HDMI input ceases to work on my TV.

[MrSnake]

My LCD TV is a JVC LT-32S60BU.

Although I've been very satisfied with this TV, I can't get the HDMI connector to work anymore.
One day, it just stopped working.

When I hook up a DVD or BlueRay player via HDMI, the TV recognises the resolution from the player's setup (576p/720p/1080i), but the screen stays black (or green, depending on the player).

The last device connected to it via HMDI was the PlayStation3 (US model), I don't know if there are any known issues with this device?

When I fiddle the HMDI connectors, the screen does not disrupt, so it doesn't seem to be a loose connector...

Any idea or suggestions I can try? (I doubt I still have a warranty on it)

For the record, I had a technician come by and he did something in the Service Menu of the TV which fixed the problem in less than 30 seconds.

If anyone knows how to get into that Service Menu...
