Question about Toshiba 40H80 40" Rear Projection Television
had tv since oct 2000 ......couple of months ago on switch on had the odd grouping of what appeared to be flyback lines but only in small area of screen [not all the way accross].....this problem did not show all the time.intermitant.....ABOUT 4 days ago this problem disappeared and now the tv has a bent picture DOWN at bottom left...bent UP at top right of picture........this means that the RED and BLUE are out of syncronisation by as much as 1.5 inches ie showing a blue and red picture outline......the centre of pic and top left and bottom right still appear okay.....normal convergence adjustment will not sort this........shame to get rid of...tubes /guns still good and strong.......pic still very good ...........HELPPPPPPPPPP
Convergence IC's need replacement = STK392-110 original #...
Use name brand Toshiba, NAP, or upgrade to STK394-160E
Hitachi part # CZ 01341...no cheap generics..they won't hold up..
Chassis pull and some precision soldering will be needed....let me know if you need further info...........................T.
