Mr Ong the technician that I contacted last night, came to my house this morning to check my tv. He opened up the huge tv box at the back and then used his multimeter to test the set. It took him about 15 minutes then he suspected the IC problem. He then took out the whole mainboard, detached it from the CRT and the tv box and brought it back to his home. He said it would take one day to get the part and install it. So the tv box and the screen were left at the rack like a cleaned fish without its inner organ.
