Tuner A: (empty) nothing. Tuner works in another DM800 but not found on setup. HELP!

[JaySTROKE]

First time I have posted and still learning the ropes.

Just bought 2 DM800 HD's

I have 1 working fine (even after bricking them both, CA Error!)

The 2nd will not display the Tuner, during setup.

When I go to Service Searching > Tuner Configuration > Choose Tuner > Tuner A: (Empty) > nothing

Now I know the tuner itself is fine as I put it in the 2nd box and it works. I have also tried several variations of BL72 and Images to no avail.

Does anyone know if this is a Software or Hardware issue?

Would appreciate any help you can provide.

It's driving me crazy! and I am reluctant to send it back to China.

Cheers
