I was going to check the LCD and forgot to turn off the iphone before taking LCD From logic Board . returned every thing back but iphone doesn’t start , iTune not recognize it , I used all methods to reset but no chance Did I fry the Logic board by not turning it off before taking apart? can this be fix? thank you Update (01/23/2011) I got it today Form repair shop . they told me that Motherboard was effected and they change some IC on the Board , i don’t know whats that , but its working fine , i opened the phone and its same motherboard and same LCD . i don’t know what they did actually
-Check contact points for burn marks. -Test LCD in other iPhone -Do a hard reset as well -Flip ringer up/down to see if vibrator responds
