Re: brilliance 200p3 monitor
No need to buy a replacement board just find the faulty parts in the power supply or in the high voltage section maybe there is a part shorted thats why the power cannot flow. bring this to the shop maybe you cannot spent big money for the repair instead of buying new one

Since the power led button is on, the problem with your monitor is the that the picture board of your monitor has develop fault, that is why it tries to show your desktop and quickly fades away.
The picture board of your monitor is bad and will
need to be replaced in other for it to display.
The best thing
for you to do is to take your monitor to a local repairer or any service
center within your vicinity to help with the replacement of your
picture board because the fault is not something you can fix on your own
in other not to complicate issues.
If it fades linearly, it is probably the high voltage inverter for the backlight fluorescent lamp.
Generally, the lamp dies over time with some flickering of it first.
That inverter is normally on a small, separate board and once the unit is open, it is easy to locate and replace.
scle193, What happened that you needed to replace electrolytic capacitors? Why ??? Still no sign of power??? Did you pay attention to polarity when replacing the capacitors? Did you document you work with a digital camara to make sure that you could put it back together without having any leftover parts or unconnected cables. Have you measured the dc voltages at the output of the SMPS? Have you checked any and /or all onboard mounted FUSES?? What was the original complaint you had with this monitor? Have you tried to get a service manual or schematic from Philips? Get back to me with info
if you can. lmistyrel @aol.com bye for now. louie12fix
Sounds like the back light inverter board is bad.
It's a very common problem.
LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it)
The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display.
If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad.
The inverter board and CCFL's are replaceable.
