I would try holding the home button and hold button at the same time while its connected to the computer for ten seconds. If the ipod powers off and turns back on with an apple symbol then your ok. If it turns off but doesnt come back on in less than 6 seconds youll need a new back light i.c. The i.c. cannot be removed without a hot air knife because it uses pad undermount solder joints not accessible with a soldering gun. I explained it above in earlier posts... -Adam

Hello, I took a picture of a broken one I am using for parts. The IC is removed but you can see where the solder pads are. There are six small pads and two larger pads between them. They are located just below the circular pad trace. Hope this helps.

The iphone 4 backlight IC is the same used for the 4th gen Ipod Touchs and is the same one also used for the 32gb and 64gb 3rd generation Ipod Touches as well. Be carefull when you take the EMI shielding up on the circuit board because Apple uses independent grounding system and uses the EMI shield to connect the grounding nodes around the edges of the circuit board together. It may run without it on, but now your in violation of FCC regulations and if there is a static discharge internally in the ipod the circuit board is at risk because it is not properly grounded. My suggestion is using a Soldering Iron and Chemi-wik to remove the solder that attaches the EMI shield to the circuit board. This way when you are down removing the old IC and replacing it you can re-secure the shield back to the circuit board. Just an idea of correct tools if you do this a lot. I use a Hakko FX-951 and FM202 soldering station with controlled heat and interchangeable tips for different applications. Resin Solder and...

I have done extensive Ipod repairs for the 1st generation through to the 4th. I can tell you from experience that the backlight is not in the LCD. I am also an electrical engineer, so what I am telling you is not b.s. The 2nd and 3rd gen Ipods for the 8gb and 16gb use a JL9 or a 109B/109H backlight. Look that up on ebay, under iphone backlight. cheap part, you need an air knife to replay the IC though because the IC is a surface mount technology (SMD) type and there are two pads under the IC that need to be soldered and cant be reached except by hot air. Now the 32gb and the 64 gb version of the 2nd and 3rd Gen Ipods use a different Backlight ic from the Iphone 4 or 4s. The part number is 1TN. It is slightly smaller than the 109B/109H production line but still functions the same. The 109B/109H are located near the bottom left of the motherboard, and the 1TN is located under the steel casing on the back of the motherboard on the top right hand side. You must pull the steel up in the corner to reveil the IC....
