The Regza product line is Toshiba's line of LCD HDTVs. Screen sizes include the 42-inch 42RV53OU among the family of 32-inch, 37-inch, 46-inch and 52-inch LCD models. Toshiba LCD TVs are generally known for dependable, trouble-free performance. As with any electronic device, however, certain problems can occur. There is nothing particular to note about the Toshiba Regza 42RV53OU television that would not potentially occur with any other brand of 42-inch LCD TV.
Poor Color or No Color
More than likely, the station being watched is having broadcast difficulties. Switch to another channel. If that does not solve the problem, unplug the Toshiba 42RV53OU from its power source, wait 30 seconds, and then plug it back in and turn on the TV. If the picture problem still exists, try adjusting the tint and colour settings for the TV. You can access all menu options with the remote control.
Picture and Sound Out of Sync
This is caused by a variety of problems: video processing within the TV, different compression rates used by broadcasters or video processing in an attached component. It is usually remedied by adjusting the audio delay/synchronisation feature in an attached surround sound receiver, or calling your cable or satellite provider if the problem occurs on all channels. A fallback starting point is to turn off the TV and disconnect it from the power source for approximately 30 seconds, which will reset the 42RV53OU to its factory default settings.
Whether watching an over-the-air broadcast or cable/satellite channel, you may encounter a noisy picture with visual artefacts. This is different from poor reception. The Regza 42RV53OU has a CableClear/digital noise reduction circuit which can be set to "Auto." Change these settings by accessing the Video menu with the remote control, though you can also access all menus from the TV's right-side buttons.
General Picture Problems
These are general troubleshooting procedures. Check the antenna/cable connections to ensure that they're not loose. Press the "Input" button on the remote control and make sure an active video source is selected. Double check your picture with an outdoor over-the-air antenna, if possible. High-definition broadcasts are freely sent over the airwaves. Change the channel to make sure the picture problem is not just on the channel you're watching. Don't ever simultaneously connect more than one video source to any individual input.
