Intro
First of all, I'd never buy a DLP TV if you don't want to learn how to take care of it! They can be a pain in the behind if you don't treat them nicely. They have lots of touchy components including a lamp, a color wheel, etc. However, they're cheaper than LCD and Plasma screens and have a great viewing angle (you can sit off center and still view comfortably). Look for a good contrast ratio, too, as this will make the colors more vivid!
Do's and Don'ts
Be gentle with the TV. This is a general rule for all televisions, but with this one, you don't want to jar the lamp! Or worse, what if you broke it? They're not cheap to replace and should last if you just treat them nicely. It's also important to note that the lamp gets very hot and will have a reduced lifetime if not allowed to cool between uses.
You'll also want to give your set breathing room and keep it clean! Invest in the few bucks for a can of air and blow it out every so often. This, combined with giving the TV its space, will help avoid overheating.
Symptoms and repairs
My TV turns on for a few seconds before going black! I can still hear people talking, and Tom Bergeron making terrible jokes about video clips, though. What's up?
In this case, it's often a bad lamp. You may have noticed over time that the picture got dimmer and dimmer or that it has been taking longer for the lamp to "warm up" and display the picture. Many TV's will have a power light that turns red and blinks or stays lit. Different patterns mean different things diagnostically. However, a red LED paired with the above mentioned symptoms is generally a good indication of a bad lamp! You can do this repair yourself. Look in the user manual if you still have it. Normally, you have to remove a door near the rear of the television and remove a few set screws to get the lamp out. The new lamp should NOT be touched with your fingers. Use an old t-shirt or gloves to handle it. Be sure to let the TV to cool down before removing the old lamp. You can easily burn yourself if you neglect to do so!
Hey! I bought a color TV! Why is my screen black and white?
This is probably due to a bad color wheel. The way that the DLP television works is that the lamp passes light through a wheel with red green and blue sections. It processes the image in the three basic colors of light, and combines them to form what you see on the screen. When the color wheel goes bad, you'll either get a black and white picture that looks fine (the color wheel snapped off) or a distorted black and white picture. Contact a service technician to replace the color wheel. Sometimes you may have to purchase the whole light engine assembly, which is a bit costly. Be wary!
This is NOT a 3D TV! Why are the images all offset and layered?
This is a convergence issue. The image will look like it's repeated in red, blue and green tones or a combination of the three. You can adjust the static convergence from the TV's menus until the image lines back up. If this doesn't work, get it as close as possible. Dynamic convergence can be adjusted as well using a phillips head screwdriver. The only problem here is that you must open the back of the set and find the convergence board. Everything's labeled, and clockwise/counterclockwise rotation of each knob will help you to further align your picture. If that still doesn't work, then one of the circuits (red, green or blue) is bad on your board. I recommend getting a service technician to look at this issue if static convergence adjustments do not work.
