ok, The issue will be in the sequence you have things connected. The connections sequence is going to be controlled by what connections are available. I assume the Set Top controller is connection to your Antennea connection on the TV. Your TV should be on channel 3 or 4. The next step depends on what type of connectors you are using for the JVC DVD. I have an Antennea output on mine so I connected them in series. If you don't have an Antennea output from teh DVD player you will need to connect the DVD using Audio/Video cables which means you will need to connect to the TV alternate Source connector and to watch DVD's you will need to change to that source. Much like you would switch between regular TV and VCR tape on a VCR player connected to the Antennea connector.
I hv philips 21RF vardaan TV ,there is sound on AV channel. and the picture is blinking. even some menu setting have changed.. i tried using the service menu but cudnt understand anything. 2 new av channels have come.. av2 and front which were not present before. sound is not coming even on the other channels but picture is fine on them. only on the av1 channel it is blinking., the philips technision had solved this prob once by pressing some code by remote and i don't know the system code
Try plugging your cable box in using a/v cables (red,white,yellow) and see if you have a picture on a different input from the box. If so, go into your general settings in the box and change the output channel to 4 instead of 3. Then try your TV on 4 and see if your picture comes in. I have seen TV tuners go out on just one channel before.
delma11-If your AV was working good before,it is quite possible the AV jacks are cracked away from the pcboard ass'y. If your tv goes into AV mode,try wiggling cables to see if picture comes in.You could also try changing patch cable,let me know if this helps. cooltek Feb.16/08
