It has all the details, schematics, boards, voltages, troubleshooting table etc:- If the IC i stated above is faulty, you may have to replace the main board of the TV.

May be you went to the wrong place, find another repair shop where they work that brand and type of tv. Doubtless, some parts are discontinued, but they will take parts of another equipment that are dismantled. Good luck.
