Re: Help wanted with B/W TV Mod
Update to this Project.
I have managed to feed the Composite Video in at the Base of Q801
and have set up a 3v operating point which gives me a basic Picture of sorts which
is an excellent start.
However, the Vertical Hold is quite weak and the Horizontal looks quite
distorted. So I am assuming I don't have the necessary Sync.
On looking at the Schematic, it looks like the Video and Sync are already normally
separate at this point, Sync on K5 connector and Video (where my new Signal is injected) on K4 going to Q801's Base.
If this is the case, can anybody suggest how I go about inputting the required Sync, if indeed that is the problem?
Also,
I have ordered an old PS1 modulator to try out the other suggestion in parallel.
