I HAVE A BALANCE COMPUTER AND ITS A FEW YEARS OLD

Try the following troubleshooting:

1.What you need to do is the following, there is something called a power discharge, what you need to do is the following:
1. Remove the AC Adapter/Charger
2. Remove the Battery
3. Hold down the power button for
1 minute
4. Connect everything and try start
-ing it back up
Basically you are draining all the
remaining static Off the Motherboards Capacitors.

If this does not work

2. Check on an external monitor, If there is no display your Graphics Card could be faulty,
If there is display the LCD Panel could be faulty.

3. Do you hear any beeps, if there is 1 long and 2 short beeps it is 100% the graphics card is faulty.

Hope you find this helpful
