10 Troubleshooting

Before calling a service technician, please check the following table for a possible cause of the symptom and some solutions.

Symptom

Solution

 

TV will not turn on

• Make sure the power cord is plugged in, and then press POWER.

 

 

 

 

• The remote control batteries may be dead. Replace the batteries or try the front panel buttons.

 

 

 

 

• If you have recently replaced the lamp unit, make sure the lamp unit and lamp unit door are installed

 

 

 

 

properly (pages 103–105).

 

 

 

 

• The lamp unit may need to be replaced (pages 103–105). Also see “LED indications” on page 99.

 

 

 

 

 

 

No picture after TV is turned on

• When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for

 

 

 

 

the picture to appear on-screen. See "IMPORTANT NOTICE ABOUT HOT LAMP RESTART" on page 8.

 

 

 

 

 

 

Picture problems

• Check the antenna/cable connections (Chapter 2).

 

 

 

 

• Press INPUT on the remote control or TV/VIDEO on the TV front panel and select a valid video input

 

 

 

 

source (page 67). If no device is connected to any of the inputs on the TV, no picture will display when

 

 

 

 

you select that particular input source. For device connection details, see Chapter 2.

 

 

 

 

• Antenna reception may be poor. Use a highly directional outdoor antenna (if applicable).

 

 

 

 

• The station may have broadcast difficulties. Try another channel.

 

 

 

 

• Adjust the picture qualities (page 79).

 

 

 

 

• If you are using a VCR, make sure the TV/VCR button on the remote control is set correctly (page 26).

 

 

 

 

• If you have two VCRs connected to your TV, do not connect the same VCR to the TV’s output and input

 

 

 

 

connections at the same time (page 18).

 

 

 

 

• Do not connect a standard video cable and an S-video cable to VIDEO-1 or VIDEO-2 on the TV back (or

 

 

 

 

VIDEO-3 on the TV side) at the same time (Chapter 2).

 

 

 

 

 

 

 

 

Noisy picture

• If you are watching a tuned analog channel (off-air broadcast or Cable TV), set the CableClear®/DNR

 

 

 

 

feature to AUTO to reduce visible interference in the TV picture (page 80).

 

 

 

 

 

 

 

 

Video Input Selection

• If the Input Selection window does not appear when you press INPUT on the remote control or

 

 

 

problems

TV/VIDEO on the TV front panel, press INPUT or TV/VIDEO a second time, which will change to the next

 

 

 

 

video input source and display the Input Selection window.

 

 

 

 

 

 

 

 

Cannot view external signals

• If you cannot view signals from external devices connected to VIDEO 1, VIDEO 2,

 

 

 

or channel 3 or 4

VIDEO 3, or ColorStream,® or from channels 3 or 4, make sure the Input Lock is set to Off (page 95).

 

 

 

Black box on screen

• Set the Closed Caption feature to Off (page 82).

 

 

 

 

 

 

 

 

Poor color or no color

• The station may have broadcast difficulties. Try another channel.

 

 

 

 

• Adjust the Tint and/or Color (page 79).

 

 

 

 

• When the ColorStream® signal source is active, the VIDEO OUT terminal outputs blank video. To receive

 

 

 

 

video from the VIDEO OUT signal, a standard video or S-video IN terminal must be used instead of the

 

 

 

 

ColorStream® connections.

 

 

 

POP problems

• The VIDEO OUT terminal will not output the POP picture (pages 18 and 76).

 

 

 

 

• If you label all of the inputs as “Hide,” the POP feature will be disabled. If you then attempt to access the

 

 

 

 

POP feature, the message “Not available” will appear on-screen (page 68).

 

 

 

 

 

 

 

 

Picture brightness changes

• If you set the lamp mode to Low Power, each time you turn on the TV, the lamp will start out in High Bright

 

 

 

soon after turning on TV

mode but will switch to Low Power mode in approximately 1 minute. You will notice a change in screen

 

 

 

 

brightness when this happens. This is normal and is not a sign of malfunction. (See page 75.)

 

Picture and sound are out of sync • As with all products that contain a digital display, in rare instances, when viewing certain content (e.g., television broadcasts, video games, DVDs), you may notice that the picture and sound are slightly out of sync. This phenomenon can be caused by various factors including, without limitation, video processing within the TV, video processing in an attached gaming system, and video processing/different compression rates used by broadcasters in their programming. You may want to try one or more of the following suggestions, which may help to reduce the effect of this phenomenon:

-If the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchronize the sound to the picture.

-If you notice this phenomenon only on certain TV channels, please contact your local broadcast, cable, or satellite provider to inform them of this issue.

Memory card

• Make sure you are using a supported or valid memory card format (page 87).

problems

• Make sure you have saved the picture files in the correct file format (page 87).

 

 

• The card may be inserted improperly. Remove the card and reinsert it (page 88).

 

• The memory card may be empty.

 

• The memory card may be damaged.

52HM95, 62HM95 specifications

The Toshiba 62HM95 and 52HM95 are part of Toshiba's renowned line of rear projection televisions that made waves in the mid-2000s for their picture quality and innovative features. These models are particularly noted for their large screen sizes and advanced technology that appealed to home theater enthusiasts.

Starting with the display technology, both models utilize DLP (Digital Light Processing) technology, which provides enhanced brightness levels, deep black levels, and impressive color accuracy compared to traditional CRT televisions. With the 62HM95 boasting a substantial 62-inch screen and the 52HM95 featuring a 52-inch display, both models are designed to offer an immersive viewing experience suitable for larger rooms.

The key feature that sets the Toshiba 62HM95 and 52HM95 apart is the incorporation of Toshiba's advanced imaging technology, including HQV (Hollywood Quality Video) processing. This feature enhances the picture quality by improving image sharpness, and reducing noise in lower quality video sources, ensuring that film and sports experiences are smooth and visually appealing.

Moreover, these models are equipped with 720p high-definition resolution, offering a display resolution of 1280 x 720 pixels. This level of HD ensures that viewers can enjoy their favorite movies and shows in sharper detail than standard definition. The utilization of a color wheel in combination with the DLP technology contributes to vibrant color reproduction, making for engaging visuals whether you're watching a blockbuster or a nature documentary.

Connectivity is another strong point of the Toshiba 62HM95 and 52HM95. Both models feature multiple inputs, including HDMI ports, component video inputs, and composite video inputs, making it easy to connect various external devices such as game consoles, DVD players, and set-top boxes. The inclusion of an integrated digital tuner means that users can easily access over-the-air HD broadcasts without needing an additional external box.

In terms of design, the Toshiba models present a sleek and modern aesthetic, with a minimalistic bezel that maximizes the screen view. The use of a rear projection system means they are relatively deep compared to flat-panel TVs, but this is a trade-off for larger screen sizes at a more affordable price point.

Overall, the Toshiba 62HM95 and 52HM95 remain notable options for those looking for effective home entertainment solutions. With features like DLP technology, HQV processing, and strong connectivity options, they provide an excellent foundation for building a satisfying home theater experience. Their combination of screen size, technology enhancements, and user-friendly connections makes them a consideration for anyone seeking to enjoy high-quality content in their living spaces.
