The LCD has ceased functioning - a complete blank screen. Does anyone have any suggestion; is there an easy way to rectify this problem? The unit is functioning well without the LCD.

That is a common problem with those head units, I sent mine in for repair a lil while ago & it cost me £60.00 ........ Less than a year down the line my crystal is missing segments again ........ I'm just going to bin the thing & buy a aftermarket one .......... Its a shame cos the unit sounds great....... Just totally unreliable :(
