Question about Proview PL926WBi 19" LCD Monitor

2 Answers

Only brief display on my Proview PL926Wbi monitor

When I turn on my monitor, it will display the computer screen quite beautifully for only a few seconds and then goes black. If I turn it off for e few seconds and then back on, it will do the same thing but only for a few seconds. The power indicator remains blue the whole time, even when the monitor is black. Can this be repaired? If so, how? Or should I just trash it?

Hi
It can be repaired in most cases.
Your's sounds optomistic.
What needs to be done is your power-inverter board needs to be overhauled.
I do these on ebay.
If your picture wasn't pinkish or dark at the top or bottom when it was working, then it sounds like probably the inverter was going and finally went. They are light light bulbs and have life expectancies on the capacitors.
If your picture was pinkish or dark at the top or bottom when it was working then you may have 1 or more of the bulbs failing.
To get to the inverter:
Once the four screws are out of the bottom edge, the the trim slides upwards to unsnap it.

You will probably have to lift the top edge away from the screen itself as you are sliding the trim up because it will hang up on the screens metal trim that is underneath.
Then unplug the screen video cable
At this point to verify possible bulb problems you can plug it in a turn it on.
bad bulbs will usually show their face here.
IF bulbs look okay then unplug the backlight bulb plugs.

The the inverter/ powerboard is under the center area under the metal cover which is screwed into place.
Shout if you need more info.
If you email me a good picture of the inverter in the area of the larger yellow square component, I may be able to get a better idea if it is the inverter from a visual.

Thanks

Does my Proview PL926WBi 19


Any monitor will work with any computer provided the correct graphics card driver is installed. When you install Vista and you do not install the graphics driver, Windows will default to Generic VGA driver and you will not get the best resolution that the monitor can display.

I NEED HELP PLEASE!!!!!!! PROVIEW 19" MONITER.


Does the led on front of the monitor stay blue or does it become amber ?
If it becomes amber, then you are not getting a signal.
No harm in trying this : You can try to see if it is a contact problem.
With the monitor unplugged.
Use a small paper clip to run in and out of the blue vga plug holes a few times each to make sure they are not plugged or gummed up.
If that doesn't help and you know that your video cord is good, then I am afraid to say that more than likely there is a problem with yor video card.

If it stays blue then the signal is there but the screen isn't fully lighting up, leading to a failing power-inverter board or a bad bulb.

Blank screen with message "mode not supported"


Hi

How have you connected the monitor to the computer?
Is it through the vga or the dvi port?
Pls press the monitor menu button and change the mode to vga or dvi depending on the connection that you have now.
You might also get a vga to dvi adapter and connect the monitor to the computer.
