Samsung LE40R88BDX Tuner problem ?

[mzone]

hi guys i have 2 sets in that suffer from exact same problem.

i repaired psu on both model and both tv,s now power up and work ok with good picture through hdmi.

the problem is when you use auto tune to pickup  tv channels it wont find anythink, and im useing a good aerial that works ok on another tv.

also
the dtv freeview is mysteriously absent from the source list and any attempt to use the DTV tuner just gives a "Not Available" message on the screen.

the set doesn't hang or malfunction when the D MENU or DTV buttons are pressed, it just says "Not Available", like it's been disabled somehow.

I've scoured the service menu for any option to enable the DTV function and found nothing.
I've tripple checked all the country specific options. I've even tried the factory reset option several times to no avail.

i have 2 same model sets that suffer from exact  same problem.

Has anyone else encounetered anything similar with this set?

Any help would be appreciated.

thanks
