RCA Projection TVs display dynamic picture quality for home viewing pleasure. They are not, however, immune to various video and audio issues. Spotting and preventing these problems, as well as addressing them when they arise, can help your TV last longer and may save you a costly repair bill.
Picture
The screen on your RCA projection TV may remain blank after being turned on. It may also be fuzzy or snowy, blink on and off or go out altogether. Ensure that all video cables are securely connected to receive a good signal from the source. Also, do not subject the TV to long periods of use. If an image remains paused or unchanged on the screen for too long, it can become burned in, which means it will be permanently imprinted as an after-image.
Convergence
Rear projection TVs that use cathode ray tube (CRT) technology have three tubes that control the red, blue and green parts of the video. These can fall out of alignment if the TV gets jarred or after a long period of use. This causes a halo effect and a ghost image on the screen. Most RCA projection TVs have an auto-convergence option to remedy this. Some models allow you to adjust it manually as well.
Audio
Projection TVs can have their share of sound problems--low or muffled sound, static or noise interference, no audio while the picture is on or one or both speakers going out. In most cases, professional repair is needed address these issues. If the coils vibrate and cause a loud, high-pitched tone when used with certain components, repair is also necessary.
Remote Control
If the remote control is unresponsive, clean it with a damp cloth to remove any dirt that accumulates near the buttons and around the infrared sensor. Aim the remote directly at the sensor on the TV and press the TV button to ensure that it's set to that particular device. After a long period of use, the buttons on the remote control may become worn down. In this case, the remote control must be replaced.
Power
If the TV shuts itself off, refuses to turn off or turns on and off intermittently, it could be overheated. There may also be a bad connection to the AC outlet or perhaps even a larger issue. Unplug the unit for a while and try using a different outlet.
Daily Maintenance
Other problems can be prevented simply by taking good care of your TV. Avoid overheating by not placing the unit near heating vents, and turn it off whenever it is not being watched. Clean the screen with a soft cloth. Do not spray cleaning liquid anywhere directly on the unit, and dust it often to keep dirt from getting inside the workings and on the circuitry.
