The first Sony colors were not bad. The only thing odd
about them was they used separate HV & H sweep stages.
They switched to an SCR the SG613 abt '74 & they were
dogs to deal with. I did time at Sony service in '76 IIRC.
Even they couldnt reliably fix them. Most of them got the
whole H/V/HV board replaced along with the power supply parts
damaged. The customer would get a bill for a hand full of
small parts. No shop in my area would touch one, it meant 2
50 mile round trips to Boston if you had a dead one.
After that they switched to a conventional hoz design &
for the most part became as easy to fix as most sets.
