I understand this might be a bit off-topic for this board but I know many of you own a Panasonic WJ-AVE5 so I thought it was worth the try. Post will be removed upon request.
I bought a second-hand Panasonic WJ-AVE5 video mixer a while back. Unfortunately, the unit has issues and I was looking for some advice on how to solve them. The unit has been checked by a friend who is knowledgeable about electronics, mostly cameras and computers as they repair them for a living. They could not find what the issue was, as we did not have the schematics / technical documents of the WJ-AVE5.
By observing the video output I’m not able to tell what is happening. The pass-through circuits are working, seen in the video below. It appears to be some sort of sync and chroma issue. I have tested both the Component inputs - outputs and S-Video inputs-outputs.
I have tried both camera, visual cortex and video game console inputs into the WJ-AVE5, both with composite video, and S-Video when possible. The same issue is present in both channel A and B. The internal wipe effects is working properly, as tested with one of the channels’ video set to back colour mode.
The main signal flow is as follows:
NES Composite Out → WJ-AVE5 Source1 Component In
WJ-AVE5 Preview Component Out → CRT TV Component Input A
To verify if the pass-through is working this is done:
WJ-AVE5 Source1 Component Out → CRT TV Component Input B
Here I show the system used and toggle between the TV inputs:
This one focus on the video issue on the screen:
A photo of the input and ouputs in the WJ-AVE5:
In the video below I input Visual Cortex’s Composite Output into Channel 1 of the Panasonic WJ-AVE5. Cortex’s [Chan. A Mix] switch is on and the video is initially white. I then proceed to zero each color channel and putting it back to max in turn. Red, Green, then Blue.
Note: Strobing is caused by digital camera recording.
Any feedback is appreciated. I’d very much like to be able to repair this unit. Where I live there is little secondhand market and it is very overpriced due to scarcity. If someone has manuals for the unit, to help a local technician that would be of help also.
Thank you all for your time!
