Obviously almost all of my family's devices recogniced me being out of business due to COVID19 and decided becoming defective in the last time:screwy:
I already repaired my car, dishwasher, tape recorder, bedroom radio and the most important thing: the electronics modules of my gas heater :thmbsp:
Last week my dear mum gave me a call because the power switch of her 1995 CRT TV stopped working mechanically.
Yesterday I took the set apart and replaced the switch I randomly had in my toolbox. Knowing that this TV was intense used during the last 25 years I wanted to know more about the condition of the CRT. As you can see red has approximately 1mA, green and blue 1,2mA emission.
Due to this unexpected good values I further replaced a few dried out electrolytics and adjusted voltages and geometry.
The picture quality is still great and we set an example against throw away society :yes:
All in all this set had 3 defects in the last 25 years. I was able to fix all of them with resoldering and non expensive components like resistors and electrolytics. CRT, LOP and LOT are still original from 1995.

Transformer and transistor were meant.
