The LCD display on my Hotpoint WT960P is broken. How can I mend it?

The LCD panel on my Hotpoint WT960P is broken. The machine itself works fine, but because the LCD doesn't light up properly we can't use all the cycles. Is it cost efficient to mend it and if so does anyone know where I can get the part and how I can do it PLEASE? I've checked Hotpoint's website for spares and they don't seem to stock this particular part.
