The LED's In the display are faulty, The fron besil is so dark that you can not see the funtioning LCD. I initaly placed a new LED across the A and K terminals but it is unabel to provide enough light as the internal ones do. If you could take some of the foil of the edge of the LCD panel you might be able to get enough light in. I am still experimenting, Good luck, but be carfull if you are powering it up with case off
