20 Most Recent Proview PL926WBi 19" LCD Monitor Questions & Answers

Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums

I know it's an older post, but you still may be waiting an answer:
What is probably happening is Your power board is failing to maintain power enough to run the bulbs and the rest.
That is why it takes long to start up and why it goes into sleep mode.
Does the power button stay lit (getting signal) or turn to amber (sleep mode) or does it flash.

Does it have the square button to the top right to enlarge the picture to normal view?

Try disconnecting the monitor from your computer and checking the pins in the connector to see if any of them are bent or flat. If they are, try to straighten them if possible and that may resolve your problem. Otherwise try resetting your monitor, if it has it as an option in it's configuration menu to do so.

unsoldering is the only way to UN-mount capacitors the board needs to be out of the casing. a solder iron and some electronic solder wire can be bought at radio shack or any other electronics store.
procedures are all over the internet

Bad capacitors on the pcb boards internally unsoldering ad replacement is indicated.

Public sales or auctions from corporations or schools are the best places to get computer cables for very very cheap.

If you are looking to purchase new cables places like

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.

bad capacitors on the board, replace these and the inverters should get there power.

Remove all the screws and stand first, then use thin flat blade screw driver to crack it open at the bottom edge of the case and then work your way around and becareful on the ribbon cable attached to the front panel.

Hi.
Sounds like the power-inverter board is due for an overhaul.
Eventually it won't turn on at all.
I do redo many of these.

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.

Capacitors are bad. I fixed one. There was 470 uf that was blown.

Go to electronics store and buy 6x470UF 25v. Thats how i fixed mine

Remove the four bezel screws on the bottom edge of the monitor. Gently pry up where you removed the screws and slide the bezel off towards the top of the monitor. The six mounting screws for the lcd panel will be visible. Remove them and inplug the lcd cables and set it aside. You now have access to the main circuits.

You can not degauss a LCD monitor.

Degaussing is to reallign the magnetic field on a CRT. An lcd has no such field.

The last time I heard of someone wanting a Degauss for an LCD, it was because there kid took a magnet to there LCD monitor. This will destroy the TFT pixels.

have a look at the board open up the monitor and remove the boards and you have to look for doomed or colored caps, they will be obvious compared to the good flat caps on the board. replacing these will most likely repair your issues.

i have the same monitor and it flashes on and off! i am willing to sell if you want to buy it
