Samsung 2333HD: No Signal on Digital Inputs
I purchased a Samsung 2333HD (LS23CFUKFYB/ZA) sometime in 2010, and it worked beautifully for me.

I replaced it 2-3 months ago with a 2333SW. I had another 2333SW and the HD did not line up with the SW when mounted on a dual monitor stand. I was able to obtain a used SW much cheaper than an HD would cost me, and I wasn't really using the HDMI inputs so much anymore anyway. I packed the 2333HD in its original box, with packing sleeve and Styrofoam stabilizers.

The used 2333SW crapped the bed recently. I took it down and replaced it with the 2333HD. I cannot get a signal on either HDMI input or the DVI input. I have tried with a PS3, PS4, 360, and all of the ports on my HD 7970. I have used a variety of cables. All sources and cables have been confirmed working with other displays. All power cables have been tested as well.

When a source is connected to a HDMI input, the monitor displays "No Signal". When the source is powered off or disconnected (while leaving the cable connected to the monitor), the screen displays a "Check connection" message, and the source is not selectable.

When a source is connected to the DVI input, the monitor stays black, and then goes into sleep mode (screen is off, power light alternates on and off) after 5-10 seconds. Pressing the Menu button results in a "TEST GOOD" message.

All sources have been tested in Safe Mode to no avail.

I don't have any analog sources or cables to test the analog inputs.

I have been unable to find any Firmware to either update the monitor or restore it to factory default. The unit itself also seems to have no manual factory reset.

Does anyone have any experience with a similar issue? I'd prefer to not have to send it in for repair, since at this point, a repair will likely cost as much as a replacement. It would be a shame to toss out the monitor.
