Im getting horizental white spots traveling from left to right of my display, what is wrong?

The white spots sound like the Optical Light engine has a bad display, they sometimes start with one or two and multiply.

The engine is about the most expensive part in the set, see attached photo of one

HI unfortunatly they are dark black blotches that no light travels through, they are leakages in the nematic liquid...... you can gently try & massage them away if there still apparent after that then im affrraid Sadly your display is TOAST.

This is a high voltage horizontal output problem. Could just be a loose connection or an intermitant component failure. If you can get into it, check for any loose connections. Sometimes this can also be caused by a large accumulation of dust. Make sure you unplug it before opening it up.

take alook there and see if you can tell what to do.
Then I often find that is good to click on START-control panel once there click on display. There you can control your sisplaay and hopefully get rid of the white spots.
all the best

the scope is stuck,,,its now a right off!

Unthread the machine. Raise the presser foot. Turn the handwheel until the take-up lever is at it's highest position. Set the upper tension dial/knob to 5.
The threading path is as follows:
From the spool around the top guide, down through the right slot, up the left slot, through the eye of the take-up lever from right to left, down through the guide(s), through the needle from front to back.

Red is brakes
brown is clearance lights
yellow is right turn
Green is left turn
White SHOULD BE GROUND but may not be
you will need to test and determine if white or black is ground

The four wires coming from your SUV are clearance right, left and ground

The wiper blades might be the wrong size (too long). Or the arms might have to be removed and repositioned so they line up in the right spot at each end of their travel. If the wipers look like they're flopping about or going at different speeds right from left, then the linkage is broken and you'll need to buy a good used linkage from a wrecker.

In addition, flash lighting dust doesn't make a white spot, but a fuzzy whitish circle (out of focus). The image underneath is still visible, but distorted. These are definitely not flash reflecting on dust.
