Check the electrical cord. Check the connections between the monitor and the computer and make sure the computer is on. Test the line fuse (see below). Also replace the data cord (DP, DVI, HDMI, VGA; see above). Computer Monitor Repair Interior of an older CRT computer monitor. Identify but don’t touch the power supply. If the image on the computer monitor screen is not clear and bright, check your owner’s manual for instructions on adjusting the monitor. Typically there are adjustment buttons on the monitor face below the screen. As the first thing, I’d suggest you look for a service manual for your monitor on Google. These usually include a step by step guide on how to disassemble the monitor. For example, try “monitor_model service guide” In my case, it had some weird clip thing for the back panel – no visible screws or anything – so having the manual was good because otherwise, I might’ve broken the back panel more than I did ;) Once you remove the back panel, it’ll probably look something like this. Be careful with the little wires connecting the buttons and other stuff as they can be easy to accidentally yank out. In my case, the circuit boards which had the capacitors were inside the metallic box in the center. The boards should look familiar if you’ve ever assembled your own computer instead of buying one off the shelf. Removing these two boards from the enclosure, it’s time to inspect for broken capacitors. I've marked one capacitor in red. Can you see how the top part is bulging out, like there was pressure inside it? That’s how you tell when a capacitor is broken. The other ones have flat tops, so they should be fine. It’s easier to see when you actually have it in front of you (or have a better quality Before we remove the capacitor, it’s important to take note which way the gray strip on the side of it is pointing. Each capacitor has a positive lead and a negative lead, and the gray strip tells us which one is positive. When replacing it, we must place the new one the same way as the old one was, so take note where the gray strip is. Also, if you haven’t used a soldering iron before, or are not confident enough, it might be a good idea to perhaps look up a guide on Google before going any further. On the other side of the board, locate where the capacitor’s leads. Use the soldering iron to melt the solder. When it’s liquid enough, yank the capacitor out. The numbers on the side of the capacitor tell you the type. These are used to determine suitable replacements. Now, put the capacitor (or capacitors, if you had more than one broken one) into your pocket and go to the electronics store to get them replaced. I’ll wait. Got new ones now? Now it’s simply a matter of soldering the new ones in the place of the old ones. Put the new capacitor where the old one was (be sure that the gray strip faces the same way) and use the soldering iron to melt the solder so the new one sticks in place. If it doesn’t work, you may need to apply some more solder to it. After you’ve replaced all the damaged capacitors, put everything back together and hope for the best.
