No picture or sound on DVD recorder, HDMI port not working?

[dr.technical]

I recently started getting a black screen with no audio when trying to use my (hard disc drive) DVD recorder. Changing the cable did not help. A representative from Magnavox thinks the HDMI port on my recorder is the problem. My DVD recorder is about 10 years old, Magnavox MDR533H/F7.

I was thinking of trying a RCA to HDMI converter. Does that sound like it might be the solution? The ABLEWE RCA to HDMI converter has gotten some good reviews.

Have you tried using RCA(composite) strait to whatever device that plays the audio ?
Meaning amp or TV.
If you have audio that way it must be in the HDMI.
Before trying an adapter try a new top quality HDMI cable.
Do you have another TV etc with HDMI you can test your DVR with ?
To make sure that the problem is your DVR?

I have 4 HW2160MW9 DVRs & I have never had a HDMI problem.
A bit older than your DVR.Visually they look the same.

I think I need a adapter for an RCA cable. My TV does not have RCA ports. I only see HDMI ports and a USB port.

I tried using the HDMI cable that I use for Roku on my DVD recorder. It did not work.

My PC monitor just has a VGI port. I don't have another TV.
