charging light blinking, no display
hi, another day another problem. My multimeter is without battery so I am unable to test continuity or battery charge. This phone belongs to a friend and he's asked me to try and fix it..this is not a phone I am selling which is why I ask (usually I will do my own research but this time I haven't found a solution)(and no this is not the complete piece of junk I did buy today!)
His story is the phone suddenly turned off. When I connect to mains charger you get a solid red light for about 30 seconds then the red light blinks four times, then off for 4 seconds. No display, no warmth on the battery. I have checked the pins for the dock and the battery, visually look ok. Taken the phone apart, the tab for warranty was still intact, no idea where water sticker may be but no signs of corrosion.
What I've tried so far... put on charger, battery removed for a few minutes then replaced (got that idea from a forum) plug in to mac, hold power button for very long time (also from forum)
I've put the bb disc in the mac, but think it's a windows thing.. am I wrong? either way the mac didn't see the phone via USB but the red light is now constantly on.
The forum mention that a completely dead battery needs to be "trickle charged" back to life..
no.1 buy new battery..... any other pearls of wisdom? As you know I fix iphone 3G's so this is not my thing. Any help or advice greatly appreciated.x
