At this site you will find resources and schematics for repairing your own Audio Gear. The video above is about replacing bad caps in your lcd monitor. The monitor presented is a Samsung SyncMaster 204b which is a great monitor except for the cheap chinese capacitors. The difference between mainstream LCD monitors is quite small in regarde to changing these caps, so what ever LCD-monitor you have, you will be able to locate these bad caps, read the numbers and letters on them, buy new ones and replace them. The only critical things are:
1. Turn the power off!
2. The capacitors are polarized (like a battery) so it DOES MATTER how you place it. Look for the minus sign on the side of the capacitor and take a note (or a photo) so you know which leg goes into which hole! The minus sign is the ‘minus’ leg.
