M01KUA07WB30 – mini CRT (2)

Found this mini CRT inside a Canon UC10E camera. Even if I have already taken apart a very similar one (Canon UC15E here), I decided to buy this one too.

Overview

Camera looked clean and well maintained:

Opening Up

Camera had a two hidden catches – first was the lens ring (I tried rotating it, but I had to force it with a screwdriver to get it to unclip). And then a hidden screw under the Camera label on the top.

Camera seems to have been made after June 1991.

The Electronic View Finder unit attaches with a flat cable to the motherboard. This makes it hard to test it, thus, I had to also desolder its connector.

Few more photo with the boards inside:

View-finder

Schematics are available and it is easy to see that Pin 8 of FBT is 5V (Vcc), and pin 7 is GND (page 150 in schematics pdf).

But the board doesn’t work (although it still draws around 70mA at 5V). SMD electrolytic capacitors under the CRT measured open circuit and some yellow leakage is around them. Everything is so tightly packed, I just didn’t feel like working on it.

The schematics do not mention the CRT model nor the deflection yoke model.
