[Andrew] sent us this great breakdown of an LCD monitor repair. After his wife’s monitor developed an issue with rippling in the picture, he was forced to decide between trashing it, or fixing it. He decided for the latter, possibly to his wife’s disappointment. The rippling image could easily be attributed to a failed filter in the power supply. Knowing that capacitors are a prime suspect in these cases, he tore in, looking for failures. He found that there were, in fact, 2 bad capacitors on the back light circuit. After replacing them with newer, higher quality ones, the monitor was as good as new.

LCD Projector Repair

[Kieth] picked up an Infocus projector only to find that it needed some repair. The polarizer on the blue light path was toast. When he parted out an Optoma projector he scored a polarizer that was just about right for the repair. It’s a good read even if you don’t have a projector in pieces at the moment. He ended up bending the mounting bracket a bit to hold the filter and got his projector fully up and running again.

What To Do With An Old Laptop?

Back in November we asked what you would do with an old unused laptop. If you have an old laptop that’s not doing much more than gathering dust, chances are you could put it to better use. You could sell it, but you probably wouldn’t get too much for it. Donating or recycling can also get it out your hair, but if you’d like to try something different, read on for some ideas.
