I took another trip to Newark antiques fair last Friday, came back with a few bits again! One being this little Fergy pocket tv, a PTV02, not sure when it dates from, but a guess would be from the late 80’s to early 90’s. It’s got the same innards as the Seiko LVD-204 from 1989.

I stuck some batteries in it and it lit up, which seemed promising, but trying to find a signal got nowhere, just had the green tuning line going back and forth. Connecting a composite signal to the AV socket produced a decent picture, so there was some hope for it!

I had no luck finding a service manual, so had to just guess at what does what. Taking the main board out to inspect it revealed nothing that looked bad, all the capacitors are through hole electrolytics, or surface mount chip types. None look to have leaked. One thing that did stand out was a 75R resistor tacked between ground and one leg of the AV socket, at a guess it was connected to the video terminal of the socket, it certainly didn’t look like the manufacturer put it there, unless they were really bad at soldering!

I decided after much prodding about to try lifting one end of it, which cured the problem completely! This time when turning the set on there was actually snow on screen whilst it was tuning, before it was just dark.

So that can go into the collection of tiny telly’s! I also got a boxed Casio TV 600D.

I'd say someone has done that to lock it into AV In mode.

Quick fix reminds me of an early 70's 24" all SS Pye T26 a fellow collector dropped by with a few years back.

This TV had never had the back removed since it left the factory at Marrickville, evidenced by an unbroken seal on one of the screws.

No picture, except for barely-visible highlights at max contrast.

CRT G2 measured a measly 100 volts.

820k dropper resistor measured tens of megohms.

Replaced it, put up a test pattern, pic was bright, sharp and perfectly aligned.

Screwed the back on, nothing else to do!

50 years and just 1 resistor! Must be a new record!

It’s amazing how some sets get away with so little attention over the years! The ones that never seem to go wrong are the little 12” black and white portables of the late 70’s and early 80’s, I have a few of those still working, most were thrown away at the tip, which is where I got them! Our old Toshiba from 1987 still works, all that’s had the back off for is some dry joints in the mid 90’s, and then I took out the switch bank to clean the contacts as it was getting very hard to select a channel. The tube looks a little ropey these days, but it still works!!

It's amazing how much those early Toshiba in-lines can be improved by just re-doing the setup on them.

Although, '87? That would have the self-converging CRT.
