Help request to determine if tuner hardware is faulty Zgemma H7.S

[adm]

Greyed out means they are not available. Post a screenshot on Menu - Information - Devices.

If tuners A and B are no longer visible, this is a hardware fault. Are they soldered on? If not, try resitting into slot.

This youtube video shows the box with the covers off.

The tuners look as if they may be plugged into the mother board.

There is a good chance that tko1 may be lucky and pushing the tuner boards back into their socket will get them working again

thank you! pushed the tuner board back into the slot and bingo,all three tuners are detected again!

wasn't brave enough to open up the box till you posted.

was fairly sure it was not related to the image as issue occurred under one image and persisted after the reflash, but many thanks for the help too @bmitie.
