I can find no useful information on a NEC FS-6802 television.
What digital camera are you connecting to the TV (camera make and model)?
How are you connecting to the television?
...AV with RCA connectors, S-video, HDMI, component
Is the television a flat panel TV (if so ... plasma or LCD), or is it a CRT screen.
Does the television have digital or analog tuners, or both?
My NEC TV model FS-6802 Video In system is NTSC. Video out on my camera is also set NTSC , but photos on TV show in black and white. When I change video out on my camera to PAL, I get colour but the colours are wrong and the photos are fuzzy. Is there a remedy?
