Thank you all for all of your help. Especially helping me to figure out which model of device I have (PRIME)

First a mistake on my part. There are indeed only three LEDs on the left side (not four)

Then it gets a little strange. Until this evening, all three of the left side LEDs were solid green ...

Looking at the front of the device,

Four lights on the left side are green, then, the two on the right side, left LED is solid green, then last LED on the right side is solid red

I have the 3 tuner HDHomeRun. I've been very pleased with it for many years. Just recently (past couple of months), it won't be recognized by my W11 Pro computer. I have the 4 green LEDs on the left side. I have two LEDs on the right side. They are green and red (solid, not blinking).
