Restoration Project #27 - Sony Trinitron TV

Finally, it is time to visit the first CRT TV of my channel! It is - like so many things - a random eBay find. A Sony trinitron one; Model number KV-14LM1E. Why does Sony have so weird model numbers? Oh well; besides the flat trinitron tube, it's a pretty basic model. No teletext and mono audio only. But at least it has on screen display and a remote control with only minimal battery damage. Nice.

When it arrived it was looking just like in the auction pictures, but it wouldn't turn on; I only got a "5-blink-error" code. The service manual mentions that that means an out of range value for the IKR or AKB circuit; both abbreviations seem to relate to the same error, I have no idea which is more accurate.

Anyhow, I was happily filming the troubleshooting and repair process, but somehow seem to have lost a bit of footage from that timeframe. Yikes. I hope it won't affect other projects; might have accidentally formatted the wrong memory card. These things need to get bigger so one can write on them again!

The repair and clean up as well as the adjustments are filmed again, as well as briefly explained. Geometry adjustments are done exclusively via the on screen service menu, so nothing about image size or linearity correction here. Just loads and loads of convergence controls to tune...
