Hello

I have a Sanyo 900MHz cordless phone (model CLT-9922). In recent
weeks, when I put it on the base unit to charge, I don't hear a *beep*
sound which confirms that charging is taking place. However, the LED
on the base unit does light up as if to indicate the phone was
actually charging. But I know no charging is taking place after
finding the phone dead after leaving it on the base unit for a couple
of days. The phone is just over a year old so the warranty is over.

The funny thing is, if you keep trying to put the phone on the base
unit, after the 20th time you may actually hear a *beep* and the phone
will charge.

What could be the cause of this behaviour?

Thanks in advance
H
