How to release the backlight ribbon cable on nikon L810 when replacing the LCD

Just try to view some videos on ifixit dot com. Sorry, but this way I don't need to enter a stupid code when posting this elution.
On ifixit, are lots of videos and manuals about the repair of modern electronics. There must be a flat cable and connection method that looks like the one you have in the camera. I don't think your camera is already online there, but perhaps another Coolpix. Als look to modern phones, because technical stuff looks the same.

I have an old Canon TV zoom lense J10X10REA(DC) 10-100mm 1:2.3 This motorised lens is controlled by a 4 pin plug with 4 wires (red, black, white, green) leading into the internal motor control circuit...

You can test the motor connections using two c batteries in series (3v). Simply connect any two pins with the + and - ends of the batteries. Watch the pins position, which motor and direction of the motor operation. Make a chart of the polarity and the pins used. Go ahead and use it. most of these motors use less than 4 volts to move.

I have dust under outer lens on my 75-300mm f/4 -5.6 III USM

Front element? You can remove this without alignment worries. The lens zoom mechanism tends to **** in the dust.

Have a look at the front element outer ring. There are 3 black screws. Remove these using jewellers screwdriver (y'know, a very small posi-drive one!). Remove this plastic outer ring. Now you can see three small silver screws, that are about the same size - when you try to unscrew them, they just rotate...

This is as they are not screws, but as mentioned elsewhere - they are plugs (if you notice, they are slightly under the casing. Get a small flat bladed screwdriver, and gently prise them out. Now you can just drop the front element into something sensible - like a microfibre cloth (give it a clean whilst you're there.

Get a rocket blower (NOT canned air), and blow away the dust, and you can use the microfibre cloth (or similar) on the small inner front element.

Then replace the outer front element - you will see where it drops into place - there are plastic guide tabs. Push back the silver 'screw' plugs.

Then screw back on the plastic outer ring and you're done - takes 20 minutes at the most.

Error 99

i had the same problem and i found this guide online fixed my problem

1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If it does, then the camera should be
serviced. If it does not, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.
If the message does not appear, please complete the following steps:
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.

Canon EF 75-300mm f/4-5.6 Repair Manual

Mine had the same problem. The electric flexible wire that links to the moving aperture motor in the center is most likely broken, causing the aperture to stop reopen after a shot. this could be proved if you feel something touching inside when zoom. (that is caused by the loose flexible wire, if so do not zoom anymore, you could further damage the wire) It need to be replaced and this requires the complete disassmebly of the lens. I repaired mine myself by adding a thin wire, took me more than 10 hours in total (first tear it apert, pin point the problem, then think of a solution because I did not have the parts for repair, then finally repaired it). If you have never done lens/electronic repair before, don't do that, too many tricks that could lead to further damage.
