      If the Sharp TV fuse is blown, replace it. If the fuse blows again, check the voltage at T701 pin (8), which should be approximately 310V at 220V AC. Also, check NR701, IC701, D701, C705, the CRT connector K-circuit, IC751 for the 3.3V regulator, Q601, Q602, Q803, and the signals at various pins of IC1001.
