of coz C lar

contrast is 100/100 and backlight is 10/10

OMG....not too bright meh? Try to reduce 50% and c if ur heat problem go away.

I think he meant, backlight = 10/100.

that backlight settings is just ok for my eyes only, if i use 5/10 is too dark, but will try and see it tomorrow

no....

backlight is 10/10

contrast is 100/100

More backlight will increase power consumption also

Your backlight and contrast also at highest setting..no wonder la..
Somemore your TV model has very high dynamic contrast ratio..

I think for house viewing, Contrast @ 75, Brightness @ 45 and backlight @ 8 is more than enough..

i set backlight to 6/10, the temperature really went down, by A LOT!!

but 6/10 backlight too dim for me

You might want to find optimal setting for your particular model. Search the net.

i mostly set the settings to my standard, if just follow the choice from my parents, what they see also the same

there should be only heat and not hot till you can't touch the panel..either LCD or Plasma (generall produce more heat)

If too hot am sure something is not right....later panel might melt also

of course can touch the panel, if cant then really serious problem
