The display unit on my eko 2000 inverter is fogged up. Can I simply undo the screws on the face of the inverter to clean?

what system have you got?????

REMOVE AND REPLACE SPEEDO FACE
How to remove the speedo face
Undo the 4 screws that hold the black cover in front of the speedo. Pull the cover off. Undo the 4 screws that hold the instrument cluster. Lift out the cluster. Disconnect the 2 or 3 mulit-plugs from the back. Remove the black panel that hold the glass (push clips). If you don't have the proper tool, use 2 metal spoons to lift the needle from the speedo face. You use the bowl of the spoons on the needle and press on the handles. (It's easier than it sounds.) Undo the 2 screws that hold the speedo face on. Lift it off. Fit the new face.
How to zero the needle on a new speedo face
Fit the speedo unit (without the glass) back into the dash, with all wires connected into the back of it.
Don't fit the needle-stop post to the speedo face yet.
Switch the ignition on. Fit the needle in the zero position.
Now fit the stop-post and glass.

The EKO 5000DB inverter is purportedly a rebranded 5KW Solis Ginlong inverter. Here is a YouTube regarding steps to take if an OV bus error message is encountered.

Several things can cause your Dell Latittude D600 laptop's LCD screen to stop working.

Two of the most common causes relate directly to the inverter board and the backlight lamp.

The inverter board is a thin circuit board placed inside the LCD panel.

It's main function is to transfer power from the motherboard to the backlight bulb inside the LCD screen.

If the inverter board goes bad or the backlight lamp burns out, the screen will appear dim or eventually go completely black.

Turn off the laptop, unplug the power cable, close the LCD panel and place the laptop face down.

Remove the battery pack from its compartment on the bottom of the computer.

Flip the laptop back over and reopen the display panel all the way until it is in a 180-degree position.

Insert a flat head screwdriver into the right side of the keyboard bezel.

This is the plastic strip situated above the top row of keyboard keys. Carefully pry the bezel from the laptop.

Remove the two Phillips screws located above the top row of keyboard keys.

Grasp the top edge of the keyboard, tilt it upward and lay the keyboard face down on the palm rest area.

Unplug the keyboard's ribbon cable from the motherboard connector.

Carefully remove the entire keyboard from the laptop.

Disconnect the video and speaker cables extending from either side of the LCD panel to the motherboard.

Loosen the Phillips head screws on each LCD panel hinge.

Carefully lift the entire LCD panel off the laptop's base.

Relocate the panel to a flat work surface, and place the panel so the screen is facing upward.

Use a thin, flat head screwdriver to pry the rubber screw covers from the LCD panel's front plastic cover.

Remove the Phillips head screws revealed by the rubber covers.

Carefully remove the front plastic cover from the display panel.

Locate the inverter board situated below the LCD screen, inside the bottom edge of the display panel.

Disconnect the two cables from each end of the inverter.

Remove the two Phillips head screws fastening the inverter to the display panel.

Carefully lift the inverter board out of the display panel, and dispose of it.

Repeat this procedure in reverse to install the new inverter board, and reassemble the laptop.

Hope this helps

1. Turn off the computer and remove the battery.
2. Loosen the plastic frame bordering the Toshiba Satellite L555D-S7005 Screen. This frame is attached to the notebook's back shell and holds the screen in place. Pry open two to six small rubber seals from the frame and undo concealed screws.
3. Detach the frame after removing all screws. Hold the bezel from either side of the screen and gently pull it away from the screen and toward you. If the bezel seems to be stuck, find any points of attachment, such as clips or hooks, and undo to detach it from the outer shell. Work with your fingers and go all around the frame to release and completely detach it.
4. Free the LCD panel from its position in the notebook's lid. When you remove the bezel, you will notice that the screen is held in place, enclosed in hinges. Undo screws from either side of the screen to release its attachment to the lid. Place a finger at the top center of the screen to keep it from falling down as you remove the screws. With all screws undone, tilt the panel and lower it face down onto the keyboard.
5. Disconnect the power cable and video cable from the screen. The power cable connects the screen's power source of the lcd inverter to the backlight lamp attached to a side of the panel. Unplug cables from either end of the inverter board and unscrew the board from the base of the screen. Next, find and unplug the video cable a broad, ribbon like arrangement taped to the back of the panel. Pull at the plastic head of the cable to detach it.
6. Remove the screen. With the screen's cables unplugged and inverter board removed, it is completely detached from the notebook's display assembly and may be safely removed. Pick up the panel from the keyboard and keep it to a side.
7. Orient the replacement screen by bringing it to the work area and aligning it to the laptop's shell. Gently rest the screen on the keyboard and attach the power cable and the video cable. Raise the screen and attach the inverter board to its base. Plug in the inverter board's cable to the screen's backlight lamp. Screw the screen in place and reorganize the display assembly.

I think they should clear by themselves, they are not sealed and can bee removed after only taking the very top (black Plastic) off the unit. You have to have fairly nimble hands but it can be done. The Dials come out with a quarter twist.

The inverter is located behind the bezel at the bottom of the screen/lid and in between the hinges.
The bezel has screws that fixes it to the lid and these can be hidden by stick-on plastic covers. Use a thin sharp point to lift these plastic covers off to reveal the screws. Remove these screws.
The bezel has small plastic catches that clips it to the lid and may also be fixed to the LCD screen with double sided tape. Use a thin blade and insert it between the LCD screen and the bezel and gently ease the bezel off. Start at the bottom of the screen and gradually work along the edge and continue around each side to free the bezel.
Be CAREFUL not to scratch the LCD screen and DO NOT apply too much pressure to the face of the LCD screen because you can crack the glass surface and ruin the LCD screen.
Once the bezel is removed then you can get access to the inverter to remove it.

ring around clear number section pulls off then there are three small flat head screws undo those aand the outer face with the dial comes off. if you are just trying to clean out the clear dial from bugs or small debris simply lift with small screwdriver and blow into it.

Had the same issue, and used the solution for cleaning the underside glass to get the button and display assembly off - http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c00553775&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN

Once you have the scanner lid and button face plate off, put a med. size screw driver in the sqaure hole of the assembly and carefully push down while prying it slighty forward (towards the front). Carefully undo the wires from the molded hold downs on the main case to provide working room. There is metal clip that allows the LCD display to move up and back. It's likely been bent the wrong way and simply needs to be realigned.
