Hey guys just a heads up, was watching "The Shadow" on my Samsung lcd last night and the brightness scene to scene kept changing ie going a bit brighter then a bit darker and it wasn't smooth it was noticeable. Just thought it worth mentioning in case some of the issues are inherent in the source and not the tvs fault or they are in the source and the tv is exaggerating them.

Sorry if this is of no use just thought it was worth mention that the brightness fluctuations were happening on my lcd.

Agreed, sometimes the material is to blame. I was watching Sparticus last night and it suffered from some of the worst FBrs you are likely to see. Background kept shifting up and down in brightness. As it turned out it was just a flickering torch that was off screen.

Yes, that does seem somewhat strange, although it does appear to be the case from the reports in this thread. I'm just wondering how true it is though.

Is anyone with pre-installed FW1213 experiencing FBrs?
Are all new sets now being delivered with FW1213?

(I'm still thinking of buying one of these, so have a particular interest in any feedback )

We've had individuals in this thread who've had 2 or more sets. Ones with 1213 pre-installed have not had FBr problems, and their previous sets without 1213 pre-installed did.

Seems fairly black and white to me!

My father in laws 50GT30 suffers from FBr and it came with 1213 pre-installed. His is also a buzzer more-so than my 55VT30

Both 1213 for the gt and 1520 for the vt don't appear to fully cure regardless of whether it was pre installed or user installed. The US fix is entirely different to this.

OK - That's that theory out of the window then

Seems it has resolved it for some people though!?

They probably just haven't noticed it yet. I thought mind was ok after 1520 but the shifts are just lessened and happen a lot quicker. It's still really annoying.

People have tried dedicated clips though!? So far, we've had ONE person say that a pre-installed FW1213 set does not resolved the issue. Everyone else says it has...

What are you watching when it happens though?

Are you sure its not source dependent, Is it actually the tv? As i said my samsung was showing fluctuations while watching "The Shadow" last night and i know it wasn't the tv.

Have you tried the clips that have been provided?

It is content dependant but its also set dependant. A clip may show it on one set and not on another. For me the hereafter clip shows it but since 1520 the apprentice boardroom which is notorious no longer shows it.

So, what you're saying is, a static test shows it, but a non-static test (the footage is different every week?) doesn't show it? Can you see a flaw in the test?

What about my "Home" example? Bet that shows it...

If someone plays the two or three example videos, and don't see FBr then I recon we can happily say FBr has been solved (to some degree).

My own opinion is that for the VT30B range f/w 1.520 really does lessen the number of instances of FBrs when viewing in Cinema, THX and Pro modes. Probably enough so that, after a while, I will stop looking for them!!

FBrs, with the 'right' source material, still do occur very, very often when using Normal or Dynamic modes.

So, f/w 1.520 can not be classified as a 'fix' - definitely not - but it makes life so much more bearable.

No I'm not saying that. What I'm saying is its lessened it to a point where some material that was unwatchable (the apprentice) is now fine. It still shows occasionally but I can't recall what on. Why does it matter what I see it on? I still see it occasionally so its still a problem. If there was a proper UK fix like the US fix it wouldn't show on anything.

From that HDJ link it seems as though there is a proper fix. People are reporting NO fbrs after the 'reflash'/ board swap(?).

I do feel better now!

Saw quite a bit of FBr on Bladder Goes Forth last night so it looks like my GT30 is not entirely free from it, just much less prone than the ST31B was. I will be requiring the eeprom update once its available over here.

I wish Panasonic would hurry up with a fix, watching Dragons den last night was painful, because of the fluctuating brightness )

I've just bought a TX-P46GT30 and I'm really impressed. But then again, I went from a 28" CRT to a 46" Plasma so that's to be expected.

The 1st thing I did was check for FBr's using some scenes from the following the spreadsheet mentioned earlier in the thread. The 2 Blueray's I used to check were Avatar and Casino Royale and I didnt notice anything in either of the scenes mentioned. However, i'm pretty sure I noticed FBr's right at the beginning of Casino Royale when it's black and white. Has anyone else noticed FBr's in that scene?

I have up to 90 days to return the telly if I want, but my 1st impressions are pretty good. I haven't noticed any issues whilst viewing normal TV over Virgin Media. Do FBr's only occur whilst watching Bluray's?

Can someone point me in the direction of a Bluray which really suffers from FBr's quite badly? I wanna see how badly affected my TV is and whether I should consider returning it.

Cheers,

Ham.

Hello mate,
FBrs can happen with any content. Ive tried clips posted on here and not seen any FBr's but the likes of Corrie or Without a trace set them off badly.
If you dont see them try not to look for them mate, its a case of once seen they cant be unseen.

Hi

At what point on Avatar can Fbr's be seen? I will be going to see a 55 inch VT30 on Thursday at TPS.

Thanks

If you haven't seen any then theres no point in returning it. Just keep watching things as normal and if your set is badly affected you will start seeing it. It's content and set dependant plus the same content doesn't show the problem on all sets. The Hereafter clip has shown the problem on the 2 sets I've seen. Mine used to show it on The Apprentice really badly and apparently Dragons Den is bad. I don't see it on either since the 1520 firmware upgrade but I do still see it on Hereafter. Lots of people say The Social Network is really terrible but I barely saw a thing on that even before the firmware upgrade. Scott Pilgrim too but again I didn't see much. So you could try those if you really want to see it but I wouldn't go looking if I was you. I didn't go looking and it just presented itsself to me in my normal viewing so I knew I was affected and started looking at other examples but if I hadn't seen it before I wouldn't have bothered.

why do you want to look for fbr's? two bd films you checked you could not see any so why keep searching for a fault where it may only be very subtle and just end up spoiling your enjoyment of you set.
anfd instead of watching films normally you will be searching for fbr's.

you have 90 days to return your set,so just watch tv normally and within that time you will have noticed whether fbr is a problem to you or not.

with my set sometimes i can go hours/days without seeing any fbr,and other times i get it constantly. e.g was watching chelsea vs west brom on espn hd and not one instance of fbr.few hours later,same channel and i was getting fbr constantly. but i dont get much fbr and when i do it is only subtle which does not make it that much of an issue for me.

sure it should not be there and i rather it not,but i really enjoy the picture from my set 95% of the time and i will not go out of my way to look for fbr when i have better time for my set.

anyway i hope you fully enjoy your new tv and dont encounter too many problems

I've updated to 1.520 by downloading the firmware from the Panasonic UK website. I haven't seen an fbr since....

I have the 50VT30...

The Software Version in System Info shows; 1204-10000

Seems like much older than others on this board. I can't make out the manufacture date.
