HP W1907 Monitor goes black after resolution change

This sounds like a power board problem. Could be failing power capacitors, which are allowing the charge to leak ( stripping the screen, not recommended) will show bulging or leaking capacitors). Or it could be an issue with the PCB. The fact it will restart once it has "cooled down" points to this.

I'm assuming you have tried the monitor on a different computer, just to eliminate the graphics card (unlikely but worth a go)

Solution..get it checked by a qualified TV repairman, it may a be a simple fix.

If this monitor (HP w1907) is going into sleep mode the normally blue power led will change to yellow. This indicates loss of video signal or possible out of range resolution. If the picture goes dark and the power lite stays blue, you have a backlight malfunction. It can be an inverter power fault but this model mostly has worn out backlights causing a shutdown condition.

Hello,

The picture board on your monitor is faulty or bad, since it goes black after few minutes, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board or any service center because the fault is not something you can fix yourself. in order not to complicate issues.

Take care.

Hi

Please try this monitor in another PC

If it fails then the monitor is faulty as it seems to be heating up and then cutting out


Please can i ask that you leave feedback and vote if this has been useful

First place to check will be the power supply section, look for bad caps with bulging top or bottom seal, post back what you see so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

You could have a faulty inverter board. The inverter supplies high voltage to the CCFL lamp/s, these lamps are mini fluro tubes approx 1,5mm dia. and the length of the screen.
Check the inverter output/inverter board and you maybe able to get parts from
www.lcdparts.net

it sounds as if you may have a backlight problem..i have two of them that the wire going to the backlight had burnt off at the bulb..I had to take the lcd screen apart to solder the wire back on the blub.. be carefull the lcd screen and bulb are frigile... ther is 4 lights two on the top and two on the bottom..good luck

You need to increase the resolution of your desktop.

Goto Display Properties->Settings

Right click on your desktop, go to properties, and navigate to the settings tab. There, try to set the monitors resolution to the largest available. That should fix your problem. If it doesn't just try some other resolutions until ou find one that works. I hope this helps, Yannick.

This is normal. BUT it should only do this while launching, once it hits the main menu clearly. It should be fine.

2. If you alt tab while the process is running, you may see the resolution change. But if you close it properly than it should not change except for those reasons/times.

Contact me if none of those do work,
