Question about Computers & Internet
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,
>>>>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.
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.
