Hi,
I'm opening up an old CRT TV. A VHS cassette is stuck in the built-in VHS recorder/player, and I'm going to get it out. Also I would like to repurpose the CRT part of the TV for an arcade machine in the future. My intentions are to mess as little as possible with the actual circuit and components, so I'll just build a new frame around it.
I know that one should approach a CRT circuit with caution. Capacitors inside can hold some serious charge (thousands of volts). I have unplugged the device from the mains plug. The attached picture shows a part of the CRT (in the foreground, to the right) marked "LIVE PART" on the PCB, and the shield in front of the blue capacitor is marked with a lightning. As far as I can see, this is where the AC is converted to DC.
One question:
- I suspect that the high voltage stuff to avoid is encapsulated in the grey plastic container to the left? With thick white and red wires coming up from this container, and connecting to the CRT part and the back of the screen (ground?).
I'm taking no chances here, so I'm approaching this thing slowly and carefully I'm not going to split everything apart to salvage components, etc. I just need some info with regards to where/what to pay special attention/avoid.
