Re: Jvc gy-hd*** camera family re-attaching blue sensor.

If one goes west, it is usually into the ocean so I guess the connotation of "going west" means lost or broken as if it went into the ocean or went missing over the ocean. In Texas I believe you have...

Re: Jvc gy-hd*** camera family re-attaching blue sensor.

John Nantz. I don't know that camera model. My sense is that the chipset in the camera itself has been programmed to work only with that particular LCD screen as built in to the camera.

Re: Jvc gy-hd*** camera family re-attaching blue sensor.

Here is a small piece of motion vision of the detached blue sensor being slipped into near-alignment. You'll need to be quick to spot it.

Re: Jvc gy-hd*** camera family re-attaching blue sensor.

Re: Jvc gy-hd*** camera family re-attaching blue sensor.

A small update.

Here is an illustration of a temporary support for the detached sensor which enabled me to establish just where in space it should be.

Re: Jvc gy-hd*** camera family re-attaching blue sensor.

For those who have the endurance to remain curious, any bridge pieces which are made have to be vented to allow the small fan to push air through. The little processors on the PCBs the sensor chips...

For what it is worth, here is a rather shoddy phone pic of the LCD screen of the image yield with the blue sensor relocated. I used roughcut bridges made from cereal packet cardboard with a razor...

Re: Jvc gy-hd*** camera family re-attaching blue sensor.

For the curious among readers, from appearances, it sees that the sensors are attached by temporary mounting strips and wedge ends to an assembly jig. There are eight holes altogether some threaded,...

There was a little white indicator arrow popped up on the LCD screen which I had not ever seen previously and suggested which direction the sensor was not in vertical alignment. One time...
