Well, so the story goes, I had problems with this monitor about a year ago where it would come on and work sometimes, but other times the screen would be blank. I'd have to turn it on and off numerous times to get it to show the display. Well, after some interweb searching, I found out that this monitor has issues with Caps going bad. So, I opened it up and found there were indeed leaking caps. So, after research, I ordered a kit that contained all 9 caps, a very tini tiny thing (don't know what it's called, forgive me) and 2 transistors/mosfets (the 2 things just to the right of the 2 big transformer looking things (can you tell I don't know what all these things are called?!). When I received that kit, I only replaced the caps that were bulging. This fixed my issue.
Now, a little over a year later, the monitor just went out. When I turn it on, I get the 2 seconds to black deal that I've read about recently. So, I dug out the rest of the caps from that kit I bought a year ago and replaced the remaining caps, even though they weren't bulging (but I've read that it doesnt have to bulge to be bad). Still get the same issue.
So, i did a little more research and came across a thread about this same monitor and to check if the CCFLs were bad, they hooked up some from another monitor to see which was bad. Well, I did that last night. I took a Dell 17 monitor from work and opened it up to expose the leads for the CCFLs.
I hooked them both up to my monitor (externally, didnt want to take apart my screen that deep until I knew if one of them was bad or not) and they both came on and stayed on. No 2 seconds to black.
So, I hooked 1 of the CCFLs from my monitor up and 1 from the Dell up. Same results. They both stayed on until the monitor was turned off manually.
So, I hooked the other CCFL from my monitor and kept the Dell CCFL hooked up. Same result! I was HOPING that one or the other configuration would yield a different result, but such wasn't the case.
What else would y'all suggest? I initially thought that since my monitor kept the 2 CCFLs from the Dell lit without going out, that 1 of the 2 bulbs or the associated wiring was the problem, but now I'm just stumped!
For what it's worth, I CAN see a picture on the monitor when the CCFLs go out but using a bright light shining on the screen.
Any direction on this matter would be GREATLY appreciated!
I did take some pictures, but they were too large for the on-site uploader, so i put them in Photobucket. Here is the link to the album:
