Onkyo 606 stopped Upconverting ?

[admin_exported]

Is it possible to accidently turn off the video upconversion ?

My system is Sky+ to Onkyo vai svideo, ps2 via composite, DVD via hdmi and onkyo hdmi out via hdmi to TV. All was working fine until last night when my son said he could not get a picture for the ps2. I then could not get a picture for sky but the DVD is fine. Went direct from sky to TV and fine, added an svideo to the monitor out on the amp to the TV and picture fine so I know the cables are fine. Any suggestions apart from performing a full reset on the Onkyo ? COuld the onkyo have developed a fault ?

Thanks

Sorry cant be of help! Am after a bit of knowlege, when your system was working was the sky picture on your tv better through the onkyo than direct to the tv. IE does the upconverting really work?
