You Tv has a bad chip ( I recommend you replace both on the convergence board ). 80% or more of the projection sets I get into my shop have this same problem and by replacing the convergance chips, it normally corrects the problem. If you are going to preform the repair yourself, be sure to use lots of heat sink grease to prevent the problem from happening again and I always suggest you use the original chips ( same numbers ) as the after market parts don't always work well. As a pre caution, always remember to unplug the set before doing any work inside the set. Good Luck

Hdtv with yellow half circle on bottom of screen

Odds are real good that the cooling fluid in the blue picture tube assembly has become contaminated. Only solution is to pull blue crt and dump out old fluid and clean and reinstall new fluid. Once done a fair amount of re-alignment is required. This is not a job for a do-it-yourselfer. Most tv shops would charge in the area of $250 to $300 for this repair.

The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
