Question about Toshiba 43H70 43" Rear Projection Television

1 Answer

TV is on, but not displaying picture.

When I press the power button, the TV will turn on, but it will not display anything. The power button will blink on and off, however, and the TV is on. At first, I would hit the area around the power button and the picture would work. But now, it wont work at all and the light just blinks on and off.

Re: TV is on, but not displaying picture.

This unit is known for bad relay contacts. It may be that tapping in-on-or around the relay at Sr41 might restore the pic temporarily. If so, replace it - p/n#23146558.. If not, you may have some poor solder joints that will take a little bit more investigating and possibly shop time if you're not up to the task.

Replaced main bulb in front but lamp button on front of tv is still blinking and tv won't show picture

The lamp timer on the Hitachi projector must be reset whenever the lamp has been replaced. The "Lamp" indicator on the display will light red or the "Change the Lamp" message will display when the lamp timer needs to be reset. Hitachi recommends that the lamp timer never be reset without replacing the lamp and to always reset the timer when the lamp is replaced. The message functions of the projector will not function properly if the lamp timer is not correctly reset.

  • Turn the power on. Press the "Reset" button for three seconds until the "Lamp xxxx hr" message appears on the lamp timer on the bottom of the screen.

  • 2

    Press the "Menu" button on the remote control while the lamp timer is displayed.

  • 3

    Press the left arrow button. Select "0" and wait until the timer display clears.

  • If this was helpful a vote on the thumbs up for the free advoce would be greatly appreciated. Thanks

    I was wondering if you could tell me how to reset the timer after I have installed a new lamp. Can you help me? tv is a panasonic pt-56dlx25 Thanks, dave

    Plug the power cord back into the properly grounded wall outlet. Then press the POWER button on the projection display or the remote control to turn the power on.

    2. While pressing the VOL- button on the projection display, hold down the PIP or SPLIT button on the remote control simultaneosly for more than 5 seconds.

    3. Whe the lamp time reset procedure is complete, the screen will display "LAMP TIME WAS RESET TO 0." When the lamp time is reset, the LAMP indicator will go out

    No geen colour!but great pic and sound

    sure turn up your screen control for that color slowly if color comes back then the adjustor is just dirty (no repairable) make sure you don't see milky white lines or a solid color on a blank input.
    put the unit on a video position that has no source so the tv displays the input label but nothing else.
    slowly adjust the screen control( behind the front grille little black box with 6 little knobs on it)
    untill you start to see the coresponding color then back it off till the color is gone, you are done.
    if this doesn't work then check your video path from jungle to crt output, your output chip may ne fried

    I was tring to remove the concave off my screen and came across a setting where you can make the picture larger or smaller. On the TV, not the remote, press and hold the menu button, press and release the power button, press and release the volume up button and release the menu button. P0 and V0 will be displayed on the screen press the volume up button until the V0 is V76. Press the channel up button until P0 is P11 and press the volume up/down button to make the picture larger/smaller. If you need to center the picture press the channel down button until P11 is P10 and press the volume up/down button to center your picture. I hope this helps

    Picture is a little fuzzy and does not fit the screen

    Good Day, mopar69;

    Try this and if does not work, call SONY TV with Model and Serial NUMBERS, this sounds like you may have a defective light engine, and they are having problems with them, and they , Sony, are covering that device.

    Restoring unit to Factory Preset Condition

    1) Power off the set (set is now in Standby Mode).
    2) On the remote, Press DISPLAY, CHANNEL 5, VOL +, POWER.
    3) On the Remote press CHANNEL 8, ENTER.
    4) Wait until Initial Setup is displayed.
    5) Turn off TV sets power by the Remote or Front Panel button.
    6) WAIT AT LEAST 3 MINUTES UNTIL THE LAMP COOLS DOWNS BEFORE UNPLUGGING OR DISCONNECTING THE AC FROM THE TV. If the set is not allowed to cool down the lamp may be damaged by excess heat build up.

    I hope this was helpful, Good Luck, big IRISH.

    Heres how you get into the service menu. BUT be very careful write down anything that you change as this can screw your set up and if you write down everything you will be able to change it back if it affects your set. You may want to consider getting the service manual which will explain all the details on the convergence adjustments. If so let me know and I will post a link where you can get one along with free tech support to help you out with it.
    Put the TV in Standby Mode.
  • Then press the following buttons on the remote:

    {DISPLAY} {5} {VOL+} {POWER}
    {DISPLAY} {5} {POWER}

  • The TV will turn on with the Service Menu displayed.

  • Use numbers {1} and {4} to select the item to adjust.
  • Use numbers {3} and {6} to adjust the value of the data.
  • Press {MUTE} then {ENTER} to save new settings.
  • The words "WRITE" in red will show up in the upper right corner if saved.
  • Turn the TV off to exit the service menu.
