damage HotSync cable causing excessive hot

one day, one pin of my HotSync cable is broken, so it cannot attached firmly into my treo650.

So while charging, if the connector not firmly plug into the handheld, for several minutes it will become hot and hotter. and later the LCD display will turn dark, and the treo will be hot.

to make the LCD to be normal in instant, first press the Function button (the big dot button on the left) than press the P button to show the brightness menu. after the brightness bar showed, scroll to the right and back to left again to restore it bright.

but there's no way to cool the gadget instantly. so you have to wait several minutes to make it cool.
