Sreen works then stopped worked agin now nothing

Unless you have been printing huge amounts of receipts or journals in one go, it should never show this error. It is most likely a thermal sensor (thermistor) problem. Have the printer checked.

is the compressor running? can u hear it? the defrost timer may have gone out and stopped on defrost? do u see or hear the fan going? u can manually turn it off defrost by inserting a small philips screwdriver into the tiny hole or slot under the defrost timer in the fridge. and turn it clockwise till u hear it click this will turn the defrost cycle off and u should then hear the motor and fan come on? this will give another 8 hours before it gets stuck agin andf u have to go in and turn it off agin till u replace the timer or cold control thermosttat

The problem you are describing is in the electronic timing module and there is nothing you can do but return it to the place of purchase for exchange.

Two things I can think of. First make sure the pressure switch ports and tube are cleared of debris (be careful not to blow or stick anything into the pressure switch itself. clear the port in the inducer housing with a paper clip or hanger.
The second thing is that the gas valve may be failing. sometimes they will turn on at first and then just stop giving gas. If this is the case it should be replaced. I hope this works for you :)

look there is a problem with the touchbad diver and this is common but the keyboard must work it s nothing with the keyboard so please check if all the key board works under another operating system and then if it wrks try to reinstall windows 7 again and it must work conntact me if you still have a keyboard problem you must try to plug a usp keyboard and see if it work so you have a problem with your board again if it worked you have a problem with your keyboard if it didn't work then try install windows 7 agin

my hpcompac nc6000 doesnot pick up the fan rolls but no display on the sreen

You need to check if the issue is with the LCD or with the video card. Please try to connect the laptop to a different monitor or another display device. If you get display or any images then you need to get the lcd replaced otherwise its a video card issue.

Try holding the display button for 10 seconds, worked for mine, unless the vcr presents a different issue

Justy a piece of junk. The display has nothing to do with the defrost. Hold your top two buttons for 10 seconds and the displays will reset..good luck.*****
