I would check the scanner slit glass under the toner cartridge. Clean the optics, pull the PCU out and clean the LED erase lamps. After this I would say it was the PCU. I NEVER would mess with the exposure baffles or the focus.

1st the basic cause of dark/grey copies DUST. Clean w/ alcohol cloth then dry cloth totally all mirrors and the platen glass both side. If still dark check the "Optic slit " right in the upper of your halogen lamp remove it, still dark Check your halogen lamp maybe it already oxidized. The last solution adjust the CVR .
I have the AV-27S33 model and in the rear to the right of the inputs are two slits and inside these slits are two screws. The top screw is the focus,the bottom the brightness.Your tv is a different model but it may have this same adjustment,if it does try turning the bottom screw to the right to increase the brightness.
Remove 4 Black Phillips Screws 2 on the front near the handle that flips Use a Good fitting Screwdriver These screws have a thread locker on them. They will strip the heads out if proper care is not used when removing them.Then remove the two screws at the rear of the Iron Just rear of the cooking surface. This will remove the chrome cover on the bottom of the cooking surface exposing the wiring. The thermal fuse is located under a section of insulation under a clamp held in by another Phillips screw.Do not cut or Damage the insulation. Gently pull it back exposing the fuse. After replacing the fuse, insulation ,Clamp and screws check to be sure the iron heats and cycles on and off and the ready light works properly. If it does not cycle the new fuse will blow . Good luck
The type of printer you have reads the image you want to copy by passing the paper in front of a image reader (it is like a wand with a light-slit on a side).
If someone passed in front of this reader a paper with something like dirt on it (or typing corrector not dry enough) some of that could stick ON the light-slit, so that the section covered with it cannot read any more the image you want to copy at that point!
Try to make a copy and look from above or aside where that light-wand is located, then try to clean it with a clean hanky. It could involve some technikal skills, maybe you have to loose some screws to get to it.
If dirt stick on it after this, try with some alcohol (no solvent please!). After cleaning the reader, copies should come out ok, please let me know.
In my case, the adjustment was available from outside the TV. Sortof.
On the rear of the TVabout 2 inches to the right of the coax in, there
are two vertical slits on a little protrusion. Inside the slits are the
two adjustment screws. The lower screw adjusts brightness, the upper
screw adjusts focus.
