Sometimes this can be caused with memory problems Reseat the memory by switching off the G5 then take out the memory and replace it back. It could be that it is slightly loose. Hope this helps.

I've had my Sharp Aquos LC20E1U for a number of years. A couple of times recently it just shut off on its own. It started OK again the following day. However, last time this happened, it wouldn't even...

service menu procedure text changed by midge to work with Sharp LC-32P70E & probably the same for similar models.

There are probably ways of really messing up your set if you do the wrong thing from the service menus, so do this at your own risk:

To enter service menu, make sure the set is plugged in but turned off at the power button on the top of the tv,
then while holding both input button and volume down button, push the power button. Within about 5 seconds, the set will power up keep holding the input and volume down buttons until a small "K" appears in a box on the left side of the screen. Then press and hold the channel down and vol down buttons at the same time to enter the service menu.

Once the service menu is displayed on the screen, you can get the screen to display different levels of solid grey by pressing the number keys on your remote. i.e. press "1" to get a relatively dark grey, 2 for a lighter grey, and so on up to 6 which is a bright white screen; 7, 8, and 9 don't appear to do anything. (this was for adjusting grey levels, other settings are available too) Press any number a second time to return to the service menu...

Not sure wether the grey background settings apply, but for entering the service menu it does.

I think to get out of service mode you have to disconnect the TV from the mains and wait about 30 seconds.

it's some time since I used the service menu on the Sharp Aquos but I do remember you can do a full reset to factory settings as well as turn on, off and reset certain system settings too you will just have to experiment with the remote keys, I think the colour fastext key access different menu levels etc but as I said I am unsure, at least this procedure will get you there so you can try for yourself.

Hope this helps

Please come back to let me know if the service menu procedure works for you.

Good Luck

Midge.

C700 laptop's display problem

I have the same issue. 


Problem appears only while working with power adapter.

When I turn off power adapter (so notebook is working with battary) everything is OK.


It is somehow connected with shutting down. If disconnect power adapter durring shutting down - next time you will have problems with grey screen.

Don't know how to fix it.
Usually solve by making several reboots and to turning on/off power adapter.

Lamp time

Hi

You will have to reset the lamp timer as follows :

Hold down the up arrow key on your projector for a couple of seconds - projector must be switched on.
You'll see a on screen message appear in one of the top corners on the image....then just follow the two basic steps as requested on screen.....your lamp timer will now be reset.

Then shut down the projector and restart for changes to take effect.

I think what is happening here is a side effect of power saving. When your Mac goes to sleep, it powers down the usb ports. It sounds like it loses connection with the printer and the first print command re-establishes the connection. Try setting your computer to never sleep and see if that helps.

and shut down applications. To see what applications are running keep your finger on the menu for 2 seconds, press C to shut these down. Then try again if it still doesn't work, their site is probably not WAP friendly.
