Question about Toshiba DR4 DVD Recorder

Diagnal Interference Lines

Regardless of my hook up method, the lower channels (usually 3-12) render the picture unwatchable due to rolling diagnal lines across the screen. When I bypass the DVD-R the problem is eliminated.

    Diagonal, sorry about the spelling. So I bypassed my cable box and the problem was eliminated. This confirmed I don't have to send the DVDR in for repair. I thought I checked my coaxial cables previously, but I replaced a very long cable with a shorter one and the problem was rectified.

The diagonal lines represent some low frequency interference (close to the supply frequency - 60 hz). Try to keep the unit away from other appliances, especially the left back zone - where the tuner is. Also, you have to do some experiments on the cable connections: disconnect other cable devices (internet modem, home phone, other tv/tuners), one of them might inject these signals into the cable. Keep me posted

Does the handle position have anything to do with the robot working

When the cleaner reaches the water surface the direction it travels to scrub waterline is dictated by the direction of the handle. The handle should be at a diagnal to the cleaner. You should reverse the direction of the diagnal frequently to prevent the cord from tangling and kinking. Cord should also not be coiled up tightly during storage.
