Here we go again with rip off repair shops ..
getting the chassis out far enough to get the board out is quite a chore
you have to take off alot of wires/plugs .
If you can solder `very well` that may be all it needs . It would be
hard to get shocked in a big screen tv set doing a convergence board .
If you cant try to get help taking it to a reasonable repair shop to
avoid their 100$ travel time .
