Assuming the television is OK and you have selected the correct 'SOURCE' then check you aerial connection and retune the set. If this does not work, take the set to a friends house and try in a 'known good' location.there are more information about it

I have a JVC G40 DVD home theater system and when I play DVD's the voice and picture don't match up. Specifically, Peoples lips move and then a second later what they say is heard...how do I fix this?


When viewing on Digital TV:-
Sometimes Audio and Video signal can not be transmitted simultaneously due to additional process time for the video signal compared to that of the audio signal.
Often video signal takes more time than the audio signal to convert from analogue signal to digital signal in the Digital TV.
It may result in mismatch of the picture and sound.
In the TH-G30/40's HD AV Sync menu, you can adjust the audio signal delay for simultaneous AV signal transmission
1. Delay time can be varied in 10msec steps.(0 to 300ms)
2. Delay time is different between TV Brands.
So you need to adjust the delay time for correct lip-sync.
The adjustment is listed in the instruction book page12

Sound but no picture!


This is a normal, input board defective (as switch module inside betwen tv signal and the AV1,2,...) normaly is video chip defective. You need to send tv to repair shop, to check and repair.

Note: Check for tv picture signal, for quality, normally this circuit when defective, changes the quality signal (first some colours level, sync and then totaly defective is a dark picture)

I cannot find vertical hold


The sync is automatic. There are no knobs to turn. If the picture is rolling, look first to the source connection and make sure your tv has a solid vertical sync connection. If you are using the RF input then the issue could be within your small signal board also known as the SSB. Good luck.

Can I record sound only through Camera sound inputs from Record


You might need a source picture from a camera or off the tv so that the DVD has some sync pulses to actually record the sound. Some won't do anything without any pictures.

Sound sync with picture


This may be the broadcast, or the service provider's equipment. We have seen this before. Most people are not too sensitive to lip-sync problems unless they are very severe. With digital TV distributions and the many conversions and signal processes along the way it is possible to have many types of delay problems. On my own TV set which is on a digital cable service I see this on a number of stations.

Green Picture


The problem sounds like one I had. If so, the cause is as follows.

The Daewoo ouputs synchronisation information on the green channel of the RGB outputs (which are pins in the SCART socket) The Panasonic TV automatically preferentially selects the RGB input in the SCART rather than the composite video signal in the SCART. The video circuits in the Panasonic should ignore the sync on the green channel but instead interpret the sync as green signal information which means the adjustment of the green channel is upset leading to a very green picture.

Possible solutions:
1. From the TV, manually select composite video input, not RGB. This may not be possible - I think the TV automatically goes for the RGB if it is present.
2. Disconnect the wire to pin 16 in the SCART socket. This is the signal from the VCR/DVD to indicate that RGB is available. Disconnecting it means the TV defaults to the composite video. This is what I did.
3. Connect the TV to the VCR/DVD using component or S-VHS leads only.

HD compatibility - Not


You need to nail down where the problem is by finding another source of 1080i signal and prove if it is the TV or not, then hold Proton's feet to the fire if it is.

If the sound on your DLP TV is out of sync with your picture and the TV is not connected to a home theater system, a Samsung technician can adjust the sound sync function on the TV so that the sound and picture are in sync.
To arrange a service call to adjust the sound sync function, call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864).
