Samsung 40" lcd screen problem

[netdent]

picked up this 40 inch lcd with screen problems, when first turned on screen is mostly lines and white patches fading etc, once warmed up its picture perfect? however on the left side looking from the front putting presure on the top can make that part of the screen freeze or go completey white as in the whole screen, I realise its to do with the board that runs along the top of the panel, can this be bodged in anyway? as in packing the frame with rubber or whatever?

thanks Ronnie
