Frequently Asked Questions - TLP791 TOSHIBA

How do I replace the lamp on the Toshiba TLP791?
Turn off the projector and unplug it. Wait for the lamp to cool. Open the lamp cover on the side, loosen the screws securing the lamp module, and carefully slide it out. Insert the new lamp (model TLPLMP02), tighten screws, and close the cover. Reset the lamp timer via the menu.
Why is my projector overheating?
Check that the air intake and exhaust vents are not blocked. Clean the air filter (remove and vacuum or rinse). Ensure the projector is in a well-ventilated area. If the issue persists, the cooling fan may be faulty.
How do I clean the air filter on the TLP791?
Locate the filter cover on the side or bottom. Slide out the filter. Gently vacuum dust from the filter; if very dirty, wash with mild soap and water, dry thoroughly before reinserting. Clean every 100 hours of use.
What is the best resolution for the TLP791?
The native resolution is XGA (1024x768). For best image quality, use a source outputting at this resolution. The projector can scale higher or lower resolutions, but clarity may be reduced.
How do I adjust keystone correction?
Press the 'Keystone' button on the remote or projector menu. Use the arrow keys to correct vertical distortion until the image is rectangular. Adjustment range is ±30 degrees.
Can I connect my laptop to the TLP791?
Yes, use a VGA cable to connect your laptop's VGA output to the projector's 'Computer' input. You may need to press the 'Fn' key and corresponding function key (e.g., F4) to enable external display output.
What does a flashing red lamp indicator mean?
A flashing red lamp light indicates the lamp requires replacement or has reached the end of its life. Replace with a new lamp and reset the lamp counter via the menu. If the light continues flashing, check the lamp module connection.
How do I mount the projector on a ceiling?
The TLP791 is compatible with standard ceiling mounts. Use a mount that supports up to 4 kg. Attach the mount to the projector's screw holes (usually 3 or 4 points). Ensure the mount is securely anchored to a ceiling joist.
Why is there no sound from the projector's speaker?
Check that the audio source is connected to the projector's audio input (RCA or 3.5mm). Ensure the volume is turned up via the remote or menu. If using external speakers, verify they are connected and powered.
How do I reset the lamp timer?
After replacing the lamp, go to the projector's on-screen menu. Navigate to 'Options' or 'Setup' and select 'Lamp Timer Reset'. Confirm the reset. The lamp hours will be set to zero.

Notes

  • When the projector is moved from a cold location to a warm location, or when the ambient temperature in the projection room has risen suddenly, moisture may condense on the lens or the internal optical section to blur the projected pictures. In such a case, leave the projector for an adequate time (1 to 2 hours, depending on the room's condition) before using it, so it adjusts to the ambient temperature.
  • If the screen is exposed to direct sunlight or other strong light, the projected picture will become too faint to see. Shut out the light with curtains or by other means.
  • If the screen and the projector are not installed properly, the projected picture may be distorted.

About the LCD Panel

The life of the LCD panel is limited.

Take care over the points below so as to use the panel for years.

  • To prolong the life of this panel, never fail to turn the power off when the panel is not in use and make sure that the lamp has gone out. The state of the lamp being extinguished helps enhance the effect of energy saving.
  • If the air filter is stained and is clogged up, the main unit inner temperature rises. As a result, the life of the LCD is shortened and a malfunction may also occur. Clean the air filter from time to time 63 and replace it regularly. It is recommended that this replacement be done at the time of replacing a lamp. (Ask a dealer where the unit was purchased or your nearby service station about an air filter for replacement.)

TOSHIBA TLP791 - Press ON/STANDBY again. - 4

The standby mode is set.

Notes

  • The projector consumes about 20W of power in the standby mode. We recommend you unplug the power cord when not using the projector for long periods of time.
  • Be sure that the LAMP indicator has turned off before unplugging the power cord. Cutting the power by unplugging the power cord while the projector is operating or the light source lamp is being cooled will shorten the lamp's duration life. Should a fault or some other irregularity arise with this unit, unplug the power cord.
  • When reinserting the power plug before the lamp has cooled, please wait until the lamp has cooled sufficiently before use. When the lamp is at a high temperature, it may not light and it's life duration will be shortened.

Press AUTO SET.

The horizontal position, vertical position, sampling phase and sampling frequency are adjusted automatically.

The icon 📋 appears during signal processing.

Notes

  • Automatic adjustment may not be performed properly for signals other than those computers' signals with which the projector is compatible.
  • The horizontal position, vertical position, sampling phase and sampling frequency can also be adjusted from the menu screen 47.

\* Sampling frequency

Analog RGB signals input from the computer are converted into digital signals inside the projector. The sampling frequency is the number of times per second the analog signals are converted into digital signals. In order to capture (sample) each individual dot of the computer's signals, the sampling frequency must be adjusted to match the computer's dot clock frequency. If this adjustment is off, details of the image details may be blurred, a striped pattern may appear if images with many vertical lines are displayed, or the image's width may change. For computer signals with which are projector-compatible, the sampling frequency is adjusted automatically even when the AUTO SET button is not pressed.

\* Sampling phase

The sampling phase is the timing at which the computer's analog RGB signals are sampled. If the sampling phase is off, the individual dots cannot be sampled at the proper timing, resulting in blurred or flickering images.

Air filter cleaning

CONTENTS

CAUTION

If you use the projector mounted on the ceiling, ask the dealer to carry out the maintenance such as cleaning.

The filter inside the air filter cover is the part to shut out dusts or dregs.

Do not use the projector with the filter taken off.

We recommend you clean the air filter frequently. (The cleaning period is once per 50 hours approximately).

CONTENTS

Notes

  • When the air filter is dusty, the ventilation is impaired. This causes the temperature inside the projector to rise, and may damage the unit.
  • Attach the air filter cover firmly after the cleaning. If it is not set correctly, the dusts will enter and they will be projected and overlapped on the picture.
  • If you wash the air filter with water, be sure to let it dry fully before reinstalling it. Using it damp will result in malfunction.
  • If the air filter is damaged, contact your store of purchase and replace it with a new one. Using a damaged air filter will cause dust or dirt to get inside the projector and onto the images.

Notes

  • Signal sources marked “*” are displayed in compressed format, so some of their data may be missing or their picture quality may be degraded.
  • With analog RGB inputs, if the signal source's dot clock frequency exceeds 165 MHz, not all of the pixel signals can be sampled.
  • For digital RGB inputs, the projector is not compatible with signal sources whose dot clock frequency exceeds 162 MHz.

  • When commands are transmitted serially, wait for the reply of the projector (acknowledge or not acknowledge) before sending the next command.
  • Adjustment commands include "ARG" (increase adjustment value) and "ALF" (decrease adjustment value). For usable items (marked "Yes"), send after the selection command.
  • The "Yes" marks in the input source columns indicate that that command can be used.
