Is this how to get into the service menu? I just picked one of these up from TD over the weekend and would love to know how to get into the service menu.
Anyway, came here hoping to find some info on this TV and found this thread. Here are my thoughts on it -- First, i'm hardly a videophile and am not even close to being as knowledgeable as most people on here but I am a gadget enthusiast and have gone through my share of HDTVs starting with a massive Pioneer 65" RPTV, then a 50" Panny DLP, then a Toshiba 44" DLP and finally this TCL 55" LED.
For the price I paid it's a good TV with adequate picture quality. However, regular HD television programming doesn't seem to pop out as much as it did on my 44" Toshiba DLP which was 720P. Basically it seemed a little softer. That said, when I played a blu ray (Avater) on it in full 1080P, the picture was excellent, so I think the slightly lower picture quality I noticed with regular TV was likely due to the source and the fact that it was 720P being upscaled to 1080p on a much larger screen. A true 1080P source looked fantastic.
I also noticed a bit of the clouding effect that's been mentioned, but it was only once on a solid dark screen and is not something that would be a problem during normal viewing, at least not for me. Another thing I noticed was some pixelization or artifacting during a couple of very fast motion scenes during a movie I was streaming from Netflix. The scene was one of those that looks like it's shot with a handheld camera which is very jittery and jumpy and during shots where there was a lot of heavy foliage in the scene with a lot of dark green coloring, there was some noticeable pixelization. But, during fast motion scenes in Avatar in blu ray, I did not notice any of that so again I'm tempted to blame the source material which was Netflix.
Overall, I'd say it's an excellent LED set for a sub $700 price. I can't believe how relatively inexpensive these things have gotten. I paid almost 3K for my old Pioneer 65" and about $1500 for my Toshiba 44" DLP.
BTW, someone earlier asked about the difference between the ZTA, Z, and ZTT models. I had actually called TCL yesterday about that and was told that the only difference is the color on the lower bezel. According to them, the ZTA is all black, the Z has some gray, and the ZTT has some red in it. Functionally and mechanically they are identical.
Now a couple of questions -- regarding the sharpness control, from way back I was under the impression that it should generally be set at 0 on HDTVs because any higher can introduce artificial jagged edges but I noticed someone earlier mentioned the settings they found worked best for them had the sharpness turned up a little. Is it no longer the case on LED TVs that the sharpness is best left at 0?
As for the 240Hz claim, based on the pixelization I noticed in those couple of scenes I mentioned, I have a hard time believing it. I never saw anything like that on my DLP set. Does anyone know if there is any way to actually test the refresh rate?
And if the remote code mentioned above isn't the way to access the service menu, does anyone know how to get into it on these sets?
