I tried to set up my 990 yesterday, and I believe the unit is either locked up or (mostly) dead.
I connected my VCR, DVD and cassette players. TV is connected via the composite output. I configured the sources using the on-screen display, so I know I have a viable video output from the 990 to my TV.
First problem. The remote never could turn the 990 on or off. The menu and navigation buttons worked.
Second problem. No video for either of my sources. I had a video tape in the VCR and a DVD in the DVD player running, and I could not get an image.
Final problem. Now the remote does absolutely nothing. Put in another set of batteries just to be sure. Also, the 'Input' button on the 990 no longer changes the input. The AM/FM radio works.
So either the unit is 'locked up' or mostly dead. Is there a 'reset' function somewhere? Any other ideas?
Of course, telephone support is offline for the holiday weekend...
