I am referring to picture noise
yung medyo grainy pag dark scenes. sometimes medyo pixelated din pag dark scene.
Sa people walang noise nor pixelation pero sa background kitang kita
Sir, I spent the whole day yesterday evaluating close to 100 flat panel TVs (plasma, LCD CCFL backlit and LED backlit LCD) from the biggest appliance stores in order to verify your concern since my own AV gears are only SONY, Panasonic, Onkyo and Pioneer ( I don't have Toshiba and Samsung LCD TVs).
You are absolutely correct that the Sammy LCDs are indeed noise free. In fact, the Sammys have the most "grainy-free" picture regardless of the setting.
The plasmas of LG and Panasonic have the worst noise or grainy video (like my SONY CRT TVs).
SONY and LG LCDs (CCFL or LED backlits) are second only to Samsung.
The other brands, depending on the model, are either at par or inferior compared to SONY and LG.
It was really very difficult to evaluate each TV since I was becoming a distraction at the stores, once in a while.
I did all possible tweaking with the Toshiba LCDs (CCFL and LED backlits) particularly on the 32AV700 and we found out that you may do the following adjustment to your 32 -incher to minimize or almost eliminate the noise or grainy video signal ( make sure you have good quality HDMI cable and video signal):
1) turn OFF the NOISE REDUCTION (factory preset is ON)
2) set MPEG NR to HIGH
3) set DNR to HIGH
Observe the screen video quality if the noise is gone or reduced. If noise is still the same, most likely you need replacement or servicing of the unit. If the noise is reduced or at acceptable level then:
4) set MPEG NR and DNR to either LOW or MIDDLE till the noise is still within your taste.
Although the Toshiba TVs are grainy ( like the plasmas and my CRTs), watching them at proper distance made the noise unnoticeable.
Switching to the 32RV700 is futile since these models both have the same level of inherent noise.
