In wespro netbook the boot screen did not appear, it shows blank and blank, can you help me ?


Test all leads that attach to your hard drive including electrical extensions SATA

the leads from your ((motherboard to your hard drive)) make sure they have secure dust free connections and are not faulty or just replace them they might be faulty


make sure all leads that are attached to your drives dvd\cd have secure dust free connections and are not faulty even the electrical extensions


even something as small as an electrical fan and its lead can cause you problems

computers need all electrical power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error


make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free


restart your computer then reinstall it this should activate found new hardware wizard


or you might try


you will need to connect to another monitor or your television to your computer with the vga lead monitor connection

Sudden failure - working fine then next time switched on no apparent power (no indicator light on), no display


You could have a power supply problem in the LCD monitor.
First check the power lead, make sure it is firmly inserted into the mains socket and into the monitor.
Try inserting it into a different main socket that is operating, to see if the power indicator LED lights up.
If you have determined it is the LCD monitor is faulty, then it requires repairing.

I unplugged tv to move it across the room now it wont turn back on??


POE:
  1. Connect tv directly to socket without any powerboards and make sure the power cord is properly inserted (if it works than any powerboard you have been using is probably faulty)
  2. Try a different power cord
  3. See if socket is dead using another appliance. If another appliance works then the Tv is probably damaged (refer to warranty if applicable)
  4. if other appliances don't work in that socket check your fuse box.
  5. If fuse box is fine then try a different socket (if it works you may need to get an experienced person to fix the socket your trying to plug the tv into)

Laserjet 2100 Won't turn on!


Yep, the power cable can be faulty, test a different one on a different socket. Try also playing with the power connector on the printer.

If the power cable is fused, like for example in UK, then check the fuse.

If it still does not give any sign of life, then there is a fault on the power supply board, inside the printer, usually the power supply fuse. Part is about $45 refurbished/$55 original .

If the problem is not the fuse you will need to get a technician testing on board component, and probably replacing a faulty resistor or capacitor.

Power problem with nintendo wii


Hi,
Lets Hope So ?
Check the main fuse in the 3 Pin plug ( if UK )
replace if blown, also check the wires are tight to the plugs pins.
Is There any light Indication On The power Pack/Brick with These ?
Could be a faulty Power Pack.
Check the leads are firmly connected, quite easy to knock a cable out, with an accidental kick or push of the console et,c.

Colour change


Hi,
This sounds like an output cable fault.
Check that the cable connecting from the wii to tv is secure. ( not angled )
If you have different output/input sockets on the T/V ( scart et,c ) try a different socket.
Try the Wii on a different television Set.
Check that the mains plug ( if plugged into an extension Board ) Or double socket. Isn,t picking up electrical interference from another source. or loose wire on another plug, sharing the same sockets.
try moving the wii sensor bar, to a different location. ( above or below the T/V )
if you have a friend/relative who owns a wii, ask to borrow thier lead to try out. this is a process of elimination.
If none of these suggestions solves your problem, then you have a suspected console fault ( motherboard or graphics chip overheating problem )
Hope this information is useful for you.

No Indication...Dead Unit?


Firstly, try plugging the unit into another mains socket just to make sure it's not the socket that's faulty, or try another appliance in the socket you are using. Next, make sure the fuse in the plug hasn't blown. If you don't have a fuse tester, you can try the fuse in another similar appliance to see if it works. If it has blown and your spare lead is the same, there will be an internal problem. Inside the unit is an in-line 2 amp fuse. If this has blown you almost certainly have a power board problem. Always switch the mains off before plugging in or removing the mains lead from the rear of the unit. Back EMF can damage the appliance if you don't do this.
