Screen frozen i can not power down or change screen. my screen is forzen

Try holding down your power button and home button at the same time for about 10 seconds. If that does not work, you could try to hold them both down for about 3 seconds then let go of the power button and continue to hold down the home button for about 7 seconds.

did u try to reset the device

The instruction for resetting to factory defaults can be found on page 27 in the manual, which can be viewed here:

You can contact the manufacturer to see if they have any troubleshooting tips but it sounds like the dvr is shot. Sometimes the manufacturer will take them back and repair them, if there's been a recall on that particular model they will repair or replace for free!

You are asking too much too quick from your AC - and/or - you have a restriction in the air supply. Don't allow the AC to continue to operate while frozen. Check that you dont have a colapsed return air hose.

Let me know what you find.

Key board or mouse not work mean one of four reasons

1- kb or mose is damaged (replce it )

2- ps2 socket is damaged (can be replaced )

3- Resistance No 472 on motherboard is damaged (can be replaced )

4- I/O IC is damaged (i think no repair )

easy solution you can buy a (usb-ps2) converter

best regardes

TAKE OUT THE BATT AND PUT IT BACK IN THIS WILL REBOOT YOUR CONTROLL YOU SHOULD ALSO UPDATE YOUR SOFTWARE AND FRAMEWARE THIS WORKS

the software may have got corrupted.

better get it reprogrammed to bring it back to working condition

One of the reasons might be a filesystem panic. Run a chkdsk /F/X/R in a dosbox on a windows machine, it will take some time and some files might be lost but the filesystem will be fixed.

It helped on mine.

Well, not a long time ago I have had a similar trouble regarding to my Texas Instruments Calculator Voyage 200. It was forzen too doing some calculus. Also, one friend had a similar problem regarding to the fozen calculator... I fixed it by reading in the manual that it can be reset!!!...There is a combination of keys that you can press to reset the calculator...this obligates the calculator to load the OS from the EPROM memory where is this basic sofware!!!... If I do not remember wrong the keys are: 2nd + Lock + on/off keys!!! But try to look for the manual and in some part of it is those key combination!!! Good Luck!
