Can Backlight be Repaired?
My sons iPod went through the washer. It still works except for the backlight. It will sync, it will unlock, play sounds, etc just just no backlight.
Warranty is useless so I've got nothing to lose. I haven't found a "6R8 coil" like repair for the 4th Gen Touch.
If I need to replace an entire board, which one? If there is a component to replace, which one? I have the skills to do the work, just need an idea where to start.
Thanks!

@oldturkey03 Depends on what you mean by the backlight or LCD. I see no backlight at all in this Touch. If I put a flashlight on the screen I can see the icons on the LCD, can navigate through different apps and settings, and verified that the brightness settings are at max with auto brightness both off and on. Any settings here change nothing and seeing what is on the screen is unchanged.
I appreciate any ideas you have. Believe me, you aren't going to hurt my feelings. The IC that you have pointed me to is a good idea, unfortunately the pics point show locations on an iPhone, not the iPod (if it exists).
With nothing to lose, I took the unit apart tonight got out the alcohol and cleaned like a mad man. Got it all back together and no change. Unfortunately I failed to see your post until after I got the unit back together. Had I read up beforehand I could have looked for a similar IC. Too bad it's unmarked.
Again, other ideas are appreciated. I wish there was a way to determine if the LCD/LED sandwich was faulty or a component on a board was bad. I have sent this unit into iRESq and they said it wasn't worth the repair. Had I been smart I would have asked for more details, was it the mainboard or the LCD. I should call them back tomorrow and find out. I'd presume the mainboard.
It's kind of a bummer how little info there is on these units when the iPhones and previous gens of the Touch have tons of info.
Thanks again!
Es esta una buena pregunta?

Mike Campa, yes Apple takes the security about their IC's very serious. It is a silent, black helicopter affair and its tough to get some good chipset information on the newer equipment. Sorry about the link, must have been half asleep when I posted it. I am still trying to get more info and will let you know ASAP

So I've seen conflicting information, can the backlight be pulled out of these or is the sandwich of backlight and LCD all one part. I'm guessing it's a one piece unit as I don't see replacement backlights out there, just replacement LCD's. If I knew the pinouts I would try putting a bit of power to backlight which I believe to be an LED backlight not fluorescent, but that info has been conflicting as well.
Anyone know the real details here? Anyone know the pinouts?
Thanks Again!

To get the pinouts is even more impossible than to get the info on any IC. It is my understanding that the backlight is part of the LCD and the inverter circuit part of the logic board. So in your case an LCD change should resolve the issue. Good Luck

I am really interested in this. I have replaced my daughters ipod touch 4th gen screen but it wont light.
Exactly the same description as you have but no way this could have blown the logic board as it was definitely not powered up when i was working on it.
Have tried different screens all with the same problem.
Mike, how did you power up your backlight with a battery? I am a technician so well used to soldering and playing with tech kit. Many thanks, Ian.
