Color bars on both sides of picture

There are usually 4 side by side green bars if the battery is fully charged. You can think of each bar as 25% power, so (4) bars is 100%, (3) bars is 75%, (2) bars is 50% and (1) bar is 25%.

As long as you have a good signal going to the set, absolutely return the set, especially if it does the same thing when hooked up to another source like VCR or DVD.

a freezing picture is normaly due to bad input signal have your imp input signal checked

you need to change the color wheel

Samsung's digital light projection (DLP) televisions use a spinning color wheel to create the colors that are seen on the screen. If the color wheel becomes misaligned during use, it will become damaged and have to be replaced. Replacing the color wheel on a Samsung DLP television can be done at home, once a compatible-sized color wheel has been bought from a TV supply store.Replacing the color wheel yourself will void any Samsung warranty that might be in place, but is the only solution for getting the TV working again in as short a time as possible.
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the Samsung DLP TV. Turn the Samsung around so that the back is facing you. Make sure the Samsung is unplugged from the AC socket.

Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
3
Loosen the two screws from each side of the projection bulb's case. Pull the projection bulb out. Put the projection bulb aside. Use the Phillips screwdriver to remove the two screws from the left side panel. Pull the side panel and the circuit board attached to it out carefully and put it down so that the cables attached to it have not been pulled out.
4
Take a picture of the power cable's position with the digital camera so that you can put it back correctly later. Pull the power cable out from inside of the Samsung's case so that the center panel is free to be pulled out. Remove the two large headed screws from the center panel with the Phillips screwdriver. Remove the top two screws holding the panel to the plastic case using the Phillips screwdriver.
5
Slowly slide the center unit out a few inches. Take a picture of the projector lens' positioning with the digital camera so that you can put it back correctly later. Unplug the two cables from the left side of the center panel. Unscrew the sensor switch using the Phillips screwdriver. Slide the center panel completely out of the Samsung and put it down on the clean cloth. Blow off the color wheel assembly with the compressed air.
6
Use the tweezers to remove the green plug from the top of the color wheel cover. Use the tweezers to remove the two cables at the side that are coming from the color wheel. Use the Phillips jeweler's screwdriver to remove the screws from the top, front and back of the color wheel cover. Slide the color wheel cover straight up to expose the color wheel.
7
Use the Phillips screwdriver to remove the three screws holding the color wheel to the color wheel assembly. Lift the color wheel up and out of the color wheel assembly and discard it.
8
Position the replacement color wheel in the color wheel assembly. Reassemble the color wheel and reassemble the color wheel assembly. Put the color wheel assembly back into position in the rear of the Samsung DLP TV. Reassemble the Samsung DLP TV. Plug the Samsung DLP TV back in for power. Turn the Samsung on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.

I have exactly the same problem and a Dell tech just recommended I replace the drum cartridge - $170.

The screen does not work properly .Ribbon wire fails.

Your blend door actuator (also called air temperature actuator) motor is bad. It's pretty common. The bad part is located under the dash on the driver's side, toward the center of the dash It is mounted on some AC ducting, with the top of the unit facing toward the driver's door.
Here's a forum thread discussing this issue (not monte carlo specific, but the pics of the part and the general location of said part is nearly identical. They take out a passenger side actuator motor in the thread. Driver's side is similar):

For a temporary fix if you're slightly inclined to working on cars, get under the dash and remove the plastic covers hiding the wiring in the driver's foot well (a couple push tabs and a couple phillips screws is all that holds it up). Locate the driver's side actuator motor (it's partially hidden by some wiring, you'll have to reach up there toward the center of the dash to find it), remove the unit (2 gold colored phillips screws and a black connector, a #2 phillips bit in a quarter inch socket applied to a small quarter inch drive ratchet works well here), and then manually flip the blend door to the "cold" side (there will be a little knob sticking out of the AC ducting that you'll see once you take off the actuator motor. Just grab that knob as gently twist left or right to make the air temp hot/cold).

Here is a cheap place to get a replacement:

GM wants $100 for the same part, not including the labor to install it (probably $45 to $90 for labor)

Good luck.

I have a 50 inch phillips plasma and the pixtals are taking over and color is dark the amblight is very dim,
