Correction: All 5 years warranty by Panasonic.

i just realized that HN never stamp my warranty card when i buy the tv..... is it ok or do i need the HN stamp to make my warranty valid?????

oooo, tq2.... want to ask more thing... i'm using active 3d glass and started to feel dizzy after 30 min... is it normal????? got tips or not to remove the dizziness... hehehhe

Hey bro, what was the reason pana guy chance the board for u? Im not quite satified with my 3d as well, and some distortion on screen when playing hd mkv file, altho it only visible when u look up close like arnd 3ft, Haven try any bluray or dvd yet as i dont have either.

And i encounter restart twice now with in this week.

Get Panasonic to swap a new set for you or upgrade to 65VT50 with a "good negotiated" pricing.   

Might be something to do with the video board that they changed?

While watching the Olympic badminton final now......Dato' Lee....but I still can suggest something in multitasking mode   

Try whether will produce the same problem in the same model with the same BD which Pana guy should be able to arrange it, if the escalation failed, just try to talk to the Technical Manager. 

Then...try to swap your expensive BD Player with a cheaper BD Player (via Pana guy again).

The outcome may give you guys some clues on which part goes wrong. 

Actually when this problem happened, there is nobody in TV room and I just feel strange why suddenly become so quiet.    So, I also not sure what happened.

how do we know our Panasonic plasma tv got problem through looking @ the movie plays.

May be Bro allycat can give you some tips...especially by looking @ the movie plays. 

My current PTV also V20. how long u been using? will try to check wat u have explain.

My current tv is V20 as well, and the real experience you had comparing ST50 and V20 make me think that i should save a little bit more and get GT50 instead.

allycat,

The ST50 out of box is +green in the greyscale and will not be as accurate as ur calibrated V20. I cannot explain why u r seeing motion issues on ur ST50, only after I look at it I can give some insight into it.

The V20 refreshes at 48Hz for a 24p signal, I am unsure what our ST50s refresh at, will confirm when I spend more time on it. However, dynamic false contouring will reduce when u get ur greyscale correct which will need to be done on the ST50 before we can compare.

I calibrated a VT20 yesterday and the black levels had already degraded to 0.007ft/L compared to what the ST50 can achieve (0.004ft/L). The V20/VT20 had better black levels than the VT30 series (and the VT30 had a capped white levels as well - the V20/VT20 does not have that). One thing is that the differences might be between ur older 50in vs the new 65in. The larger sets have a more aggressive ABL that could be something that needs to be managed.

Anyway, once I get the chance to spend more time with a local ST50 I will comment.

On the V20/VT20/VT30, things improved quite a bit after calibration but dynamic false contouring was still an issue. I believe it is much tamed on the sT50 but since u see it, it can only mean that the calibration is off.

Hi. Since you have both the V20 and the ST50, care to tell me is the ST50 as good or better than the V20 in picture quality and very importantly to me, the effectiveness of their respective Anti-Reflective Coating?

Incidentally, can I just ask whether you guys did the plasma break-in procedure before you kena the image retention problem?

I'm contemplating getting the 65 inch ST50 (upgrading from my VT20), was just wondering if the ST panel is still giving the image retention issue if you guys had done the break-in.

Thanks....

Did'nt do the break in before hand (I am still an HDTV amateur...), maybe that's the reason of the IR.  Mind sharing the way to get the break in done? Thanks a lot

Will hv the chance to test one in depth next week (50in) and will report back on the issues u brought up.

Sorry for the delay folks. ANSI contrast on 5X5 checkerboard (on a 50ST50) was 0.004ft/L (black) and 30ft/L (white). APL is definately better than a VT20 I believe. So it will look brighter compared to the same stuff on a calibrated VT20.

I did not see any issues with motion breakup during the 1st scene on Dark Knight especially on the buildings (post calibration). I did see some issues on the later scene where they jump out of the windows (but it was pretty minor and I would need to compare how they are on the Kuro before commenting further). The IMAX scenes do seem to give problems and I believe its the way is encoded. I did not have Lord of the Rings to confirm.

I did not see any excessive posterization on byond especially on the fast moving sports channels or the Olympic channels. Not sure why allycat is seeing what he is seeing. The motion was pretty good with no issues.

However, I did not spend enuf time to confirm as the set was fairly new. TrueCinema greyscale was very red. I had to bring down RedGain a lot to bring it in. I suspect this will bed in as the set puts more hours on it.

Near black was red tinted slightly and I will need to revisit this as I think this will improve after 50hrs or so.

Colour accuracy was the best I hv ever seen (ever) across all saturations.

There is definately more dither compared to the V20/VT20 series. But this also helps in reducing the 50Hz issues that plague those sets.

More in probably 3 weeks on the same set.

Hi Bro allycat,

Suggest you have to spend some time to seriously look for the PQ on 55GT and 65VT while waiting for Panas@nic outcome.

Hardly can't wait right ?

Hardware (Video Card) changing snap-shot at Bro allycat's 65ST50 set.....perhaps he can share with us more detailed findings on the built quality + first impression etc.....

Sorry for the late posting   

Besides VT, Is there 55 inch for this year set say GT or ST ? So far i only saw 50 and 65.
