Thanks for your advise folks

but the camera was purchased in July and i bought it from a colleague a work

she had used it once on holiday but didnt like the view finder (shes old school likes the small eye finder)

and i worked perfectly thought it was sand but tried the blowing on ,hairdrier trick didnt work

The shop did mention they would have given me another one but they didnt have one in stock

what should i do?

should i go back to the shop and demand a replacement?
