Major crosstalk / ghosting problems with 3d. Philips read this!

[HarleyBarley]

I'm wondering whether to pursue a legal course of action using the Trades Descriptions Act 1968. Under the terms of the Act any descriptions of goods should be accurate and not misleading. If the description is false to a material degree, e.g. has a significant impact on a purchaser’s ability to enjoy and/or use the goods/services then an offence is committed under the Trade Descriptions Act.

Philips advertised the 40PFL9705H "Fully HD 3D Ready for a truly immersive 3D movie experience. Be enthralled by 3D movies in your own living room with the Full HD 3D ready TV. Active 3D uses the latest generation of fast switching displays for real life depth and realism in full 1080 x 1920 HD resolution". This description was certainly a factor in my purchase, and given that in reality the set is pretty much unwatchable in 3D mode then I feel I have been misled.

I thought about this, and even talked to the lawyer. The problem is, they prove You by their service that by their opinion everything is fine. So what You need to do, is to prove them by independent specialist (which You have to pay of course, and pretty a lot, bout 200 euro) that it's not fine. Than You go to court, where even when You win the case, they will change your TV for the same model, maybe for 2011 if You're lucky. And You have very small chances for returning the money you spent for the specialist. And then if the new one still has the problem, everything starts all over.
I'm pretty sure that Philips knows about this, and they are sure that no one wants to lose so much time and money. So I'll be glad when they will change theirs stance about customer service, or they will probably lose every one of them.

The truth is that the 2009/2010 and even 2011 models LCD panel are just not quick enough to prevent the ghosting. There is not any software solution that can adjust this accept one.
I've modified the timings on the glasses but all without success, just because the ghosting is not caused by synchronisation.
It's caused by the lag of the panels, so for example, when you see a lot of ghosting, these are just the LCDs-pixels, which were there for the other eye, which are not able to switch to the color at which they should be.
So if a white pixel for the right eye, suddenly should be black for the left eye, it just cannot switch that fast, so a 'gray' pixel is shown in the left picture and backwards again.

Now for the only software solution that could prevent this is to lower the interval switching between left and right. So lets say that a frame for one eye is shown for 100ms, this should be increased. The pixel with lag is still there but is less noticable because the picture is shown longer and the pixel is able to recover to the good color. Disadvantage is that flicker may occur at one point.

Another hardware solution is to add some heating system behind your screen which causes to heat up the panel which causes the pixes to be faster. I did that and my ghosting is just completly gone with that ! But the software solution should be an option I think.

how can you do these modifications?

It's not there now. Philips should add this feature to their firmware to make the ghosting less, but I think the development department at Philips are not capable of doing such things. I think they only can modify some out-of-the-box parameters. The main firmware is probably created by another company. That also explains why all those bugs and requests are not solved by them.

I've learned a hard lesson last year with my 40pfl9705 that I shouldn't have bought a Philips TV.
Recently I've purchased a samsung 6500 for my bedroom and besides that this TV has the same picture quality as Philips it also is much faster, thinner, has more features, doesn't have strange bugs and has good 3D quality. Also the glasses were half the price of those PTA's.

No, never a Philips for me again.

I have a 46pfl9706t and I think it’s too much ghosting/crosstalk on this. I think this is quite strange since this should be the best 3D TV according to Eisa. I also had a 9705 and the crosstalk on that was really bad. 9706 is better but you can still see it, especially on the sub title when there is a lot of 3D on these. That is probably because they are white.

I’ve now bought another “cheap” 7606 with passive 3D glasses for my other living room, and I must say that the 3D on this is much better. You don’t see any crosstalk at all. How can it be that at cheap 7606 with passive 3D glasses could be so much better than a expensive 9706 best in class 3D TV with active 3D glasses? I’ve tested with the same blue ray player (PS3) and blue ray movie. I’ve also spent hours adjusting my 9706 and I’ve been able to reduce the crosstalk but you still see it to much.

Hi,

try to switch on your 9706 at least 1-2 hours before switching into 3D mode. This should enhance your 3D experience...

if rooms temperature is normal this technique is not enough.
this take place only the summer.

Philips? Never again. So much hard earned money, for nothing. No service, no answers to your questions, no more Firmware-Updates to solve the 3D-Ghosting-Problem. There are so much cheaper TV's with an excellent 3D-Picture, nothing more to say than: Who cares about Ambilight, who cares about best quality of the picture, 3D is the future and Philips doesn't do anything to help it's (ex-)customers.

I have philips 46pfl9706h/12 and also have major crosstalk problems. In some scenes the image goes out of focus...And i paid 2700 euros for this TV because of the good reviews.......Bluray in 2d is nice.But in 3d? CMON philips....fix this with an update please.

For such an expensive TV it would be nice to be able to enjoy 3d.

Im starting thinking that i did wrong not purchasing Samsung D8000.... And 1000 euros less also.....

I also have the PTA 516..no buzzing sound from them..I think they fix that....yayyy they fixed something lol

Yep this has always worked for me on my 58PFL9955. With time to warm up (1-2 hours) and the settings set to Dynamic with contrast etc at maximum, this TV has superb 3D.
