Convergence issues with Toshiba 42H83 - Red lines will not align


Absolutely! if the consumer control has failed to rectify the problem you need expert help. There are two control boards near the power supply 1 or both are involved and more than 90% of the time both of the boards have to be replace otherwise the problem will occur again in a short time.
It is not a DIY project for the unskilled as it has to be tuned correctly when it is installed.
Better to leave it to the professional

Will not 'Touch Focus' - Toshiba 42H83


1)I have yet to learn any advantage to replacing -110's with -150's
I think there is a misconception that increasing numbers =
better,more durable results....Actually, using OEM or better
quality should be most important.Generics from any source
tend to be seconds,thirds, junk ! Name brand are first quality
2)Check B+ feed resistors next to convergence IC's = burnt ?

3)Solder wire jumpers on signal board = 008,010,017,600,etc.
prevent maitenance
