There is a "mute" screen which will hide the picture on your projector. If thats not the case there seems to be a problem with the remotes/controls fo rthis projector, as my functions do not workcorrectly all the time.
Lastly, the red x in the upper corner meant that you had no signal going to the projector, and would have no effect on shutting down.
Hope this helps

Unlock apex tv model # AT2702


  • If you have a blank screen with a red key on the bottom left, simply press the (function or F) button and the mute button at the same time. This will unlock the screen and allow you to view the channel as desired.

  • If your TV asks for a 4-digit code or password please enter 3308 or 6688 to unlock the screen or reset any preset rating levels.

  • If you have a GT2011J or GT2011S Television, hold the (Display) button for 10 seconds, it will unlock the screen. If password or code is requested, try 3308 or 6688.
Hope that helps..........

It doesn't show red color. i tried to do factory reset. but still problem.


1.After turning on the projector, press "+" and "-" buttons on the control panel
simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3 While in Self-diagnostic mode, the screen will run a seven-color-cycle test as
following:
Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct.

Contact Dell if the colors are not displayed correctly.

Blinks blue then green and turns off after that.


All of these sets had bad picture tubes--the tubes are no longer available--can only be got on a rebuild basis--very expensive----Blue tube seems to be the most common to go bad.

If the screen goes bright blue the set will shut down as the set detects too much current is being pulled by that tube--

Other than replacing the tube you do have one option that may resolve your problem--it may return the set to operation----it also may just only buy you some time.

These sets have a black plastic block located behind the front speaker grill--there is a inspection plate behind the grill and behind it is the square black plastic block with 6 controls molded into it----it is the Screen/Focus block.


I can tell you how to get at it---what you want to do if you do this is get the grill and inspection plate off and locate the block.

There will be two rows of 3 controls---one row will be marked Focus---do not touch those.

The other row will be marked SCREEN---you have to look very close to see which is red, green, blue.

With the front grill and inspection plate removed you turn the set on----have it on a Video input2.gif with nothing connected to it---if you locate the Blue screen control you turn it to the left until you do not see blue or curved blue trace lines---if you turn it the wrong way the set will shut down---

Once you get the blue set---look at the screen on the blank input---you should only see the video input display---if you see some green or red you need to adjust those controls also.

Understand--even if this works--you may only be buying some time--if one of the tubes caused this sooner or later it may happen again.

Let me know if you have questions or need advice.

The screen was green with lines through it. Periodically it will flash and power off. Now it's all blue and will not stay on.

Unit turning off after displaying red pc chip icon


Hi whitiezn

If you say that this unit is very new , it should on all accounts still be under warranty.

Contact your local Toshiba Service Centre and have this problem sorted out on their account - the machine should still be under warranty.

Big blue dot


This is going to hurt..
You probably have a polarizer failing on one of the LCD panels inside.
There are 3 of these in LCD projectors, red, green, and blue. They all get the light fed into them, that light is then combined and fed through the projection lens.

You will need to contact Sanyo to find a service centre to replace it.

Yellow area in the projected image


Hello Media Man,

Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color.
Good Luck.
