Hello Allan and thanks raymo, I did ring Bintel back and they both thought that the battery draining has been rectified but not 100% sure of it. So I guess I just wait and see.
Hi Allan, I don't think that Terri will mind us hijacking her thread.
I got a small on/off switch from Jaycar for a few dollars. Remove the front cover and drill a hole for the switch at the top left of the front cover
to the left of the control knobs. You only have to cut one of the cables that goes to the battery, and connect up so that the switch is in the circuit. You just need a smallish soldering iron and a little bit of extra
cable. The whole job took about 20 mins. I also use a rechargeable
9v battery. The battery lasts for many viewing sessions, providing that you remember to switch it off when not using it. If you should
forget you only have to recharge the battery, instead of having to buy a new one. A spare battery, and you're always up and running.

You can cut either cable that goes directly to the battery. The switch just serves to break the circuit to stop the battery draining. Just connect one of the cut ends to one of the connections on the switch, and the other cut end to the other connection on the switch, quite simple.
Of course, if the problem has been rectified, you won't have to do
anything.

I should be getting mine in a couple of days, will see how it goes.
