The Tinker

the remote may have dropped and there are 2 possibilities of fault.
1-acrystal which gives accurate frequecy was broken
2- the infrared sender led was burned or the printed cicuit connection for this IR led is broken

The battery is rechargable for about 400x. If you leave it on the charger too long or never let the battery run down it will shorten its life span. Sonic Impact no longer sells the replacement battery unit through their website and I have been looking for replacements myself. the problem is this: the battery unit is integrated with the battery cover and can not be separated. So you need the actual Sonic Impact battery, and they have not responded to any emails, requests for customer support or phone calls. Good luck.

If you have a later IPod, 6th Gen or later, Apple changed the software and Sonic Impact no longer plays your movies, but audio is fine. You can get around this by purchasing, from Apple, and adapter cable. It is $50 but allows you to charge your Ipod and play your movies on your home TV. The cable is really just a key that unlocks the TV Out setting. If you have and 5th Gen or earlier then you probably just need to go into video setting and select TV OUT : ON. I hope this takes care of your issue.

Absolutely, I have this myself. My 5th Gen works great, but the 160GB would not show movies, just played music. Apple has an adapter cable set that allows you to hook your Ipod to your TV. $50 buy it! You can charge and watch your stuff on your flat screen. It also unlocks your Ipod TV out setting for your Video 55. Set you IPOD video setting to TV Out: on, select your movie and play. Plug in the IPOD nip to your Ipod then set your Ipod into the Video 55. A bit of a pain but works flawlessly. If you select a different movie you have to do this all over again.

Hey how do I find a replacement battery for the Sonic Impact I F2?

You need to switch the video out seeting on the iPod, simple. It is located in Video/video settings/TV Out. Change the setting to "On". Problem solved. However, if you have an iPod that is less than 1 year old, nothing will work, iPod blocked this ability to change to "On" and is set on "Off" permanently.

Take a look at this web site for Sonic Impact. This may provide an anwer to your problem.

Try this if you haven't already. On your iPod select Videos then Video Settings and see what option is selected for TV Out. There are 3 settings On / Off / Ask. If it is OFF click the center button to change to ON or ASK and try to play your video file again. If that does not work take a look at this web site for Sonic Impact. It has a message about changes to iPod software.
