ET9500 Component output red touched

Help please guys,

Just bought a new ET9500 and flashed it to OpenPli latest software. After this I wanted to use the component output, but discovered that it had a red touch. I tried to switch to SCART in A/V settings, but the picture went black. It means there is no connection inside the ET9500 between the SCART and the Component outputs.

Please give me a hint what I could try..

Thanks.
