bac is correct with the link... The Red X and Red Circle is seen only on the iPod classic. If the suggestions on the website do not help, then this means that the hard drive is faulty and needs to be replaced. I've seen this when working on customers iPods.

Take a look at the top of your logic board by carefully undoing the display cable from the logic board Link text. You do not have to remove the entire display or remove the front panel to see the model number under the cable. If it says, "820-1763-A", this means that this logic board is the first generation iPod video... and meant only for the 30/60GB hard drive models, and it will not support an 80GB. If it says, "820-1975-A", this means that this logic board is the second generation iPod video (5.5)... and can work with the 30, 60 and 80GB iPod video hard drive (maybe even high size hard drives, but I have never tried this theory). Besides it being able to use an 80GB hard drive, it has the Search feature/option on this board. I do not know why iFixit doesn't state this fact. But I made the discovery after repairing many iPod videos and had the same problem.

Try detaching the hard drive from the logic board, then reattach it. Link text When the iPod is starting up, do you hear clicking? This is a sign the hard drive is failing, or has failed. Try restoring the iPod by putting it into Disk Mode: http://support.apple.com/kb/HT1363 If none of those work, then try placing the hard drive in the same iPod model (if one is available) to see if that working iPod sees it... And vice versa. If the hard drive is good, then you can bet it will be the logic board that needs to be replaced. Make sure you replace it with the same model number: 820-1763-A or 820-1975-A.

This means that the headphone jack is becoming faulty and needs to be replaced. Simply locate the size of your iPod video and replace the headphone jack/hold switch. Very easy to do.

Try connecting it to a wall charger to see if it forces it to turn on. If successful, it could be the battery. (Even if it starts up, it could still be the following...) If no luck, then it could be the logic board or hard drive... or both.

Same thing happened to mine after it was tossed (by someone else) and hit the headboard of my bed. I can still get audio without headphones, but with headphones-- Nothing. The headphone jack is soldered to the logic board instead of it being a separate piece like earlier iPod models. And so, in order to replace the head phone jack in the iPod touch, you have to replace the entire logic board. Try backing up your iPod with iTunes and then restore it to that back-up copy. If it starts working, it maybe a software issue on the iPod touch. If that does not work, you can always try restoring it as if it is a new iPod, but then you would loose all your data and settings on the iPod... But it is still worth a shot.

First, try restoring the iPod. If that does not solve the problem, then I do not think that it would be the hard drive, it would be the logic board since that is the device that controls how the iPod functions when it is turned on.

First, try restoring the iPod. If that does not work, try opening the iPod to see if there is any damage or corrosion. I have also had it that once I opened the iPod, detached and reattached cables, the problem goes away. If still nothing, try another click wheel. If that still doesn't help, then the final thing it could be is the logic board.

Detaching and then reattaching the original black tape on the hard drive (when replacing the hard drive and/or hard drive cable) may not be easily reattached later. This is okay.

(Optional) You can use black electrical tape to hold the blue bumpers back to the top of the hard drive cable (after the cable is connected to the hard drive). 1/2" of tape should be fine for each side, and placed equally over the top.

You can also gently use a metal spudger to lift up both the top and bottom bezels. Allow only 1/8" of the metal spudger (like the screwdriver in the picture) to get inside to get leverage, before fully lifting the bezel up. Please note where the little "teeth" are underneath the bezels, or you can damage those if you are not careful.

Also, using too big of a flathead screwdriver can cause damage to the plastic and chips away plastic from where you were trying to pry up the bezels, ruining the look of the iPod.

If you need to, place the fingernail of one of your fingers, or use a spudger, to hold down the base where the iPod battery is connected. Take your time and have patience too. Using too much force can separate the base and ruin the logic board.

Don't do this unless you have to. Getting this ribbon back in is nearly impossible.

Try using tweezers or medical clamps to reach in that tight spot. Use these tools to also connect the click wheel ribbon back to the logic board.

Be careful when you are trying to remove a working display from the nano it came on (when replacing the faceplate as well). Because of the adhesive, too much force or pressure can cause the display to crack and cause the display to "bleed"... resulting in replacing that part if it was still good. Try using a hairdryer to gently warm the adhesive to then remove the display. Warning: Too much heat can also ruin the display or melt the front panel.

If you are use to fixing the 5G iPod (video) logic board by gently prying or lifting the board up, and you skip this step #34 or try to gently pry the board up without removing the two screws-- You can damage the metal frame and/or the logic board.

If you know the ear buds or head phones are good, and no audio can be heard from the audio jack or when the iPod is placed on a docking device (ie. iHome)-- The problem may be the Logic Board.
