Hello, although I'm new here with posting, I'm not new with reading this forum. And I just want to make a contribution to this forum. 1st of all, thanks for all the information and tips and tricks. I find it really useful, handy and sometimes very entertaining.
When I start looking for a LCD TV I soon ended up with three Europe models (after visiting shop after shop
1) Sony KDL 40W2000 (40V2500 elsewhere in the world)
2) Sony KDL 40X2000 (40XBR2)
3) Sharp LC 37XD1E (LC37D90U)
4) Sharp LC 42XD1E (LC42D62U)
5) Philips 37PF9731D (same everywhere I think)
So, I'm not different in this then most of the people that are looking for a LCD TV, they most of the time end up with the same types or brands. Then for me the game starts, what is known about these TV's on Internet
. For my input I used the following Forums:
AVSForum for Sony and Sharp
AVForums for Philips
gathering tweakers net for Philips as well (Dutch site)
I had some time, so I read al the forums from a to z. like I said, I had some time. Actually this is more fun then buying the thing :-). And I can tell you, there is no technical perfect LCD set in the world, every LCD tv has something wrong (noticeable or not), so you are not alone in this. I just wrote this message because in all the forums I noted that more people were doubting between these brands, but nowhere was a common forum about these sets to compare all the bugs. I will try to do this and will post this message in all forums I just mentioned. And remember not all panels have these problems, a lot of people have panels without the bugs (or at least they don't notice it, so you can always be lucky. Also see end of this post).
Sony panels have:
- clouds (mura effect). also called uneven back light
- flashlights, bright light spots most of the time in the corners of the screen. I think that this is the same as back light bleeding.
Sony is not really admitting that there is something wrong with the sets. although there is a firmware patch. this is not really solving the problems, but masquerading it. people think it has to do with stress on the panel, there is a kind of fix for (called the VIPER fix) and also rubbing the screen with a clean paint roller or cloth can work (ya, you read it correct
). Some had success with one or both of the technique, and some not. For now it looks like that Sony found the real problem, and that the February build TV's have a lot less clouds and bleeds, but this is still in investigation on the forum.
What I understand is that Sharp has one big problem in all their panels:
- Banding, lighter or darker bands over the screen. Real visible when you put up a grey input screen on the set.
- Some also have a kind of cloud on the screen, at the mid-bottom, or backlight bleeding.
What I understand is that Sharp is aware of this problem and offers sometimes repair or exchange of the set, but Sharp is responding to individuals and is not going to recall all sets.
So you just have to keep calling Sharp, or changing your set until you have one with less or no banding, so it will not be visible during normal operations and hope that it will stay that way during the lifespan of this TV.
**Please note that the 42" model is not manufactured by Sharp at its new Kameyana II plant and doesn't share the 2,000:1 contrast ration as its 46" and 52" brothers have (the 42"'s contrast ratio is listed as 1,200:1). This doesn't mean the 42" is a bad or terrible 1080p LCD, but it's also not as 'tricked out' as its 46" and 52" counterparts. Also the 46" and 52" has banding problems.
Also here some problem:
- Banding, the same as with the Sharp. And that is not a surprise because the Philips is using Sharp panels in this line of TV's.
- Ambilight sometimes not working correct and some back light bleeding, but less reports about this one.
Philips admits that there is something wrong with the screens and from this moment on, they start exchanging all the defect panels with new ones. This is also on an individual base. Results are not known yet because this process just started. Also some panels they only exchange the ambilight module, so the cause of the problem is also different for some of the LCD tv's (maybe because in the beginning they used the LG/Philips panels). There is also a new firmware versions that seems to solve the ambilight problems they users had in 1080i mode. Looks all promising for the Philips users. And the customers in the Netherlands get an extra year of warranty when the panel is changed. Don't know about the other countries.
Well, for me the choice is still very difficult. What I understand from reading all the forums is that choosing for one of these brands is really personal. Sony users find their TV to have the best PQ, and the same counts for Sharp users or Philips users. So, this is really personal. Go, and look for your selves to make a good choice, no one can help you in that.
For me, the Sony and Philips have the best PQ, and I still cant choose which one to buy. Maybe wait for the new 120Hz tv's, but these will also have bugs I'm afraid, new technology means new bugs right?
Hope this helps some of you in their choice. Before I end this post, be aware of the AVS Layer!! This is about the fear for buying a LCD after reading these forums (found this in the Sharp forum):What about the AVS layer? Is it applied to these LCDs? Does it affect banding/clouds/bleeding?
Originally posted by lorenzow:
The AVS layer is actually applied after manufacturing. It is a virtual layer that sits between the TV and the back of the chair. It comes into effect after visiting the AV Science forum. It causes visual distortion and hallucinations followed by extreme anxiety, obsessive compulsive behavior (endless peering at grey screens), paranoia and feelings of persecution. It is sometimes resolved by returning the TV but often leads to Post Traumatic Stress Disorder which causes the sufferer to return to AVS long after return of the TV to demand retribution from Sharp and insisting that everyone must install the AVS layer.
In other words, yes, every brand out there has some issues with their panels, but that doesn't mean that the panel you want to buy or already have is affected or that it is bothering you. Don't keep on looking with a magnifying glass to see if your set has a known "bug", because if you do, you will find what you're looking for, if you look/test long enough. Make the call for your self, is it bothering you yes or no? And make sure that the shop has a return policy, you may need it.
