Has anyone heard of this issue with the tv?

The TV about 5 years old and has been doing it for a couple of weeks. It does it at completly random times, sometimes it wont do it for a couple of days, but other times it will do it every 5 minutes.

What happens is this:

The tv both the panel and the reciever unit both turn off, showing a red light. Then when you turn it back on the panel just turns back on and displays E01. The panel then turns off and flashes red.

We have talked to pioneer and they sent down some new system cables free of charge (good on them) but otherwise they have said get a new one or send it up to Auckland (I'm in Christchurch, and its really heavy!)

Any ideas? the pioneer people hve indicated that it is the reciever box.
