No need for a new one now. The fault was a hairline crack in pin 4 just as
it entered the body of the chip. Tricky to see with the naked eye. But when
moved it could clearly be seen. Added some silver solder with tiny 1mm tip
and hey presto it works perfectly again.

Cheers Paul: great job!!

Most difficult fault I have ever had to diagnose in 15 years of fault
finding on electronic equipment. Replacing the chip seemed the only option
till I saw the crack.
Damm cheap Taiwan components, just not built to last.
