Cannot see TV through digital box on my sony trinitron

The BG-1S chassis has a BNC video input socket and a high impedance audio input socket.
It was built in 1999 and I am sure we didn't have digi boxes then.
You have a choice; Purchase a BNC/Phono to whatever socket in in your decoder/dvd thing or purchase a new TV.

it could be the signal strength for your cable isn't strong enough. alot of people are encoutering similar problems ever since the digital switch over

Have you connect all the component video out cables from DVD to your WEGA TV? if so just set your tv to dvd input.

I think you may need an RF Modulator. This device will have connections for the DVD and TV and will have a channel 3/4 switch. Good luck to you.

HOOK THEM UP SEPARTLY,,,DVD COMBO WITH RCA JACKS

Have you tried playing the DVD in PAL60,NTSC 3.35 or alternately select the colour system on the TV manually rather than in auto ?

audio/video OUT from the cable box to the aux IN on the panasonic right? So you can see the output from the cable box but only sound from dvd. Are you changing the input on the tv when you go from watching the cable box to watching the DVD? the panasonic handles audio, but the video from each goes to two different inputs on the sony. I hope none of this sounds condescending.

you need a digital coax cable and then connect it to 6.1 also the digital cable type is not a coomon type so check that also

This is an Analog TV - you will require converter box.
