LCD32880HDF problems

[e3gsr]

Hi everyone
I have been given an alba LCD32880HDF.
I was told it would come on then the picture would go but the sound was ok, When I got it home i tried it and when you first switch it on the picture cam on but the volume slider was decreasing then the picture would go off. After a bit more testing I found if you switch it on by pressing a number button it would say no channels have been added etc etc, But the picture would stay on for as long as you want, If you press the menu button a few times to bring the menu up it would scroll through the menus on its own and i was unable to select any of them except randomly. Now I bought a new board supposedly a working one but when it is fitted the power light flashes constantly unless you unplug the tcon board in which case the screen would light up with the backlights but obviously no picture, The strange thing is this tcon board works with the other board in it.
Probably missed something out so any further info needed please ask but has anyone any ideas what could possibly be wrong.
The boards both have the same number btw 17MB25-3 V1 060309.#any help would be greatfully received.
