Projection TV Troubleshooting Guide

Projection TV troubleshooting can get extremely complicated, but most people can at least begin the process on their own. If you're patient, methodical and determined, chances are good that you can figure out the problem and maybe even make a repair yourself.

Troubleshooting Basics
Begin with some obvious things that can fix simple problems. Unplug the projection television and then plug it back in again. Check the outlet to make sure it's receiving power. Make sure the cable to the television is fully connected. Ensure there's clear air flow around the television and that it isn't overheating. If you're still having trouble, move on to your owner's manual.

If you can't find your owner's manual, don't panic, just type the brand name of your televison into an Internet search engine. Most manufacturers have digital copies of owners manuals online, so you can print out a new one. You may need the model number of your television to get the right manual, which you should find just above its serial number on the back of the cabinet.

The owners' manuals for projection televisions list common problems and their fixes in the back. Work through the list, one test at a time, to try and narrow down the problem. When you're troubleshooting, the key is to try one thing and see if it works, then undo the change and move on to the next item.

If the owner's manual doesn't offer a useful fix, try looking in online forums for information about your TV. chances are good that other people have encountered the same issue you have with your projection TV, and they may have a solution for the problem.

Common Projection TV Problems
The most common problem with projectors is a burned-out bulb, either the light source used for rear projectors or one of the red, green and blue bulbs used in older front projectors. You'll often need to order replacement bulbs from the manufacturer, but you can try searching for online stores that offer these bulbs at a discount.

If the picture is blurry or the colors smear, it's usually a sign that the projectors are out of alignment. You can often fix this yourself using on-screen menus that calibrate your television. Projectors should be adjusted any time the set is moved and about once a month to make sure you're getting the best picture possible. 

Call a Professional
Troubleshooting can be a time-consuming and frustrating process. If you've tried a few things but simply don't have the time or the inclination to poke around further, it's time to call a repair company. Some projection TV repairs can't be completed by home users anyway, so hiring a repair person maty be your only solution.
