How to remove fix broken Apple Ipod Touch 4Th Gen A1367 Dock Connector

I would enquire regarding repair at: e-mail: [email protected]

The manual for your docking station should on its last page have contact information. I obtained the above email out of an online manual. This information is challenging to obtain. I hope what I have provided gives you some idea of what is involved.

There might be some issue with the docking ports. Try to connect a different iPod and see if its working, if its not working then there is some problem with the Dock connectors in the docking station.

I have a battery from my if-2 by Sonic Impact. My ipod connectionwent bad. Battery and charger available.

It is most likely the 30 pin connector on the Logitech that is the problem. They can break if the incorrect iPod inserts have been used. Try playing someone else's iPod on it, if no go it's busted. Repairs are difficult if not impossible. Sorry

No, but I have repaired many without a schematic. Aside from damage, there are abiot four basic failure modes. Tony

Get one of these to sole your problem. ipod change their charging circuit I found one at Walmart in the ipod accessories section. Its called the Passport home dock adapter.

- this accessory supports charging for the iPhone 3G, iPod touch (Gen 2) and iPod nano (Gen4) with most iPod docking stations
- Snaps into any iPod universal dock and accepts universal dock adapters

They do not exist. I was not given instructions with mine. Now its only function is an Ipod charger and speaker.
