If the E-W alignment is ok on some modes then it means the circuit involved is working ok. This means you have a software corruption problem. If you look around the back of the set there's a socket to connect a computer to adjust software. Philps dealers also have a service remote to do the same thing in a customers house. I'm afraid your only cure is to contact a dealer, your local friendly (cheap) engineer working from a shed in his garden probably won't have the gear to do the work.
