I have just replaced my lcd/touch screen with a good proven suppliers part, and now the proximity sensor will not work. I...

where is the signal antenna on a iphone 3gs logic board thanks Dave.....

you have burnt out the speaker with water damage

This is how I stripped my very first iphone a long long time ago. I got a piece of a4 paper, and with a ruler and pencil made a rectangle shape on the paper to replicate a phone. I then took out each screw, and placed it on the paper and stuck a piece of selotape over the screw to stop it moving , and marked each screw to where it came out of, ie camera charging docketc etc. The first phone i stripped was a 3gs, to replace the rear case.when i bought the rear case and fitted any parts (volume button) that had to be put on before the bezel could be glued on to the new rear case.I then put the phone back together with no problems whatsoever, as i knew every single screw went back exactly where it came from. If i were you, i would buy a brand new complete screw set around £2.00 in the uk, and then go on you tube and study as many stripdown vids as possible, and the reversal of that same procedure, and if you take your time, you will get it back together..Keep away from a repair shop, as they will charge a...

I have just replaced the mid frame on a 4s, which is a bit more work than the 4, but I totally agree with the other guys,if you have not had a @!*% of a lot of experience inside a phone, then get someone to do it for you,as it is, as the guys say a total strip and replace.to be honest it has to be THE hardest repair on the 4, as nothing else entails this amount of work rgds dave..

I would say it is def not the battery, but the power on/off flex.I have had this problem lots of times with different iphone 3gs.The flex is relatively easy to replace, and you will see when you buy the new flex that the silver shield behind your power button has flattened, and thus makes it hard, and in most cases impossible to switch the phone on, as the flex has broken down at that part.I would guarantee when you plug into itunes your phone comes on, backing up what I have just said.It (the flex) comes from the power button down the side of your camera, along the top of the battery is part of your headphone jack,volume button and mute button. hope this helps rgds Dave (uk)

Hi, if you look at the end of the logic board near where the two connectors for the screen are, it slides on the end of the board.I assume its to stop the board damaging those flex's, but i never put it on, and it dont affect anything.If you want to be on the safe side stick it on with a tiny bit of double edge tape or superglue.I would imagine its better on than off rgds Dave
