Synergy 2100 DECT handset problem

[iBozz]

OK, this isn't mobile but it is cordless so maynbe you can indulge the slight tangent?

One of my Sysnergy 2100 DECT handsets now "overcharges", by which I mean that the charging unit continues to charge ad nauseam.

This has the effect of "locking" the handset so that it cannot be used - pressing keys has no effect. If I remove the battery and rest the handset it works fine - until it next gets charged at which time it overcharges again.

I have replaced the battery - no change. I have tried other handsets on the charger and they are OK, so it seems to me that it is the handset itself.

Is there a home repair which I can carry out - bearing in mind that I'm a telephonic technophobe?

Or is there an inexpensive repairer in the Central or South Manchester areas who could look at it for me? I did take it to one mobile 'phone repair shop and, although sympathetic, he said that he only did mobile reairs and not DECT repairs.

I can replace the handset for around £25 or so, so maybe it just isn't worth the hassle, but the Scrooge in me makes this enquiry the least I coud do!

Thanks.
