You can still ahev the backlight power supply problem because the 5vdc powwer supply for the logic board may be working but not the 12vdc section, or problem in the inverter circuits, lamps, etc.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

RVS10 only show blue light. not starting


the blue light on means the light is getting power
test your PSU power supply unit if the psu units fan is not working the psu is faulty
check the leads from motherboard to hard drive EIDE/SATA make sure connections are secure and dust free
if its a flat 40 pin ribbon type this will be the first to fail
also make sure your cd/dvd drives are working even something as small as a faulty electrical fan lead can cause this problem
make sure your ram modules and cmos battery are securely seated with nod dust in the sockets although on some motherboards th cmos battery is soldered in
a computer needs power and data to travel through every working device and to have an end point to work
hope this helps you

If pluged into light not powering at all


Firstly insert the battery. When you plug the PSU into the machine does a charging light turn on? If not then check the fuse in the mains plug as it may have blown. If the fuse is OK then you may have a defective PSU, although the motherboard could also be defective. Try a new PSU to determine if which component is faulty. <br /> Now remove the battery and insert the PSU. Will the machine turn on or do any power lights illuminate? If power lights illuminate and the machine will not turn on then I would suggest the motherboard is at fault. If the machine turns on briefly the turns off before displaying the splash screen then I would suggest the RAM, CPU or motherboard is at fault.<br /> If the unit works without the battery installed then it is probably a battery problem, although it is possible the charging circuit on the motherboard is fried.<br /> Hope this helps,<br /> www.PuterCare.com<br />

Power supply unit gets power as light on the back shows but pc wont turn on. Have tried differnt PSU and pc turned on but have had unit checked and they said the PSU is working fine. Cant fit standard PSU...


Try this to get it at-least back on with your PSU that fits in the case. open up your computer case, locate your power supply. With the AC cord still plugged in , unplugged the connectors to your motherboard from the PSU and wait about 10secs. Then replugged them in. This should power on your PC.
Also, You wanna check around where the PSU connects to the motherboard and make sure there is no damage. No burning,Discoloration anything that could be potential damage.
Hope this works atleast to get the PC booting up.

Why when i switch my hp 6720s on does the battery light flash amber then goes white nd the laptop switches off? all in 5 seconds


It sounds as if the battery is too low to power the unit on.
Firstly insert the battery. When you plug the PSU into the machine does a charging light turn on? If not then check the fuse in the mains plug as it may have blown. If the fuse is OK then you may have a defective PSU, although the motherboard could also be defective. Try a new PSU to determine if which component is faulty.
Now remove the battery and insert the PSU. Will the machine turn on or do any power lights illuminate? If power lights illuminate and the machine will not turn on then I would suggest the motherboard is at fault. If the machine turns on briefly the turns off before displaying the splash screen then I would suggest the RAM, CPU or motherboard is at fault.
If the unit works without the battery installed then it is probably a battery problem, although it is possible the charging circuit n the motherboard is fried.

Can not live, although PSU existing electrical currents


Your PSU is not working properly because it shares the current in a minor way, it is not providing power as different components requires.

Fujitsu Siemens Scaleo 600. No power to processor.


Probably a PSU failure, although it could just be your power switch. Try shorting the power switch connections on the motherboard, if that doesn't work, replace the PSU with a standard ATX PSU. They're relatively cheap.

Upgrading power supply


The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).
