Hi
The F34 means Upper oven cooling fan over-speed or under-speed detected. the corrective action needed in the case is to clean the cooling fan of any debris or dust, if this does not solve the problem replace the cooling fan.
Dim or faint display is a function of the drive voltages to it. A transformer creates these - and the DC voltage is stabilized by capacitors. The capacitors are only rated to 105 C - which means over time the heat will reduce the capacitors capacitance...lowering the drive voltage and diming the display.
Turn off the power - remove the keyboard panel and metal plate it attaches to. Remove the board attached to the metal plate (not the keyboard/board). Replace 3 capacitors (2 x 470 uf 35V, and one 68 uf 35v....highest temp you can get is 125 C.
