whiteknightoz Posted June 29, 2007 Share Posted June 29, 2007 am over the moon with my new 50" 70A but have e problem with the sound that is starting to get annoying. It only ever happens in an add or while watching a Divx movie. the sound sort of breaks up and sounds distrorted, it allways happens on channel 10 when they have the channel 10 add on advertising whats coming on next etc. any ideas? i thought that becuase its a Digital signal it was either received or not ie there was no sort of "bad" signal possible?

Ok I'm not the only one then, no probs with divx as that goes straight into the AVR, the tv sound also goes into the AVR but I also have the sound problem, mostly on channel 12 (10hd) and mostly in the ads, and sometimes on 70 (7hd). I have the 42" 70A Cheers Karen Link to comment Share on other sites More sharing options...
diesel Posted June 29, 2007 Share Posted June 29, 2007 Sounds like you guys have an issue (no pun intended ). I have the older 600 series and no such problem. I'd be giving Panasonic support a call Link to comment Share on other sites More sharing options...

I'd be giving Panasonic support a call Will have to do that next week I thought it might just be a reception prob although I don't have the problem with the Humax HD STB I use on the PA60A. Seeing as whiteknightoz is having the same prob in Brissie as I am having in Melb it may be a prob with the tv, I actually read somewhere yesterday that Panasonic were recalling the 70A due to tuner porbs (not sure how accurate that is though).

Guest Hybrid Posted June 29, 2007 Share Posted June 29, 2007 I've had my 50PX70A since Tuesday and come to think of it a few times I have noticed the sound crackles for a split second. This has happened maybe two or three times. I will pay closer attention now to see if it only occurs on one channel. How long is this problem lasting when it occurs? Another thing I have noticed is the brightness of the screen changes by itself from time to time. I will be watching a program and it will suddenly go noticeably darker or brighter by itself. Not sure if this is some power saving feature or something - I haven't read the book from cover to cover yet... I have noticed this problem at least five times in 4 days.

Had my 50PX70A for about a month now and no problems here. Only sound and picture problems I have is with bad digital reception from time to time, but no other sound problems on FTA, divx or DVD.

whiteknightoz Posted June 29, 2007 Author Share Posted June 29, 2007 Yeah by channel 10 I meant 12 (10HD) It is guaranteed to happen in the adds most of the time but I have never noticed it during any programs. I thought it may have been reception but its strange how it only ever happens during commercials and mainly if there is a voice over and music in the background. I will give Panasonic a call next week i think now that I am not the only one.. Link to comment Share on other sites More sharing options...

Guest Hybrid Posted July 2, 2007 Share Posted July 2, 2007 I now believe that my sound issue relates solely to the broadcast and nothing to do with the TV. I think I was being a little paranoid when I first posted. With the change in brightness I believe that this behaviour that I have witnessed is normal. I have only ever experienced this symptom when the "Power Save" setting in the menu is enabled. I do not think there is anything wrong with my new 50PX70A Link to comment Share on other sites More sharing options...
aaronw Posted July 13, 2007 Share Posted July 13, 2007 i have a 50PX70A and i am having the same sound issues as described by a few of you. Hybrid, how have you determined that this is purely a broadcast issue? have you resolved your sound problem? if so how? firmware upgrade? different tuner? I am really frustrated with this sound issue and would be very appreciative of any help. Thanks Link to comment Share on other sites More sharing options...
Existenz Posted July 13, 2007 Share Posted July 13, 2007 I noticed that exact same thing too when I watched Law and Order on Thursday night (Ch12 - 10HD). Link to comment Share on other sites More sharing options...
Guest Matt_77 Posted July 13, 2007 Share Posted July 13, 2007 I have the 42PX70A no problems with brightness shifts although I have had a few instances of the sound just going plain wacky. Only lasts a few seconds and has only happened twice, it was on a ten digital add so I put it down to reception/general reception issue. Link to comment Share on other sites More sharing options...
diesel Posted July 13, 2007 Share Posted July 13, 2007 Most issues I have had with FTA has been with 10HD in Sydney. I have put these down to reception than anything else Link to comment Share on other sites More sharing options...
whiteknightoz Posted July 14, 2007 Author Share Posted July 14, 2007 Wonky sound on mine started out now and again but now happens all the time especially on TEN HD add advertising channel 10. Spoke to the place of purchase they said to go straight to Panasonic. Friend also has the same set and the same problems.. I dont think its reception as I have a STB on an LCD in the bedroom and never get sound problems and they are utilising same antennae. Link to comment Share on other sites More sharing options...

I am really frustrated with this sound issue and would be very appreciative of any help. Thanks My sound issues only last for a split second. I think I had the same sound issues with my SD PVR on my old CRT - pre Plasma. I really don't notice any other abnormal sound issues with my 50PX70A.

aaronw Posted July 16, 2007 Share Posted July 16, 2007 i called panasonic and they just gave me a contact for a local appliance store who deal with Panasonic stuff. the guy at the appliance store said to check if my analog ch10 is snowy .. if so it could be reception or interference. But its not its perfect. i have tried heaps of test but its hard to narrow it down cause there are so many variables. See the thing is my mates tv from the same outlets did not have these issues ..so I doubt its reception. Im borrowing another friends hd set top box tonight to do a few more tests. Such a pain cause its not like you can just easliy pick it and take it to a shop to have it looked at. Link to comment Share on other sites More sharing options...
crashbaby Posted July 16, 2007 Share Posted July 16, 2007 I have a bigger problem. 2 minutes after turing on my brand new TH-50PX70A about a third of the screen went a strange colour(was on a menu screen) and when switching back to tv stations vertical coloured lines appeared in the same area. Tried turning off the set. No joy. This continued for an hour and a half on all screen inputs as well as menu screens. Then it disappeared. Has been fine since saturday night. Has anyone else experienced this. Very unsettling on $3000 tv! Link to comment Share on other sites More sharing options...
danej Posted July 16, 2007 Share Posted July 16, 2007 I have the same sound issue when watching Ten HD on my 42" 70A - it seems to only appear on network promos and some credits. Link to comment Share on other sites More sharing options...
whiteknightoz Posted July 25, 2007 Author Share Posted July 25, 2007 I have the same sound issue when watching Ten HD on my 42" 70A - it seems to only appear on network promos and some credits. absolutely !! exactly the same as my problem. My dilema is how to demonstrate it to a tv repair guy as it only happens on some adds, and allways during the simpsons credits. Link to comment Share on other sites More sharing options...
Polymer Posted July 30, 2007 Share Posted July 30, 2007 Add one more to having seen this. Only on Ten HD and only during an advertisement (It was the date rape one). Nothing else seems to be effected by this... Link to comment Share on other sites More sharing options...
