Customer Question

Model number TH - 37PX70BA. Purchased November 2007 from XXXXX XXXXX High Wycombe.

I have a problem with the AV2 input 

The picture in AV2/AV2S "mode" is almost a negative version with purple colouration at
the edges of people, cars, furniture etc.

As this is my DVD recorder input, I cannot use the "rec" or "dir TV rec" buttons on the 
DVD recorder remote control as I will record this horrible picture. 

Playback of timed recordings are unaffected & good.

The pictures in AV1 and TV modes are as good as usual.

When one changes AV1 to AV2 or COMPONENT etc a graphic appears at the top left of screen indicating which "mode" has been chosen.

For AV2/AV2S my screen shows "AV2-S-VIDEO".

I do not believe that is what it used to be but cannot be sure.

I have used the book to try & change it but without success.

Thanks
Alan XXX

 

Optional Information:
Make: Panasonic
Model: TH-37PX70BA

Already Tried:
Changing the AV2 mode from AV2-S-VIDEO to AV2-RGB but it reverts back. Checked all plugs.

I am not using the "component" input , I just used that as illustration.

 

AV2 input is scart

 

DVD recorder scart is AV1

 

NB this setup has been working for the last 3 or 4 years, it has only just started playing up.

Hi Alan

SVideo is the luminance and chrominance the black and white and colour combine so its a 2 piece transmission, somehow the set is reverting to SVideo because it thinks that the output from the DVD is SVideo which is available on the scart, however the TV set itself may not be have within its circuitry (although its flagging SVideo)the ability to deal with this signal (its poor quality anyhow) this could be because of dropouts in the firmware on the TV itself
Having said that you should not be using scart anyhow with a DVD it should be the far more superior "component"output and analogue sound or optical digital sound if teh DVD has optical out, so your looking at 5 in all component cables 3 for the picture 2 for audio (if no optical out on DVD)

Let me know that you understand this?
