Samsung service mode code?

[mania]

Hi does anyone know the code to get into service mode on Samsung flat-screen TV's?

I hook my laptop to the TV via a VGA cable & audio cable but the TV does not see it.

In the source section of the standard menu only AV is lit.

PC, HDMI etc are all greyed out.

I read somewhere that this may be remedied from the service menu.

I actually got in once but cannot get back in & was not done browsing.

I believe I used power off, mute,1-8-2 but this does not seem to work now & I cannot find anything online.

It is a smaller Samsung model # LA19R71BX

Thanks for any info

EDIT: Found it & with TV off it is Info, menu,mute, power

But no setting in there to enable PC

turn TV off. Hit mute 1 8 2 power.
