I found another Miyota 2400-58 picture tube inside (this time) a JVC GR-AX210EG camera. Since I have already found it in other JVC cameras, and given that this specific camera was working – I decided to not test it.
The camera came in a carry bag and was impeccable aesthetically. Except battery having leaked (and me having to scratch the terminals to be able to apply power), the preview / playback worked fine.
Battery leaked and was swollen but camera was sold with the power adapter, which made testing it a little easier:
Since I had the power adapter and there was already a tape inside, I decided to give it a try to see if the CRT works, and it did! There was also a tape inside with word ‘LEEG’ written on it. Google translates it to ‘Empty’, but the tape has footage of some renovations ongoing in a flat.
I have proceeded with dismantling the camera, which (according to the date code inside) was produced in Apr. 1997:
It was however refreshing to see there were no bodges on the board of the camera:
Finally, I took apart the EVF unit – where I found the Miyota 2400-58 and the BA7149F driver IC.
I have not proceeded with the tests, but I did try to identify the VCC and GND signals going to the EVF Unit. If I call PIN 1 the bottom pin of the connector below, there is a direct connection from the metallic case of the Fly Back Transformer back to PIN 5. There are also few pins (which I assume VCC) on the FBT that have continuity to PIN 9, which should then be VCC:
I have more JVC cameras to take apart, thus more Miyota CRTs to be salvaged 🙂
