    Yes, another PV500 thread.

    I want to put the PV500 problems into context.
    I would like to know if you have seen any of the problems with the PV500 and how much it affects your viewing.

    This thread is NOT for moaning about too many PV500 threads, it is a serious thread for owners/potential buyers to see how widespread the problems are, and to see if they are of any concern.

    I will be showing what results you have posted so ONLY PV500 owners vote please.

    If you can tell me:

    What size screen you have
    Do you notice the contrast change REGULARLY
    Is there a buzzing that is audiable at low volumes
    Do you have the split screen/horizonal line in the centre of the screen


    YOU CAN CHECK MORE THAT ONE BOX

    TO SEE WHO VOTED WHAT, CLICK ON THE NUMBER BY THE RESULTS

    NORMAL VIEWING is when you are just watching the TV/DVD, not when you are specifically looking for the defects eg. Universal logo (contrast change).

    IF YOU CAN ALSO MAKE A COMMENT ONCE YOU HAVE VOTED ,THANKS

    Some other problems threads to read:

    Discovered slight problem with PV500 thread

    I have not noticed any of the problems under normal viewing.

    I can see the contrast change on the Universal logo test, and I have noticed it ONCE under normal viewing, but this hasn't affected my viewing enjoyment.

    I am very satisfied with the performance of this plasma, I would recommend it to anyone thinking about buying one.

    I have 42" and an EH50 DVR.

    Whilst fiddling with cables there was a low volume buzz coming from bottom left hand corner of the rear (through the mesh). It was only really audible with my ear against the mesh. Totally unnoticeable whilst watching, even with volume off.

    I haven't seen the faint horiz. line in normal use, though I have seen it whilst standing a foot from the screen and really looking for it with a lightish, static image onscreen This proves nothing as no-one would do this in normal watching conditions.

    On the contrast changing, surely this is the documented 'feature' called cats (Contrast Auto Tracking System) which kicks in on 'auto' mode.

    No problems with mine at all. Interesting to see what it will be like after run-in period. Piers was complaining on another thread that the PV500s are a bugger to ISF, which is a shame...

    Thanks for your comments, the main reason for this is to find out what percentage of plasma's are affected and the most important question, does ths affect the viewing, to a stage where you would consider returning it.

    I know some people will have a go saying you will defend your purchase, but in my case, I don't give a s**t if I have spent £2K and it is crap, I will be the first to say so.
    That's what these forums are for, honest feedback, especially when a new plasma hits the shops, you won't get this sort of feedback from ANY of the major retailers.
    Most of them don't even know the good bits of the plasma, never mind the bad bits.

    Does he mean that they are hard to calibrate, or do they not need it as much?
    I don't mind if they don't need it much, that is what they should be like when they leave the factory.

    Quote from Piers:

    I've done a quick set-up of a PV500 but haven't done a full ISF job on one yet. The quick set-up resulted in a big improvement compared to the "out of the box" settings, and it then looked good but there may be better to be got from them. Sadly, the PV500 appears to be as anti-calibrator as the Viera's. Difficult access to the menus that enable us to set greyscale, inappropriate default settings that kick in when you do manage to access the service menu and as a result I don't much want to calibrate them.

    Well, I'll still be contacting him after the run-in period, and we'll see if cold hard cash can overcome his rather girly cowardice... :)

    Even if he did calibrate it, the CATS thing would make it a pointless exercise.

    Also I think you may need to define Normal Viewing. A £2.5k HD plasma is not exactly a normal TV and may be open and bought for a number of uses.

    Sorry, mate - I don't see the CATS thing. I really, really don't. CSI, 24, Assault on Precinct 13 - nada. And my 'normal viewing' is watching DVDs and digital TV programs on it – which I expect is what the bulk of forum readers will be doing too. Your point is?

    I've had mine in a week now and so far so good.

    The buzzing is noticeable if I am right next to it and there's no sound but it's certainly not distracting during normal viewing. Not noticed any contrast changes and the PQ so far is excellent - Sky through AV1 is very good indeed.

    The only real pain so far for me is the power on needing a prolonged press on the remote which my Kameleon 6-in-1 doesn't like. Bah.

    From today I can now hear a buzz, so my answer would change :mad:

    I just don't get it - I was swapping the component cables from the Xbox due to the vertical line problem. Turned it back on, and I could hear a very loud buzz. I switched off, put the cables back where they were, and still the buzz.

    I am so annoyed. Now I have to get this stupid 42" TV back in a box, down some stairs, and do the same when the replacement comes.

    This is different from the noise it made before (close to the back).

    This contrast change thing, it sounds similar to what PHD7's do on s-video. There's a stupendous thread on AVSforums about it. Doesn't happen on VGA or DVI, so does not affect scaler users. Wonder if it's the processing being done in s-video even for RGB. I believe some panny CRT's do this too. Anyone with an HDMI DVD player able to say whether it happens on digital signals?

    I have mine connected to the PC via HDMI, the contrast change is noticable on every connection be it HDMI, Scart or YUV.

    I think some sets convert all signals to s-video for processing. If you get colour adjustments for RGB that is how they do it. Not really played much with PV500's, tellys are not really custom install products. PHD's don't do this, so have the prob only on s-video. I use S for picture in picture, not really much of a problem to me therefore. Certainly noticeable if you swap PinP from digital to S.

    I am happy with my screen but in the poll i put that i wasnt as I do notice the contrast change and i dont think that the screen is perfect to view. The choices seemed like you are either happy or unhappy. I had the money to buy the panny but to be honest now that i own both a panny and samsung there really isnt much of a difference. I cant wait till HD starts rolling in as this is when the panisonic is suppose to shine!!

    I have had my 42PV500 since wednesday and I am VERY happy with it so far.

    Can't hear any buzzing coming from the set at all, even with the sound off and my ear up against the set. Have not seen the horizontal line nor the contrast change, but then I have never really looked for them, and if I don't see them withour trying to then thats good enough for me. :smashin:

    Probably next week I will run the DVE disk on it, and if I can afford it then I will get Gordon out to get it ISF'd.

    The buzzing sound was not audible until a bit over 2 weeks after I had the set - so your not out of the woods yet.

    I will have a good look for the problems when it gets dark, but so far 100% happy.

    I would wait till you have had it a week or so before voting.

    I'm using HTPC/DVI -> HDMI 1280x720@60hz Normal, 48% contr, 45%bright, 47% colour)
    all auto setting off (colour mngm, NR, MPEg NR and so on)
    I'm experiencing "dynamic contrast" on DVD playing thru HTPC expecially on some, not all, 2.35:1 movie (like SpiderMan2, look carefully at the beginning of chap 44)
    I've played Spiderman1, finding nemo (full 16:9) and (jumping to sample) and did not noticed the phenomena.
    I've also a sat tuner on HTPC and no evident contrast chang is visible in 4:3 or 16:9 channels.....
    Some little bit "contrast change" while switching among inputs (from DTT on AV4s to HDMI for istance) but imo that's normal, cause they have different video settings.
    More reporting later (i got the set only 1week ago, almost 30h viewing)

    VIREA SERVICE MENU - INCLUDING NEW MODELS

    Here is how it is got into.
    turn to channel 99 on analogue
    bass to max.
    treble to min.

    then press v/- 0n front panel at the slightly after index on remote.

    this is service one.
    press the green button on the remote to cycle through the options untill you can go no further
    then press hold on remote.
    service two should now be showing.

    press the green button and cycle through the options untill you get to the option that says hours used or some thing like that, not sure of exact wording. the value displayed is how many hours it has been on.

    words of advise

    do not change or alter any thing in these menus unless you are absolutly sure of what you are doing.
    You can do some serious damage to your plasma if you are not carefull.

    to get out of the service menu press exit on remote. if that does not work turn the plasma off ten back on again and you should be out of it.
    I take no responsability for any problems caused by entering the service menu

    If you are struggling, check you are on channel 99 on analogue, it may have gone down a channel when you pressed the v/- button.
