iPhone 3GS does not power up?

When plugged into household current and the power button is pressed the white Apple logo appears onscreen briefly then disappears quickly. I am thinking this could be a battery problem but the battery is only four months old and showed 80% - 100% charge before this happened and it was installed by a professional iPhone repairman, however perhaps it is a defective battery and I got the only lousy one out of billions of good ones produced? Not likely but then on the other hand I could be struck by lightening. Is it an IC power problem? Sorry for being an idiot but what does IC stand for? (I hate acronyms!) Can you run an iPhone 3GS on household current only when the battery is dead? Will it even power-up?

Idiotwind, IC stands for Integrated Circuit. that is usually reserved for the "chips". You may be talking about AC which stands for Alternating Current (versus DC which stands for Direct Current.) For simplicity reasons, AC change the polarity of their poles i.e. Negative to Positive and vice versa at the rate of 50hertz (50times a second) again this is in very simple terms and may get me in trouble with some of my colleagues on here. Anyhow, when you are talking about household current, hopefully you are using an AC adapter. It converts household current to the power requirement of your device. It is possible that it is your battery, but your phone should not shut down on AC adapter power. Clean your dock connector, check for broken and bend pins. Try a different cable as well. You may want to try to place it in DFU mode and do a restore. If your phone does not show anything when you plug it into your computer. do consider to replace the battery again. It is possible that the battery you previously installed was new, as in never installed, but may have been old stock and no longer holds a charge. Hope this helps, good luck.

Thanks oldturkey0...I wrote up a long reply but when I went to send it this system rejected it (like the idiot in my username, I typed it in the wrong place!) but just wanted to acknowledge your kind assistance so thanks again and I will follow your advice.

...I forgot to ask, how do I place it in DFU mode and do a restore? I'd like to do a hard reset but can't do that with power, of course.

...I meant, do that without power...(I've gotta learn to check my messages before I hit the comment button.)

I read your other post also and appreciate the help. Replacing the "chip" is way out of my league I'm afraid and if that is the problem then my iPhone 3GS is toast. I mean by the time I buy the chip, get an iPhone repairman to do the "hard labor" and all that entails, probably have to buy a new battery (the repairman charges per issue resolved), I might as well buy a new or good used iPhone 4, which was the iPhone repairman's initial advice and he is more'n likely right. You know, I'm gettin' to respect that guy more'n more! :-)

Here are some great instructions about the DFU mode. :-)
