My first attempt at replacing my 5th gen’s hard drive with an SD card resulted in the red X screen, I replaced the ribbon cable and that did it. Anyhow, according to a few blogs I read, the HD, ribbon cable, or battery can cause that error, all are pretty cheap on ebay. If you think the logic board is fine, I would replace all 3, maybe even the headphone jack as well since it’s also cheap and you’ll already have the device open.

My iPod 5th gen 80GB video seems to have a playback issue only when using the 30 pin connector in my car. During playback it will randomly and very briefly hesitate or cut out, the problem does not occur when using the headphone jack and it doesn’t seem to be isolated to any specific tracks. I have a second 60GB 5th gen running Rockbox, I restored it back to factory settings just for testing in my car and it does the same thing, only while using the 30 pin (yes I tried a different 30 pin cable). When using a newer iPod touch in my car the problem doesn’t occur, I don’t see this as a solution because the 5th gen sounds so much better. Anyone else having this issue?
