Rca ColorTrak Spacesaver turns on and off repeatedly

IIRC TP15 is front & center on the PCB. Look at the bottom of the
chassis for a darkened spot from the xistor overheating. Its
a small xistor.
The part # listed for TP15 may be the old or new number. IIRC there
is still an old RCA parts distributor with NOS parts. They should have
a bin full of them. Sry I dont remember there name.

good luck es 73 Zeno

I’m not seeing a TP15, nor am i seeing any burnt spots on the board. I’m also not seeing any cracks on the board either.

These sets had a screwy way of labeling parts. Ex. TP15 means
" Transistor Power supply #15" Every stage has a designation.
Most sets used numbers like Q801. The 800 series numbers were power supply.
IIRC TP15 was the on/off for the set. Hows about a pix of the chassis ?
Also if you have a schematic post that.
