Lenovo Desktop problem

A couple of weeks ago when I turned it on the screen would blink (at start up) and go blank.

The original computer monitor stopped working but would work hooked up with HDMI out ( toTV set or another monitor).

I just turned the computer off manually because it froze up and turned it back on and now it works again.

One thing that happened the last time it worked properly was the computer screen was darker on the bottom right hand corner while previously it was darker on the upper right hand corner.

Computer is 4 or 5 yrs old and don't know the model number.

Re: Lenovo Desktop problem

How is the computer connected to the monitor? HDMI or DisplayPort? Have you tried a new cable?

Re: Lenovo Desktop problem

Is this an all-in-one where the PC is built into the monitor?

It'll really help if you can find the model number. On this warranty lookup page, there's a "detect my device" option that should be able to pull up that info for you:

The PC is built into the monitor.

Can't read the model number on the back of the computer because the print is too small .

Could the off/on button on the side of the computer have a short in it?

I was going to call a repair guy in the morning but my central air just went out and that's a priority one.

If the PC actually still turns on/off, even if the monitor doesn't, it's not the power button. Based on the dimming before it stopped working completely, it's possible the backlight is out on the monitor. You can try looking close to see if you can detect an image at all, if it's in mirror mode with the external monitor try moving the mouse and/or windows around to see the change.

As an aside, this is why I hate all-in-ones, since if the PC goes, you also lose the monitor, and if the monitor goes you're stuck with a busted monitor if you want to keep using the PC. At least yours has a way to plug in an external monitor.

Did you try the website I linked to in the previous post?

Re: Lenovo Desktop problem

I will try that website in a minute because I was using another computer.
I just restarted my PC and the screen is working again. That doesn't mean it will work the next time.

Update:
Went to the website:

Re: Lenovo Desktop problem

I talked to the computer repair person and he said it's a bad monitor and can't be repaired but I can still use it as long as it's working with the external monitor.

I still need to figure out how to send audio from the original monitor to my stereo system while still using HDMI cable to the external monitor.

I assume you're using the "headphone" output on the PC? What version of Windows are you on? This link shows how to change the audio output in Windows 10:

9 times out of 10, the one you want is labeled "Speaker" and "Realtek High Definition Audio".
