F3 Problem?

[CGW]

Know the drill well. Also painfully aware how non-authorized techs do "wall jobs" just like their automotive bretheren. Saw the part, saw the part # and schematic and the bulletin--no dice. Money wasn't a huge consideration since $200 buys high-rollage beaters with issues. My F3's still working--no complaints for a camera pushing 30 I've used steadily for 8 years.

Something else that can cause LCD "fade" is dirty mirrors. Mine was getting dim and I decided to investigate. Without the prism it looked fine, so I figured it was inside the prism. A film had built up on the little mirrors inside and especially on the long one behind the faceplate which reflects into the prism. A careful cleaning and all is well.
