Once upon a time, TV repair shops were everywhere. Now there are hardly any left. There are reasons for that, probably based on a mix of cost, reliability of electronics, and a throw-away culture. Even in the few TV repair shops that are left, would anyone actually take a scope, schematic and a soldering iron to a TV these days? Maybe they would just replace the circuit board or display.
This is a tale of a Sanyo TV, made in the UK in ~1992, based on the date codes of the components inside. It has worked continuously since then. Lately the picture has gone a bit red-ish. The TV was recently replaced by a new flat screen TV, so we’ve had a chance to take a look inside. This is the first time that the back has been off since manufacture….. ~25 years ago. Depending on your point of view, you might think that 25 years isn’t that long, but it’s not too bad either for a CRT-type TV, considering also that it has never needed a repair. If you have some other electronics that has been working without repair for a very long time, we’d be interested to hear.
Inside it is remarkably clean. Apart from the one on the tube, everything else is on a single circuit board. If the tube is not the cause of the reddish picture, then this TV is probably repairable. Some further investigation is pending. If you’d like to take a look, drop into our regular Electronics, Microcontroller and IOT evening which takes place every 2nd Monday.
Well the world has turned and another year has almost passed. What a year it has been for TOG. We started 2016 with our doors closed to the public. We had just made our big move from Chancery Lane. Blackpitts was a blank canvas for us. It was a completely open-plan space and we had to decide what to do with it. It wasn’t long before we had a proposed layout and we started building rooms. We built ourselves a fantastic common room, a classroom, a make-room to house our laser cutter and electronic stuff, and a general workshop. We decided that our traditional January birthday party and Open Social would be our grand re-opening to the public . We billed it as a monster bash, and it didn’t disappoint. It was our biggest social event ever. We invited just about everyone that we could think of, and most of them came.
Our regular Open Social evening for December, will take place on Saturday 17th December at 7PM.
