What brand is your rear hub? You will need to know that for both the proper tool and to get the replacement gears. With an 18 speed I would assume you have a 6-speed rear sprocket. I like Alan don't work for Park but I have been using their tools for over 20 years to work on my own & friend's bikes. You will need to determine the freewheel brand you have and then select the proper freewheel removal tool, most of the freewheel removal tools can be found for around $10-$15 but you must use the correct one or it's really easy to do some damage. You will probably need a chain whip as well to complete the job. If you haven't done much bike maintenance and want to learn, that's a good project to start. I have read a lot of books out there on bike repair but the best I have seen is the Park BBB-2 "BIG BLUE BOOK of Bicycle Repair", it has really good pictures and explanations for just about anything you would want to do as well as it shows you how the tools work.

Does your audio system support video switching or is strictly an audio device? Some of the systems will handle the video switching but will not pull the audio from the HDMI cable (I have an older Bose LS 38 system with the external video switch which only does video). I don't have an XBOX-360 but for my PS-3 to work I use the HDMI to send the video only, I configured the PS-3 to output the audio via a fiber output it has, my system will accept that for the audio and it works fine but it did have to be configured. Does your home audio system have a digital audio input using a copper RCA type jack? If so they make converters that will convert from the fiber connection to the copper digital connection. If your receiver does not have some type of digital surround input, it won't take the digital from the X-Box.

Alyson, Along with what oldturkey03 mentioned has your connection ever worked? Was an update performed on your PS-3 or was someone going through the menus’ and possibly changed a setting? Do you have the ability to try a wired connection? If you can, that would be the easiest to verify your connection through your router is working. You should also verify your Internet Connection is enabled in the PS-3, check the menu tree (Settings: Network Settings: Internet Connection: Enabled). Are you trying to use a static IP address or are you using DHCP (automatic assignment)Without more details on how you are trying to connect and your router type, it will be hard for us to give you any specifics to check. If you are using wireless we will need to know what type of encryption you are using and any security settings on your router/access point. Rich

I had a problem with mine, we had a momentary power outage in the house and after the power came back on the Wii did not even light up. I unplugged the Wii and plugged it back it a different outlet. No help. Then I unplugged it and left it unplugged over night. The next morning when I plugged it in it worked fine. I spoke with some co-workers who also have Wii's and I have found that this can be pretty common. Anyway it's working fine now.

I worked on a lot of CRT screens back in the 80’s. That rubber cap on the back of the CRT is where the voltage from the fly back transformer comes in. WARNING: THIS VOLTAGE IS HIGH ENOUGH TO REACH OUT AND TOUCH YOU! Do not try to measure this voltage with a standard multi-meter; you have to have a special hi-voltage probe, which is long and insulated. That extremely hi voltage is needed to push the electron stream across the vacuum space in the CRT; I have seen in excess of 40KV on some systems. We used to use a long flat blade screwdriver with a ground cable attached. Push the screwdriver tip under the edge of the rubber cup, you may see a spark. Then it would be discharged. If you are disposing the CRT it should have the vacuum pressure released. To release the pressure there is a metal connector under the rubber cup. Once the CRT has been discharged, disconnect the connector under the rubber cup. You will see the little metal connector nub underneath. You can cut that with diagonal cutters and you will hea...
