Capacitors??? WOMAN NEEDS HELP PLEASE!!!???

I have a Proview monitor Product # PL913s Model 900P. It has no power. When I opened it up, there are burn marks near two of the capacitors. One was, I believe, 47ouf 25v and the other is 25v 150ouf. I am looking thru the catalog like you suggested for a 105c but what capacitor should I get? The same as it had or something stronger? What parts numbers do you suggest? Cause I certainly wouldnt want to get the wrong thing and blow it up or something serioulsy happen to it.
Your help is greatly appreciated.

Thanks for your help in advance,
Annette

>>>>You do NOT need a driver. Your monitor is broken. The high voltage power supply that provides power to light the CCFL cold cathode fluorescent lights is broken. The most common problem is that the 470uF 25V capacitors on the power supply circuit board are bad. Bad Caps have a swollen and sometimes leaky top. There are 6 capacitors that cost about 50 cents apiece from www.partsexpress.com . Buy high temperature replacement capacitors rated at 105C. If you can't de-solder and resolder have some 14 year old kid do it for you.

    I have the same Proview Pl913s 900w 19" monitor and the screen was white when I came home from work, from there I turned it off for about a hour to two and tryed to turn it on again and it powered on and then off, So I read the posts on here and changed 5 of the 6 caps and now it powers up but screen is white, tried to let it warm up but it shut off after 10 mins any suggestions

The term: "it has no power" is not specific enough. If the actual led indicator light on the front of the monitor lights up with a green color, then goes out or starts flashing, then maybe, perhaps the problem with the monitor is that the high voltage power supply for the screen backlights is not working. The common components that fail are the capacitors on the high voltage power supply board. If the capacitors are swollen or leaking, they are probably bad. You must replace a capacitor with the exact size of capacitance. You cannot replace with a "stronger" capacitor. You can replace with a higher temperature rated capacitor, if the capacitor will fit in the alloted space on the circuit board and in the case.

Hello, i need the inverter for this monitor proview pl913s silver 19 inc. flat panel lcd. product# pl913s The monitor turns on and shots off after a second. how can i resolve this thanks


Did you inspect the caps for domed tops in the power supply/inverter board yet? Worst case will be the lamps assembly.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed 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 to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

I have Monitor Proview PL916S 900P It turns on


spc12b, Have you tried the flashlight test yet? How old is this monitor? Your monitor has a 2 types of power supplys in it. A switch-mode-power-supply and an "INVERTER" supply. One or both of them could be having a problem. The inverter needs DC from the smps to change it into AC to light up the cold-cathode-fluorescent-tubes that are hung in back of the lcd panel. Let me know results of flashlight test. After screen goes black, hold light 1-2" from screen at different angles. Let me know if you still can see the win-desktop screen even though it is still dark.. Bye for now. louie12fix on fixya or lmistyrel @aol.com

Monitor works on one computer, but not the other


The problem is not your monitor, but the video card on your computer that it doesn't work on. If the video output on your computer is built in, residing near your keyboard / mouse ports, you can purchase another video card to put into your computer and connect your monitor up to that instead. If it attaches to a separate card inside your computer, just replace it. There are three kinds you can get, AGP, PCI, or PCIe. Make sure you get one that will fit inside your computer.
