make sure the movie got DTS audio format. check audio menu, find digital out option , make sure set to DTS.
the LCD support DTS, DD and PCM stereo digital out.

anyway.. my LCD now got stuck pixel.. damn.. green colour..

yep.. stuck green colour pixel..
the panel have been changed bcoz last month got 1 vertical line of DEAD pixels.
last week 1 STUCK green pixel appears..
the LCD is just 6 month now..
will call samsung next week.. hope they cover stuck pixel also..

i think maybe ur movie come with DD.
i tried mine (D550) it does have DTS option if movie come with DTS audio.

have u tried other movie?
urs is C or D series?

ic.. might be C series doesnt support DTS.?

u mean playback from usb?
pause n resume?

oo.. i think this feature doesnt have..
if exit the movie no resume available..

usually no major firmware update in the latest firmware..
i read somewhere.. no point to upgrade.. unless there is major update..

yep. sound mode cannot changed..
that is 1 of disadvantage of this LCD. no line out..

using headphone out to speakers the sound not punch/oouummpp enough..

i think there must be line out inside the PCB somewhere..
waiting for samsung to come for warranty.. (i think must changed panel again..).. then i might sneak to see the pcb.. hehe

MP4 not fully supported i think.. i always avoid dload mp4 format.

i think D series better.
newer.. more codec supported i think.

yey.. yesterday samsung changed again my LCD panel..
hopefully no other issue..

LA40D551

installed samsung remote for android on my SGW last night..
now can control my LCD with SGW.. nice samsung features..

ok now.. i also accidentally messed up my lcd calibration..

under service menu > adc > adc target > AV/COMP/HDMI calibration (somewhere in the ADC menu..)
in calibration pressing left doesn't go back to menu but, running the calibration..
so, i 'accidentally' calibrate the HDMI source..

the LCD still workable, but i think some values have been changed..

i need somebody to capture/note down the values in the ADC service menu..







if anybody care enough to post up the default values..


other method to recalibrate is to use 8x8 checkered black white board display thru HDMI in.. but currently i do not have any HDMI capable media to attach to my LCD..

manzaro, u can copy mine.. but i think its a bit way off from factory default.. but still good enough to watch..

Added on December 26, 2011, 4:44 amsome searching.. found this..

this is for UN40B6000VM LCD (i think samsung LED 40 inchers)
http://www.turuta.md/SMODE/UN40B6000VM.pdf
page 4-5.

not sure if the values is same with ours (LA40D550/551)
might worth to try or someone can look up their untouched values to compare..

thanx for the values.. i will try later at my LCD.

so using laptop with hdmi to ur LCD to calibrate?

anyway, does HDMI calibration also effect other input as well?
as i watch using terrestrial (RF antenna) analog channels, the pic quality also seems affected.

have u tried other sources to see if its happen again..
AV, hdmi, pc, etc..
