V-4EX Repair Help

1

I’m looking for anyone with knowledge of repairing a V-4EX, feel free to message me directly if that’s you.

Any help gratefully received.

Everything works except for composite input/output. Guess what I really want? Composite i/o.

Details:
Updated to 1.530, factory reset, video inputs set to composite, hdcp off, set to ntsc for ntsc sources.

Inputs only register seeing a composite connection when plugged in to the Hypno, not other video sources. But even the Hypno signal comes through on screen as black & white noise.

With other inputs (structure, mainbow) they don’t even register that a composite connection is present.

The composite output doesn’t send any signal.

I am adding photos of the internals for posterity and the curious:

Well I see your problem, the circuit boards are supposed to be inside the case! :stuck_out_tongue:

In your video input settings make sure you change your inputs from HDMI to composite.

Thanks for the reply.

I put the circuit boards back where they belong.

I had changed the video input settings to composite.

I have a feeling that the chips or components which process the analog signals are duds, as some desynced visual noise comes through while VGA & hdmi work.
