In the old days when I was a kid (60's) phone our TV repairman. He'd turn up with a couple of old battered suitcases full of valves and take the moulded board off the back of the set. One or two valves replaced and a couple 'twiddled'...fixed, it used to fascinate me. Now the car stops, don't even bother opening the bonnet just call the recovery service. And I used to keep spare points, condenser, coil and a bit of wire in the boot, guaranteed to get you going again!Like fathers Grundig Colour TV that got expensive to repair. The dealer replaced large circuit boards and it got rather pricy (£300 at a time, 30+ years ago). Old days you'd swap the valves or solder another capacitor on when they went leaky. Repeat... repeat. He passed and mother started off on it again. I said just get rid of it and buy a new TV. The curse of the integrated TV circuit boards. Now we dont repair, just out it. Something to be said for TV screens now just being monitors rather than cathode ray based. Just need modern day TV reliability in cars....
