How to Troubleshoot a Samsung Projection TVby M. Wade
A projection TV is a popular type of television that uses a beam of light inside the television to convert a small picture into a larger picture to display on the screen. Samsung offers several models with features including HDMI inputs, a range of HDTV resolutions and brand-specific technologies such as CinemaPure for a brighter display. If, after setting up your Samsung projection TV, you have trouble hearing the audio or the picture is distorted or will not display, you'll need to troubleshoot the problem and determine whether you can fix it yourself.
Check that the TV speakers' setting is "On." Access the "Audio Settings" menu on your remote to adjust your TV speakers' settings.
Check your "audio out" cables. If you hear audio from only one side of your TV or home theater system or cannot hear any audio, check that your audio cables are completely inserted into the TV's "audio out" ports. If you're using a separate home theater system, check the connection of the audio input ports on the home theater system.
Connect digital and analog A/V cables. If you're using a separate home theater system or other external speakers with your Samsung projection TV, you may not always be able to hear audio if you are using only digital audio cables. Digital audio cables will not receive the audio signals from any type of analog source. If you're solely using a digital audio cable and cannot hear audio on certain (analog) channels, use analog A/V cables in addition to your digital audio cables.
Check your cable/satellite connection. If the picture on your Samsung projection TV is fuzzy or grainy, check that all of your video connections are secure. Tighten all of the cables leading to your cable/satellite box and television and any cable splitters. If you're viewing a low-quality analog or digital channel (i.e., 480i), the picture will always remain fuzzy if your projection TV always displays in 1080p. Such projection TVs will show a clear picture only when the signal viewed is in 1080p. Contact your cable or satellite provider to learn how to receive channels in 1080p. If your picture looks stretched, access the "Picture Settings" menu to change the aspect ratio.
Scroll through the source inputs. If you do not see any picture, press the "Source" button on your remote to check that a connection is detected in one of the video inputs. If you still cannot see video, press the "Antenna" button to scroll through the RF connections on the TV.
Move the TV. If you notice small, hazy white spots on your Samsung projection TV, this may be due to a glare from a nearby light source, such as a fluorescent light or sunlight. To avoid glare spots, move your TV so that the rear of the TV faces the light source. Other common causes of picture disruptions are a faulty power outlet and RF interference. Try plugging your television into another power outlet and turning off other electronic devices in the area. These include vacuum cleaners and other high-power devices.
Replace the lamp. The lamp that projects images onto your projection TV's screen has a limited lifespan. It will need replacement every few years. If your TV fails to produce any picture and repeatedly makes a popping noise when it is powered on, replace the lamp. Another way to tell if the lamp needs replacement is if the lamp LED indicator on the front or top of the television blinks repeatedly. You can order and install a compatible replacement lamp from Samsung's website or seek the assistance of a television repair specialist.
- If these steps do not correct your audio or picture problems, consider completing an online service request via Samsung's website or taking your TV to a television repair specialist.
- To prevent image burn-in, avoid displaying still images on the screen for extended periods.
