Looking at pictures, your DVD/VCR has standard RCA red-white-yellow inputs and outputs. Can't find info on your TV, but I would say - if DVD works, it means your TV "sees" your DVD/VCR, so for not vorking the problems is internal to the unit, not to the TV or the connection.
I Have a Sanyo Model DP46848 TV & a Funai model ZV427FX4-A DVD Recorder/VCR. What cables are needed? How do I hook them up, set up both the DVD & VCR so they will both work? The DVD part works but the VCR doesn't. I don't have internet or cable service. Thank you!!
The VCR may only output via the AV connection.
The DVD would output via the HDMI or the AV connection.
Leave the DVD/VCR connected via HDMI for best picture on DVDs. Add the AV connection for VCR viewing.
