SONY STR-DN2030 7.1ch AV Receiver - Serial Number 2? Junk

This is Sony's AV receiver, the STR-DN2030.
It supports 4K pass-through and upscaling.

I acquired it about 5 years ago and used it until 2 years ago.
There were no particular issues until the last time I used it, but upon performing a light operational check for this listing, I discovered a malfunction, so it is being sold as junk.

The reason for it being junk is that the relay clicks on and off when the casing is touched or pressed. It is likely due to poor contact, a solder crack, or something similar.

Also, since I acquired it, the FL display on the front panel has been very dim. It is almost invisible in a brightly lit room.

Operational checks were limited to video output and remote control operation.

The serial number is 2200002, but looking at other units, they all seem to start with 22? so it is likely a very early model. However, this is unconfirmed, so please judge for yourself.

As it is an older item, there are scratches and dirt on the unit overall. It looks dusty and dirty in the photos, but I will clean it before shipping.

Included are the amplifier unit, remote control, instruction manual, radio antenna, and sound field measurement microphone. It does not come with the original box, so it will be shipped wrapped in recycled cardboard.
