TX-52F480S lines after watching for a few minutes, sometime up to 30 minutes, colored lines start popping up and won't go away. in half the case, after unplugging the power cord, waited 30 sec or so, plugged back in, it would work. then the lines would re-appear after 5minutes or so

Your problem is in HOT, Horizontal output transistor is defected already ,this is high voltage transistor , if no high voltage there no picture ,but supply is there because light is flashing ,the supply voltage is trap ,when this voltage go to horizontal section your tv is automatically shut off because defected HOT,,you change this transistor ,so performance will better again ..find a tv repairman to do the works in changing the transistor and little reheating works.
This is better in order to avoid high voltage shock,this not cost much....

SOURCE: TV appears dead

SOURCE: My TV is 2 years old and the picture colors change

Bad LCD controller (the cover is removed in the picture), see sample here: http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/

There are more than one version of the board, you need to match withe the LCD panel number.

Testimonial: "I would like to thank you for your expertise. The solution you suggested was exactly what the problem was. Also thanks for the link to the parts store. It took me the better part of a year to work up to tackling this one as it had been more than forty years since I repaired TV's. Anyway my TV is working again and the wife is happy. Again, many thanks Dennis"

SOURCE: Good picture for 30 minutes then colors change!

Bad LCD controller, see sample here (note, I removed the cover off the board so you can see it): http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/

Be real careful when you remove the back cover, the side switch assembly is attached to the back cover, so do not yank it too hard!
