3859Studio II schematics?
- Jun 18, 2005I forget if I've already asked here or not, but does anyone have
schematics for the RCA Studio II? I have one here that responds in a
reasonable fashion to button pushing in terms of beeps and noises, but
with absolutely no picture. Scoping the video area seems to indicate
that the TA-whatever Pixie chip is emitting reasonable signal for
video, but nothing seems to be coming out on the TV screen.
To ensure maximum signal compatibility, I am using an old B&W TV,
tuned to the right channel, etc.
So... if I suspect the problem is in the (onboard) RF modulator, does
anyone have a schematic so I can trace out where the signal stops
being passed along? There's a CA3086 5-NPN DIP in there that I'm
currently somewhat suspicious of, if for no other reason, the other
components in there look somewhat robust (1/4 W resistors and ceramic
disc capacitors and a few coils).
Thanks for any pointers to info,
