[TechAssist] Re: Toshiba Md# TP50F61, TAC9675

Thanks for the feedback Al, I took a third look and I don't think that's my 
problem.  I'm 
thinking maybe the driver Q719, which is a TA75559P different than the other 
two which are 
Motorola chips.  Although I'm not quite convinced that the driver would allow 
the red to 
adjust up/down and not left/right. In the convergence menu with the grid on the 
screen red 
is acutely bowed in from both sides. I'm also thinking it could be a bad or 
corrupted eprom 
Q713...
I could really use a schematic and parts list here if anyone has one.  
Otherwise I'll call 
Toshiba on Tuesday and see if I can get through to technical.
Thanks again Al, much appreciated.

  I am not sure of the model but I recall a toshiba of about that vintage
where one of the traces that goes by a large ground trace below the heat
sink for the STKs was either open or had carboned the board over the the
ground trace causing a short. I replaced the STKs twice before I found
the short.
