ready TV's on Craigslist for $60-$80, so spending a lot for a part makes little sense. Thanks for any input.

flyback transformer. That Pop sound is high voltage dissipating to another part of the circuit... which is pretty dangerous. replacing the flyback is not a big deal if you can solder, but I haven't priced the material cost.
