first of all i would like to know your Unit.. this is CRT TV type or LCD TV? ok well'' if this is CRT type did you check B+ line Volts? 100vdc? did you check HOT mean horizontal output transistor. now cause of high voltage shutdown check t out B+ line when its goes up, this the cause of your hgh voltage shutdown means you have no seen light up to filament... and also check the E-capasitor has capasitance 100uf 160vdc and chec the risistor going to the B+ when its open... hope this can help. just update me sir

Google the units model number or zsus or ysus. Should find at least one hit that tells you what type of set (Plasma). Surprised
