Having problems with your HP Compaq Presario C306US Notebook ?

No video on Compaq presario C306

\015 I can barely see screen , if I use a flash light. Have replaced the inverter and the backlight. Still the same problem. Any help??\015

Answers :

When the backlight is black ie. the CCFL lamp is not illuminated that means the CCFL lamp is dead (it is basically a very small fluro tube) or the inverter is faulty and it is unable to supply high voltage to the CCFL lamp.
\015\012make sure the inverter is firmly seated and connected.
\015\012Check the wires to the CCFL lamp, there is a couple of wires from the inverter to each end of the CCFL tube.
\015\012Check the CCFL lamp voltage on the inverter it should be 100 - 150 volts.
