?? Have you tried the 15Vdc supply diode? #164589 was the original part.
Also the caps in the regulated supply, near the regulator control ic, have a
way of failing causing all kinds of aggravation.

Hello Group!
Have two similar CTC169 chassis in the shop. Both showing similar
failure. One, when turned on will play perfect for up to 1/2 hour then
go into shut down and will keep trying to turn back on. If you catch it

in the "on" position you can power it down. If left unplugged for a
while, it will do the same thing all over again.
The second unit will never start up completely. Just stays on for a few
seconds - when raster starts to come up you can tell there is no
vertical deflection - then immediate shut down. The 8pin vert. IC
seems to be ok.
On both units the TEA2261 seems fine. Proper Voltages on pins 15 & 16.
Have replaced a couple caps here and there on both - but no
improvement yet. Do not have schematic for 169 here. Can anyone
point us in the right direction please?
T.I.A.
