Shaun:
A CTC1187 with a stand up tuner. Never seen that before. Been doing them
since first came out, never seen a standup tuner on a CTC until the CTC203.
First time for everything, I guess. Oh well, this is what I have for
vertical problems on a CTC187. I do not know what letters are on the end of
the CTC187, so not sure on your exact chassis:
Replace Vert Chip (Tda8172) Ecg (1788) & Leaky Diode (Cr4501) Location On
Part 070*780
Solder Bad At Microprocessor Ground Shield
Cr4501 Intermittent Junction
Int Conn At Vert Yoke Plug (At Yoke) Hard Wire
Replace Cr4704 Derived Off Flyback For +12 Run Supply, Part Number 207878

This is a 1999 set with the tuner seperate from the main board. The tuner is
a stand up removable tuner.
