Hello,
I think I still need help on this. I have light box here right now using the
ceiling, but it looks like the convergence is stilled bowed.
I replaced the two STK392-110, R4162, 4163, 4161 and R1460. R4160 and R4161
gets extremely hot to touch. The convergence looks better, though at the top
left corner, all colors are bowing downwards.
On pins 6-14-15 of STK's I have no, or less than 1vdc on each. Is this
normal?
Thanks to all that have helped so far
Jeff
