iPod will not Power on after screen replacement?

The above is correct, replace the flex cable. I want to note, however, some soldering tips. It seems that second to ripping the flex cable people tend to destroy their logic boards by tearing off the solder pads where the flex cable connects.

1. Put Kapton tape over the nearby circuits to protect them when doing any type of solder work.

2. Always use a solder braid to push off/desolder/remove the old cable. I use a chisel tip for desoldering the flex cable with a braid, however, I use a fine conical tip when soldering the new flex cable back to the board.

- I've seen too many tutorial video showing people heating up the flex cable contacts and pulling it up. It is easy to apply too much heat -- and if you pull on the cable you can easily lift the solder pads. There are tons of "boards for parts" on e-bay and probably 99% of them have lifted solder pads.

I usually suggest that the + terminal on the battery be desoldered first to prevent shorting out the board from accidental solder splash, etc.

Lets us know how you do!
