E228WFP, screen goes into Auto-detect blacks out

Question

I have an old E228WFP with a Dell Inspiron Desktop. It has worked perfectly fine .... until today. Suddenly, during a video session (not Zoom), it went black, even though power light was on. I turned power button off and on several times, but it kept popping up with 1-auto-detect (analog) and blacks out again.

I tried a different Monitor, which works fine. Thinking maybe my reset of the sleep mode for the monitor last week or so (extending length of time), I went into the settings and set it to "Never." then I reconnected the Dell and same thing happening. I have unplugged blue plug from computer, but kept power on, and don't get the "floating test screen" shown in knowledge base.

Is the monitor entirely kaput? Is there a way to fix this?

For this out of warranty monitor, try this =

Monitor power cable/ button reset
* Turn the PC off
* Turn the external monitor off
* Disconnect every cable (including the power cable) from the external monitor
* Press the external monitor power button in for 8 seconds (clears any residual power in the circuits). If not a mechanical power button, just wait 8 seconds
* Reconnect the power cable and one video cable to the external monitor and PC
* Turn the external monitor on, then the PC

Thank you. (The monitor is disconnected from the computer as I had to connect a different monitor in order to type here!) I tried what you suggested, but when I reconnect the power and turn on the external power button, it just flashes "DELL," then the auto-self test box with red/green/blue/white pops up, then screen goes black again. Is there something on the text box which will tell me anything?

I don't know if it means anything, but yesterday when I was trying to get screen to stay on while it was connected to computer, I hit the Input Source Select Button, it went from "1 auto-detect (analog)" to "2 analog;" when I disconnected the power cord and reconnected it, it went back to "1 auto-detect (analog)." There is only one blue analog cord on this model.

Do you think there's any way to fix this or is it "toast?"
