Onkyo TX-SR309 switches of first time use

[revoldius]

I have a onkyo TX-SR309 MK2 which switches of when you first use it. When you switch it back on again it works fine, and keeps working fine. I know there's a secondary power supply which switches on the main power supply. So I need to look for the problem in that region.

Also if certain lights in the house get turned on or off the picture freezes. I'm suspecting there's a problem with filtering in the power supply.

Has anyone had this problems before?

Sounds like a problem with your house wiring if lights are affecting sockets?

it's only the lights of my aquarium which cause the problem, they are fluorescent lightbulbs.

traditional tubes with ballast and starter?

because they spike the mains when they start and it may mean your main capacitors are worn out.

was Affraid of that, could that be the reason that the receiver shutsdown?
