Re: samsung ps42c430

The X-main is faulty -- it's a common issue with this model. After you replace it, it's essential to update the software on your TV to prevent the issue reoccurring.

Re: samsung ps42c430

IIRC, the board is available for under £20, so I'd just replace it as it's not easy to repair them (lots of hard to source parts.)
Since you unplugged X-main and the sound came back that's more than likely where the fault is.
