replacing capacitors

You may have booted up your laptop one morning and found that the LCD screen suddenly seemed to be having problems. If you don't know much about LCD monitor repair, you may wonder what you could do about it. Many people go to a repair technician, and end up having to spend a lot of money, but this is usually only because they're ignorant of how easily repairable most laptop issues really are.

The simple fact is that some problems with a laptop's LCD are easily solvable, and these issues are also the most common ones. Of course, if you've dropped your laptop on the floor and your LCD is in four pieces, you shouldn't expect to be able to repair it, but if the issue is something more simple, like a flickering screen, you certainly can expect to be able to do a little LCD monitor repair yourself.

Now, the usual issue when your screen flickers or develops lines in it, lies in the capacitors that power the inverter board of your LCD, or in the capacitors that help power the video card. The bottom line here is 'capacitor trouble', period. Now, there's nothing to worry about. If you're a handy man (or woman) with a soldering iron, you'll get those capacitors replaced and your laptop screen working again in next to no time at all.

Generally speaking, you know that there's a problem with the capacitors if you have issues with the screen, but it still seems to be working, no matter how badly. Open up your laptop and lay open the video and inverter circuit boards, and examine them carefully. If you're not certain which boards these are, look up the manufacturer's manual, which is usually easy (and free) to download off their site.

That's all that it takes. Now, when you have the inverter and the video boards before you, examine the capacitors on these carefully. The top of each capacitor should be flat. Should you see one that seems to bulge upwards slightly at the top, you know that this is one that is 'blown' and that your issues with your screen lie here. From this point, repair is easy. You just need to acquire the exact capacitor and to replace the damaged one with the new one, and voila, the screen is working again. I'm not kidding. LCD monitor repair where the issue is damaged capacitors is really this easy!
