Unable To detect HDMI equipement on Samsung LA40B550

[abouhejer]

Hi
I cannot understand why my TV is unable to detect HDMI connections. I've tried to connect a satellite tuner, a Bluray Player, a DVD player but
never suceeded. The only HDMI device i could connect was a sony full HD Camescope.
Any body have a clue please??
Thanx for your help

i dont know if upgrading the firmware to the latest from the samsung site may fix it have you messsed with any thing ?

i have the same tv and i can tell you default settings in service menu if you have messed something up ?

Interesting thing......

but it would sound like the main board would be faulty the part to replace is the main board:
BN94-02668C ASSY PCB MAIN

or you could upgrade it to a la40b650 with this part witch gives your tv network capibilities but it would be best to ask here if a user has swapped those parts and if it worked but it shuld:
BN94-02583C ASSY PCB MAIN
