Troubleshooting

If you experience any of the following difficulties while using the TV, check the list below before consulting your dealer.

Interference

Please note the following common causes of TV reception interference:

Ignition Noise

Black spots or vertical lines may appear. Screen jumps crazily or is very unstable. This is commonly the result of car ignition noise interference, neon lights, or other forms of electrical interference.

Ghost Shadows

This is the result of two signals: one being the original signal while the second sig- nal is a slightly delayed signal, normally the result of bouncing off tall buildings or other obstructions. This problem might be corrected by adjusting your outdoor antenna direction.

Flurries

Lots of tiny dots appear on your screen. This is the result of poor reception signals. You may have to boost your antenna signal.

Common Problems

You may have problems that can be fixed with a few minor adjustments. Look for the type of phenomenon you are experiencing in the following lists and then apply the suggestions to resolve the problem.

Picture with no sound

Check if you have accidentally pressed the MUTE button.

Check if the same problem exists on other channels. If the other channels can be viewed correctly, then there is probably a fault in the TV program you are viewing.

Verify all connections are firmly attached.

If the problem persists, contact your dealer.

Sound with no picture

Check brightness and contrast levels to see if they have been tuned to the min- imum level thus making the screen dark.

No Picture No Sound

Check the main power source.

Check if the same problem exists on other channels. If the other channels can be viewed correctly, then there is probably a fault in the TV program you are viewing.

Press the TV/AV1/AV2 button on the Remote Control or TV/VIDEO on the top of the unit to get to the desired display option.

If you are using an outdoor antenna, please check your connections.

Check if your power cord is connected properly; it may be loose.

Disconnect cable. Reconnect cable.

Ensure that the antenna and cable are properly connected to the TV.

Ensure that the AC adapter and power cord are not damaged.

Test the antenna or cable on another TV.

If the problem persists, contact your dealer immediately.

Picture too dark

Check your brightness level.

Check your contrast level.

Load default setting. (See “Load Default Setting” on page 22.)

Check your LCD monitor for possible damage.

20DL74, 14DL74 specifications

The Toshiba 14DL74 and 20DL74 are notable models in the realm of consumer electronics, specifically in the category of CRT televisions. Although CRT technology is largely supplanted by LCD and LED displays, these models are revered for their unique characteristics that appeal to a niche audience, especially among retro enthusiasts and collectors.

The Toshiba 14DL74 features a 14-inch screen, while the 20DL74 boasts a larger 20-inch display. Both models utilize a traditional cathode ray tube (CRT) technology, which produces deep colors and rich contrast, often praised for its ability to deliver a more immersive viewing experience compared to some modern displays. This technology is especially appreciated for its capability to handle a wide range of video signals, making it compatible with various formats.

One of the standout features of these models is their excellent picture quality. The CRT screen provides sharp images and vibrant color reproduction, making them ideal for enjoying classic video games and films. The 14DL74 and 20DL74 support multiple input options, allowing users to connect various devices such as VCRs, DVD players, and game consoles easily. They are equipped with composite video inputs, and some models include S-Video connections for enhanced picture quality.

Another significant characteristic is the durability of these televisions. CRTs are known for their long lifespan and robust construction. The Toshiba models are built to withstand everyday use, which is a considerable advantage over some contemporary flat-screen televisions that can suffer from issues like dead pixels and screen burn-in.

The audio performance of these models is also commendable. Each television includes built-in speakers that produce clear sound quality, suitable for everyday viewing. However, for users seeking a more immersive audio experience, connecting external speakers through the available audio outputs is a straightforward process.

In terms of design, both models feature a timeless aesthetic that fits well in retro-themed setups, adding a nostalgic touch to any space. Despite their bulky nature compared to modern TVs, the appeal of their visual technology and the authentic viewing experience they provide continues to attract interest.

In summary, the Toshiba 14DL74 and 20DL74 represent a bygone era of television technology that still holds value for specific audiences. With their durable construction, rich color performance, and compatibility with vintage media sources, these CRT models offer a unique experience that is hard to replicate in modern display technologies.
