14cm B/W CRT RF only composite hack? Can't Post

After pondering for a quite a while and no luck with a google search, I thought I'd join your forum. So Hello to all of you.

I have a 14cm B/W CRT Model number is W5503. I'm not sure of the model, it says ETS Germany on the back but don't this this is a brand.

The TV has only an RF socket so I was wondering if a composite video signal could be picked up from somewhere on the sets main PCB?

Is this something anyone cold help with? If so I can take some photos of the PCB.

Some details and images of the set can be seen here:https://www.radiomuseum.org/r/unknown_personal_black_white_tv_amfm_radio_w5503.html


Thanks In advance

You may find places listed on the PCB for Video/Audio In/Outs.
Otherwise IC Type numbers Used for Jungle IC, etc.

Thanks, the IC is a CD5151CP I did some googling and found the composite to be on Pin 5 is it really as simple as connecting my composite signal to this and connecting the ground at a suitable point on the board?


Or am I missing something obvious?


Will this siganl override the RF signal or will it have to be activated elsewhere?

Thanks

Just leave RF connector empty.
