Touch screen not working after replacement

hello! i have a iPhone 3G 8gb, and it got dunked int he toilet. Everything works on it except the touch screen, it is completely unresponsive. so i changed the touch part of the display as i always have with unresponsive screens, and it still doesnt work. I tried a firmware restore and that didnt work. I cant do the sensitivity increase because the screen doesnt work at all. i dont know what to do. Is the logic board fried? i can turn it on and the home button and volume/vibrate buttons work. i havent found any other solutions to fix this, im hoping i didnt spend 60 bucks for a touch screen and it not be the problem :(

I have, I double checked everything, and I've done this before to other iPhones. I tried restoring it, and everything. I'm wondering if the touchscreen controller is fried on the logic board. Is it possible they sent me a bad panel?

That's completely possible but usually I would expect water damage to be worse than just the touch panel. It may be that the touch functions of the logic board are fried.

Mine was not dunked into any water and I have the same problem!! What do I DO?

Looks like you asked the question :-) just delete this comment so that it does not get confusing.

I have the same issue..I have taken a working screen from another 3G and it acts the same.. It's as if something is not processing the input from the screen..

Mine aslo was a dunk in the toilet! Is this a motherboard issue or is there a replacable part for processing input from the touchscreen?

Well it does seem that the only broken part is the touch panel. Make sure you carried out the repair 100% correct.

Same has happened here, nicely smashed front glass, replaced the whole frontal assembly just to be "quick and easy", alas to no avail, touch screen doesn't respond, tried with old/original unit, still doesn't work either.

I fix a few iPhones/iPods a week and 3G (and 3GS) units are usually the simplest of them all, but this time it looks like it might well be an onboard controller fault :(
