My 1997 vintage KV32S22 died completely during the final moments of the AFC
playoff game last month. After reading this group and a bunch of googles, I
decided to give repair a chance. A few minutes with a meter showed the
common failure mode of a shorted HOT (Q502) that killed the PS choppers
(Q601 &Q602) and the fusible resistor (R607). I replaced the failed
transistors with quality OEMs and R607 with a Sony OEM. I removed, cleaned,
and resoldered the HDT. The set now powers up, responds to the remote
(on/off, channel up/down, volume, mute, etc.), and provides sound but no
picture. The standby blinks at a constant rate which I understand means a
bus problem or IK issue. Since the remote functions, I'm assuming the issue
is IK.

I don't have an Oscope but I'd like to continue down a repair path. If the
IK issue is due to a bad tube (common on the 32" sets like mine) I guess it
means a new TV. Any easy way to test this? If not, what do I check next?
Any "most likely" part replacement for this condition?
