Just bought a Philips 32PW9308 and the picture appears to be tilted down on left hand side. The engineer said this can't be fixed and has offered to show me a new batch of these when they come in in september. He said if they are all the same I'll have to live with. If they are not he will replace. Is it true that this can't be adjusted? I have gone through the service menu and nothing seems to change it. Any ideas?
