ASUS PA238Q no signal

[darcy505]

So I use an Asus PA238Q as a 2nd monitor, and yesterday as I started up my PC, it flickered briefly after I entered W10 password and it never turned on... just went straight back into standby mode.

It usually detects the input and swaps to it automatically as I understand it... so as the PC was on:

- Tried changing the DP cable for an HDMI one... no bueno.
- Tried plugging in a blu-ray player via HDMI too, no bueno.
- While in standby mode (via DP cable), the standby light indicates white so it thinks there is a signal, but the actual panel is off (deep black)

Windows it detecting it as a second monitor, its assigned in the W10 'Display Settings' menu, but no picture!

Never had a monitor problem like this, does anyone have any ideas I can try before I resort to taking it to an electronics repair expert for diagnosis?

Can you list your specs like so:

Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Can you see if uninstalling and reinstalling your GPU drivers alleviates the issue? Are you on the latest BIOS update for your motherboard?

Can you test the monitor with another computer or any kind of device that can output something to its HDMI input? Just to rule out that the monitor dies. It happens, btw.

Unplug the power cord to the monitor and plug it back in.

Thanks for your suggestions

- I just tried turning off and unplugging for a few mins - then replug and start - no bueno
- Tried connecting the monitor to the HDMI of a standalone blu-ray player - no bueno
- Tried a clean install of latest nvidia drivers - no bueno (no nvidia driver update prior to breakdown, so I'm thinking its not this)
- Running the latest motherboard BIOS (no updates near the time of breakdown)

Additionally, I press the change input button but I can't even get the menu system up on the monitor, so do you think its a broken panel?

Can you get into the bios?

Can you get into the bios?

Monitor bios? I don't know how to do that.
I can't get the panel to even turn on with any button presses on the monitor itself

 

[SgtScream]

No, I mean is the bios splash screen visible with the affected monitor so you can get into it?

yes I can get in to the motherboard bios as I am using the failed monitor as a secondary screen

I see no splash screens at all on the monitor, the panel is black as if its not "on", the the standby LED is white as if its receiving a signal

If you cannot get into the bios with the affected monitor, booting your computer into safe mode results in no display and a second monitor works fine it is safe to say there are no problems with your computer hardware. Your monitor is defective and hopefully still under warranty.

Oh I know there's nothing wrong with the computer - I know that much. I was hoping there might be an asus monitor tech guru lurking and ready to drop an amazing hint or button combo that I can try before throwing it away.

its not all bad though, as the height / pivot / swivel stand it comes with is still better than most stands today, so I've detached it and ready to use it on another monitor

The monitor? Early 2012, so its out of warranty, and its outside of the UK 6 year electronics consumer protection law
I guess I've used it pretty intensively, but I would have expected it to last a little longer

Dead monitor, everything points to this fact.
