Hi,
I have an esa vt550 HMI which had lines on the screen, so bought a new lcd graphic module, a hitachi lmg7420plfc-x, when i fitted it the screen lights up but it is totally blank. The buttons on the hmi still control the machine though.. why did this happen and how can i fix it?? Any help would be greatly appreciated.. also what software do i need to communicate with it?
