    Hi there,

    We’ve recently bought a TH42PW7BX and bought side speakers, JS Tech Scart to VGA V2 unit but all in all the PQ and Lip-Sync issues are disappointing compared to our Panasonic TX 36PD50’s.

    But what I really wanted and was prepared for a slightly lower PQ was a unit to wall mount as the TX 36PD50 is not really wall mountable. Would the PQ and Lip-Sync issues be reduced if we bought a 37” PW7 or are there any other suitable Plasma alternatives?

    Many thanks, Tim.

    how far away do you sit from the screen? and an AV amp can solve any true lip-sync issues. but most lip sync issues originate in the broadcast. I cant help thinking that a TH-42/37PE50 would suit your needs for a wall mountable TV better than a PW7.

    Hi there,

    We can sit between 8' to 15' from the screen. We don't want to use an amp and seperate speakers as we want an all in one unit/solution on a wall. Will look at the smaller 37" plasmas and see if they are more suited to our needs and can match the PQ of the TX 36PD50.

    Thanks for the pointers, Tim.

    In what way do you want the PQ to look like the TX? Black level, contrast, brightness, detail, motion, artefacts...?

    I don't think going smaller will help seen as you've already got a healthy viewing distance (more than 2.5m).

    I'd suggest a demo of a Hitachi - completely different to a Panasonic PW7, and maybe you'll like the much brighter, bolder and hi-res picture. The new 42PD7200 should be even better going on the specs...

    You are using RGB scart right? What do you have connected to the tv? Scart isn't the best thing out there. Don't forget that plasmas only really shine with high quality feeds.

    None of these things will help with lip sync, though maybe you will notice it less with a 37", lips being smaller on them. If you have genuinely poor PQ to the point where you are complaining, you have some other problems. What is the source? Sky, cable or freeview? Given you are connected with a VGA box, there are 2 other weak points, the scart cable and the VGA cable. Both must be up to the job. This does not mean a remortgage, something like a QED squart, and Lindy gols series VGA are usually good enough, that's £50 or so total. Then there's the set top box. If it's NTL then there is your problem. Sky boxes can vary, mostly though they are adequate, a power unplug and restart can help with lip sync, you might have to do it a couple of times a week.

    Hi there,

    Source Sky+ which we have reset several times over the past few days but for us the picture is just not sharp, slightly fuzzy and at times movement seems to leave trails all of which does not appear to happen on our 36PD50's.

    We have also hooked up our E95 direct to the component terminal board and yes the picture is good compared to Sky but again it doesn’t seem quite as good as the CRT’s.

    We're using IXOS XHT 801 scart cables and have tried several VGA cables still no difference that we can see.

    I think we're locked into the Lip-Sync issue which is clouding our judgement and extremely frustrating.

    Will try and demo the Hitachi range over the next few days and will probably sell the 42” and buy a 37” to try, as we would like a wall mounted TV solution.

    Again many thanks for all your help and pointers, Tim.

    Hello Tim-Ann

    The visible differences between the 37" and 42" Display are pretty minimal - the 37" is slightly sharper due to the smaller pixel size but its not night and day.

    A Display does have a different 'look' to a CRT TV - though its usually one that many folk prefer over CRT.

    The differences in video processing time on a 37 or 42 Display will make no difference to any Lip Sync issues your seeing - it may be worth going through the various picture menu settings on your 42" Display and setting everything to OFF; that should tidy up the picture and minimise any delay in the video signal processing.

    Its unusual for Lip sync to be a big problem when your using the Displays on-board sound system - I'd definitely undertake a re-boot of your Digibox; my SKY+ box tends to get out of sync once in a while and pulling the power cord tends to do the trick.

    How does the system look with the Movie channels? - these tend not to be so compressed as the Sports channels and can often look as good as a DVD on a 42 PWD Display.

    Best regards

    Joe

    Hi there,

    Thanks for all that info will try it out later today although as I have said the Sky+ box has been switched off from the mains power several times and still the Lip-Sync issue is there, even when the Sky+ box is just powered up the Lip-Sync can sometimes be seen which leads us to conclude that it is a Sky problem.

    As for watching the Movie channels well unfortunately that is not our main viewing channel it tends to be BBC1 and the News channels which seem more prone to Lip-Sync than most other channels?

    Would I be right in thinking that even the latest Plasma consumer screen's which are designed for TV/DVD with their onboard speaker systems are also plagued with the Lip-Sync problems or is it only the commercial plasma screen’s which have Lip-Sync issues?

    Tim.

    Depending on the source of the lip -sync, if it is sky transmitting badly sync'd stuff there is no solution (drop sky?) 8' is just about as close as you want to be to a 42" but 12'-15' is ideal (15' is 50" distance). I can help thinking something is out on the set up, have you adjusted for overscan? and are you watching material in the correct apsect stretching 4:3 material to 169 can create some of the picture issues you mention.
