The display on my 5 yr old Ft1000MP is gradually going dull. In the "hi" brightness position it is a little more dull than it would normally be in the "Lo" position.. I have established (by substitution) that the inverter unit is OK. The input voltage to the inverter is 9V on "Lo" , and 16V on "Hi". Any help would be much appreciated.
