Emax

see told you ted was the man if he fitted an led light version it would just 
burn out the led so in effect would need a new led back light

if he is going to fit an led back light he neads to remove the inverter and 
link the 5v across to get 5v to the al terminals also need to add a current 
limiting resistor or the led back light will burn to brightly and burn out 
quickly

the correct  resistor should be given with the manufacturers guide lines if 
fitting an led version  you will have an extra 7mm in hieght from old lcd so 
you need to take out the glass cover and file so that the new lcd will sit 
through the front panel

then you can buy a lcd cover glass which can be glued to the front metal 
plate thats what i had to do to mine

ted do you still have that spare front lcd and buttons pcb as i know i 
wanted it but had a new child and funds became a little short but am do some 
extra fixing so will be into some funds
