Anyone old enough to have played with an original Nintendo NES knows the problem: You plug in the cartridge, turn on the system, and get a blank screen and the power light blinks at you. The schoolyard fix is to take out the cartridge, blow into it, then put it back into the system. Then, with a little luck, you can play your game. The trouble is, that’s just a short-term fix. In the long run, it makes the problem worse and eventually the system can’t play games at all. The solution is to clean them. Here’s a process for cleaning NES games.

Cleaning N64 games is a controversial topic. It doesn’t have to be. There are some techniques floating around that can be harmful. But I also bristle when I see people say there’s one and only one right way. Here are some techniques for cleaning N64 games, based on my decades of experience fixing computers and game systems.
I had a Marx 999 that didn’t run well when I pulled it out of storage. When pushing it along the track a few times didn’t yield any measurable improvement, I decided I’d better take it apart and give it a thorough cleaning.
In this case, I worked on a Marx 999, but everything I did applies to any other O gauge train Marx made except for the very late 490 locomotives, whose motors don’t seem to have been designed to let you do any more than replace the brushes.
It probably was just a matter of time, but one of my sons dropped his Asus Memopad HD 7 and cracked the digitizer assembly. What we usually call the screen actually sits behind the breakable piece of glass, and more often than not, it’s the glass digitizer that breaks. I left it that way for a while, but once the screen cracks, the cracks tend to spread, and eventually the tablet will get to a point where it’s unresponsive.
Replacement digitizers are available on Ebay. Note the exact model number of your tablet (my kids have ME173Xs, so here’s an ME173X screen) because they aren’t all interchangeable. The part costs around $20. It took me about three hours to replace because it was my first one. If I did this every day I could probably do it in 30 minutes, and I’m guessing if I have to do another–ideally I won’t–it will take an hour or so.
Soldering is an intimidating skill, but it can be learned. And with some practice, it’s not difficult to learn how to solder.
I’m not a professional. A lot of people are surprised to hear I’ve ever had to solder on anything computer-related, since many people my age haven’t. In spite of the disadvantages, I learned how to do it. If I can solder things that will hold together and conduct electricity, you can too.
Here are some tricks and tips, most of which I’ve learned the hard way.Read More »How to solder
Evening update. I came home to a non-working phone and CD player. The phone’s working again. I’m thinking Southwestern Bell really doesn’t want me to like them. As for the CD player, I unplugged it for 10 seconds and plugged it in–first thing I do with any piece of electronics. That brought it back from the dead, but as I was listening to U2’s All That You Can’t Leave Behind, I noticed some crackling in the audio. I’ve been listening mostly to really synthy New Wave music lately and the crackling can blend in with the synths, but on the more organic-sounding tracks in the middle of ATYCLB, there’s no place for the crackling to hide.
I ought to open it up and see if the problem isn’t just an overly dirty lens. That’s nothing a foam swab dipped in a little isopropyl alcohol can’t fix. Otherwise, I may have to start shopping. That’s what www.audioreview.com is for. The JVC XL-MC334-BK looks good for the money.
I’ll also have to resist the temptation to get a second pair of speakers. The KLH 970A speakers are dirt cheap ($20-$30) and reportedly sound really good for the price. There are better speaker brands than KLH, but these would be secondary speakers and if I don’t like them on the stereo, if paired up with an inexpensive receiver they’d make a very nice computer sound system.
An early Christmas present you don’t want. Another e-mail worm is making the rounds, this one called Navidad.exe. Navidad.exe es muy mal para su computadora. Sorry. Couldn’t resist.
What it appears to do is reply to all messages in your inbox containing a single attachment, attaching itself in the process. The really nasty part is that the worm contains poorly written code, causing your system to be unstable.
I’ll continue with my standard advice. Don’t open unexpected executable (.exe) attachments. If you can’t tell the difference, don’t open unexpected attachments at all. It’s better to miss the joke than to have to reinstall Windows yet another time. Keep in mind that the people who are most likely to fall victim to such things are also the least likely to have any backups.
You can get details and a repair tool from Symantec.
A friend got a hysterical phone call at midnight last Thursday from another friend whose system was exhibiting behavior similar to this. He eventually calmed her down enough to walk her through reinstalling Windows, which restored her system to a bootable state.
If a system will no longer boot, it should be possible to bubblegum it back together with Windows 98’s scanreg tool. Boot to a command prompt by holding down the control key, then type scanreg at the C:> prompt. Restore a recent backup (preferably the most recent or second-most recent). Once you boot successfully, immediately update your virus signatures and run your anti-virus program, or download a repair tool to do a full repair.
This trick fixes many, but not all, recent viruses.
