Television and Home Theater

i just plugged in my tv after not using it for 3 years.  it worked great for a few hours then got color lines, the sound got really loud (i didnt turn it up) then the tv turned off.  when i try to turn the tv on the green light is steady for about 1 minute (no picture no sound) them turns itself off.  i pressed the menu and input and got a 2:3 code.  what can this be. 

I've determined that the 9V regulator (IC9C25) needs to be replaced.  I need instructions on the procedure for replacing the IC.  I've seen posts concerning the replacement, but no instructions.  I have the manual for the TV. but it doesn't go into any kind of detail for the procedure.  If you have the procedure, please email it to me [email protected].

Hi, I've read most of the other posts both on this forum and elsewhere, but haven't just gone and got the convergence repair kit yet since I'm not sure that is it.

I checked all the fuses and they are all good. Even F860 (bad cap solder), all the F85X fuses, etc. My cheap multimeter is not good enough to check the adjacent resistors next to the convergence chip.

The TV intermittently started to get the blinking light, but after cooldown it would start up again. Now, its totally dead.
