Hello

Your TV is locked. Do the following to unlock it.

Apex TVs use a four digit code to control the v-chip. The override code for many models is 6688. Other sets may not have one, or may have a default code of 1225 instead of an override code.

1. To use the override code:
2. Hit the MENU key to get to the menus.
3. Go down to the SYSTEM menu and hit the right arrow on the remote control.
4. Once in the SYSTEM menu, go to PARENTAL GUIDE. It will ask for your code.
5. Enter the override code listed above. From here, you can turn on and off different rating restrictions, as well as set a new code.

No matter what the V-chip code is set to, the override code will still work. 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 desiredOK.

That is the OSD (On Screen Display) system built-in to your computer monitor. Check that when you hit the ON/OFF button on your monitor, that you do *NOT* hit the 'OSD ON/OFF' button.

Most of the time, the OSD will disappear after 10 seconds of "non-use".

This link will take you to the monitor setup menu where you can correct your screen position problem.

Good Luck,

The problem was repaired by, Calling gateway. You pull up the challange code #'s on the monitor. You tell gateway agent the code numbers, they tell you a unlock code. You enter that on your monitor. and thats that! You pull up the challange code by unpluging your monitor then hold the menu button on monitor. plug back in holding the menu button! larrygl.

Try a hard reset: Unplug from power source, disconnect from PC and wait for 10 minutes. Reconnect everything and see if the issue is resolved.
If not, then you either have a loose contact on the menu button or failing circuitry. I'd recommend calling Sharp tech support in this case..

It sounds like an issue with the power button board and I would certainly make use of the warranty option.

Hold the menu button until the padlock unlocks, it takes anywhere from 30 seconds or even a minute or so

I have the same problem except it usually happens after Ive left my computer idle for a while... i.e . Overnight, I usually turn off the monitor and I hit the button after I come back to turn it on. I get the same flashing light for several minutes. This has been a problem for several months, but only recenly have i gotten the same error message you mentioned. Each time ive booted the computer up cold or restarted it has worked fine but this time it took longer along with displaying the message: Top Left to Right: SH770 P001 Bottom Left to Right: AU M170EN05 Anyone else who can clear this up?
