Hi,
This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.
Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working ccfl lamp on cn304 lamp connector. Now the monitor is back to working condition with the used working ccfl lamp still hanging outside the power board as i have not opened the delicate lcd panel yet. I am afraid i might damage the other upper working ccfl lamp.
My question here is why the monitor can't display when there is only 3 working ccfl lamps (1 ccfl lamp is tested burned)? Is there any hack that we can do to sort of cheat the monitor to use only 3 ccfl lamps instead of the normal 4 lamps. I am attaching picture of the power board and the monitor working after i temporary attached a good ccfl lamp on cn304 lamp connector.
Any help and kind comments will be much appreciated.
