My computer will not turn on anymore


Try connecting the power-cord to a different wall-plug.

Look on the back for a "rocker" switch.
Flip it to the other side, and try the ON/OFF button.
If nothing, flip it back.

Open the case, and look for any small lamp on the motherboard.
If it is not lit, then the motherboard is not getting any power from the power-supply. Try a different power-supply.

Open the case, and look at the wires coming from the back of the front-panel to the motherboard. Look for any loose or non-connected wires. If one pair of "loose" wires is labelled 'POWER SW(itch)', then reconnect it to the appropriately-labelled pins on the motherboard.

If all else fails, take the computer to a qualified technician, for "hands-on" trouble-shooting.

My laptop screen appears to have a short somewhere. Occasionally the screen becomes scrambled, but swiveling the top at the hinge helps. Sometimes I have to put pressure at the hinge by holding the screen...


This sounds like the ribbon cable that runs from the system board to the display is starting to fail. Before replacing it, you may want to check the connection at the display end and make sure that it is secure. Many manufacturers use a silver tape to secure the plug into the socket. If this tape has lost the adhesive over time, the plug may be starting to work its way out. If all connections are secure, replacing the cable is the best bet.

Unless you are highly familiar with the disassembly procedures for your laptop, I would recommend downloading a service manual for your specific model before attempting this.

C-D370 error code for Copier KONICA-MINOLTA C252


this has to do with what they call NAVRAM IS C
To troubleshoot the error:
1. Reset the code by pressing stop-0-7-1-3-9. This will display a "*" on the LCD. Press this button.
2. Perform a Data Clear and then perform the Setup Procedures from the beginning.
3. Perform a NVRAM Recovery Procedure. Please see attached document. To view the PDF, Adobe Reader® must be installed. Adobe Reader® can be downloaded for free from RRUPTED/need to be reset BUT that will clear all the current setting especially if print to it.if you are willing to try ....
you should have a Tech do this...
good luck

HP Laptop black screen on boot, TV source works


You most likely have a defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
Check out www.lcdparts.net for parts, repair service and DIY info.

No Display, monitor won't come on.


hi try this or the site below
Monitor Problems:

THE COMPUTERS SEEMS TO BE WORKING, BUT THE SCREEN IS BLANK.
- Check the monitor if turned on.
- Check all the LED power on the monitor, if it has one.
- Adjust brightness and contrast controls all the way to the maximum.
- Check the video cable from the monitor to the computer to be sure if it is properly connected.
- Check the power cable. If it is connected properly at both ends.
- Try different monitor on your computer. If it does not work, the display card is likely at fault. Replace the display card.
- Try your monitor on a different computer. If it does not work, replace the monitor or have it repaired by a trained technician.

COMPUTER BOOTS, BUT DISPLAYS “JUNK” ON THE SCREEN
- It may be that the display card is defective. Try a different card. If it works the first card may be bad.
- Try the suspected bad card on another computer. If it displays the same thing it is conclusive that the card is bad.

DISPLAY IS DIM, OVERLY BRIGHT, OR BLURRY, OR UNPLEASANT.DISPLAY IS OFF CENTER. LEFT OR RIGHT SIDE OF MONITOR IS OBSCURED.
- Try adjusting the control knobs located on either the front or back of the monitor. It maybe necessary o open the monitors casing to get the proper adjustment controls. In this case be very careful because there are high voltages in the monitor.
THE VIDEO DISPLAY FADES AND BRIGHTENS, OR IS WARY.
- The voltage may be fluctuating due to so many appliances or electric devices on he same branch circuit.
- Turn off other appliances and peripherals, such as printers, external modem, refrigerator, microwave oven, transformer, etc. and see if that solves the problem. If the problem persists, try swapping out the display cards. If changing the monitor solved the problem, repair or replace the monitor.
IMAGE IS NOT STRAIGHT ACROSS THE SCREEN
- If the monitor is still under warranty, bring it back to the dealer for adjustment. If the you want to do it your self, bare in mind that this is potentially dangerous procedure because it must be done while he monitor is on and there is very high voltages around the picture tube.
WARNING: THIS IS A DANGEROUS PROCEDURE!!!
- Open the monitor casing and loosen the clamp holding he coils around he picture tube. You can loosen them (usually there’s a wing nut) and a rotate the coil assembly until the picture strengthens.

Help me please with my phone!!!


Hi Ya! The problem could be with the bus that connects the key pad with the screen area. The way you open and use and the frequency of open-and-shut ruins the main contact data bus cable and evena single break can cause such phones to act the way you are describing. Take it to the Local Samsung Service Centre and get the Data Bus checked for damages and or else get the base s/w reloaded (Virus). Keep your phones BlueTooth OFF while you are moving in public, as viruses can be uploaded without YOU even noticing! Back up data and get the phone formatted. This should HELP solve!
