Supersonic Portable B&W Vintage TV

So in the summer I was at a car boot sale and just saw this thing sitting there. It looks so awesome and old, and just cool!  I didn’t even care if it worked or not.  For 10 euros I wasn’t going to complain either way!  So in the video we see a smoke test of the unit, just to see if it fires up and what works and what doesn’t.

It fires up, the screen appears to work but obviously there are no analogue broadcasts anymore in order to get a signal.  The tape deck played but it mangled a tape, so needs some work. And the FM/AM Radio worked lovely. Albeit one of the speakers is a bit crackly with the volume button. I’m thinking some dry solder joints there just to correct.

Back to the screen. I wanted to see if its possible to get something on there. So I hooked it up to the trusty old ZX Spectrum which outputs an analogue RF signal in a way this TV should understand.  The external antenna input is a 3.5mm audio type jack. And the output of the spectrum is a phono. So I had to jerry rig a cable together.

But sadly. I had no such luck. I was seeing wavy interference lines off the Spectrum but no picture.

Next time I am going to dismantle the unit in a hope of finding out some more information about it. Year of manufacture would be nice.  I have looked up Supersonic on the internet and found virtually nothing. I am thinking this is possibly some grey import from Asia.  Also it will be good to have a closer look at the aerial inputs to make sure they’re all connected and looking OK, as well as fix the casette deck and crackly speaker.  I think this could be restored to full glory!

If I can get a signal to the TV, then its possible to use a series of adapters on it to plug in a more modern signal, such as a HDMI source.
