I noticed the other day that my son had a new i phone. I asked him what happened to the 1 year old Galaxy S he had. He sheepishly said its dead, I spilt a glass of water on it. Hmmm, thinks I, probably beer. Anyway I got the phone and tried it. Yes its dead. So in my retired boredom, the other night, with a loupe magnifier strapped to my head I dismantled it. Seemed to be white powdery substance all over inside (thinks? I hope he hasn't dropped this in the pee trough in the pub). undeterred I proceeded to clean all the circuit boards with a soft toothbrush and a cotton bud with WD40 on it. reassembled and tried, still dead. with the back removed I tested the on/off button with my DVM, that seemed ok but there was no positive feed to the switch. I then, with a piece of wire linked the positive contact for the battery to the other side of the on/off switch and the phone switched on and worked perfectly. I then got a single strand of fine wire and soldered one end to the switch and the other to the copper connector for the battery positive terminal and covered the surrounding area of circuit board with small pieces of sellotape for insulation and the phone now works perfectly. The whole operation was done with tweezers, a small soldering iron and magnifying apparatus strapped to my head.
However his mate now wants to purchase this phone for over £100. My concern is What happened to the original positive feed to the switch and is what I have done ok?
