I've got this monitor that is having backlight issues. I have replaced all of the capacitors with low ESR caps purchased from right here at BadCaps.
That didn't solve the problem, so I ordered new CCFL bulbs from CCFLWarehouse and replaced them. The reason I did this was I found out through testing with some other backlights that I have free, from a 19" monitor, that they light up and stay lit just fine.
So, I have taken the old lights out and soldered the new ones into place. Here is where I think I did something wrong, though. Because I am still having the 2 seconds to black problem with the new bulbs.
I have taken them out and inspected and resoldered the wires, but still no luck. I am, admittedly inexperienced with soldering wires together. I am well practiced with circuit boards, though.
I suspect it is still my crappy solder job on the wires. So, my question to you guys is, how do I go about ensuring that my solder joints from the wire to the bulb is good? And, is it possible, that there is still something wrong with the board, and it is having trouble lighting the larger bulbs compared to the test bulbs from the 19" monitor?
