IC Power 19'' LCD-Will not Power Up- No Lites.
This is a follow up to my last submission about my discovery of bad caps on the FPD1960 LCD flat screen Gateway 19" computer monitor. To recap: After two and a half years of excellent graphics quality, my monitor suddenly went blackout. After pushing the power-on button, the screen would come on for 1-second, then go black. Repeat, again and again, same result; comes on for 1 second then blackout. THE REPAIR: After carefully but forcefully prying open the case, I unscrewed and unplugged then removed the screen and set it aside, then unscrewed and removed the power supply board. Sure as shootin, bulging (and slightly leaking) capacitors were immdiately apparant on this board. That other fella's submission was right on target. Search Wikipedia for "bulging capacitors" to get the inside scoop on this widespread problem. Major manufacturers are well aware of this issue, but fortunately for them it occurs some 2-years out'a the box, and after the warranty expires. This is one time I wish I'd bought the extended warranty! Anyway, I finally got my 5 caps from Ebay in the mail today. Specifically, they are 470uF 25volt 105-degree (use only 105's because some are right near a power transister heat sink---so I'll bet they get mighty friggin hot. After carefully replacing the old caps with the new (you'll need a solder ****** along with your solder iron), I reassembled, powered-up, and began to thoroughly enjoy the fruits of my labor. It's working like new once again. THE CAPS ON THE POWER SUPPLY BOARD ARE DEFECTIVE.
