World's Smallest SONY Trinitron TV - Multiple FAULTS - Can I FIX it

This Beautiful Sony Trinitron Portable CRT TV from 1980 Model KV-4P1 was sent in to me from Elliot ‪@TheRetroFuture‬ as he could only get a green picture on it rather than colour picture. I also found out it had multiple other faults like no sound and buttons not working. It should be fun to see the inside of this as it was cutting edge in 1980 and very expensive, can we get it going again? Let's find out! Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in these videos. Many thanks, Vince.
