View Full Version : Dying Monitor
My desktop monitor is getting dimmer and bluish. CCFL dying or inverter? Is it worth fixing? Has anyone tried? I found this site with info: http://www.lcdparts.net/DI3D.aspx

I bought an inverter from them to fix a dead Planar LCD screen that I paid a lot for years ago. It worked fine for two more months, then quit again, so I gave up on it and bought a reconditioned Dell monitor (which I'm very happy with). Your problem sounds more like fading CCFLs, though, although the ones I've seen fail have turned more more pinkish than bluish.

My desktop monitor is getting dimmer and bluish....
That sort of thing happens as you grow older. Other people start to seem smarter and appear to move and talk faster, too. It's best you just accept it as a natural process of an aging brain. I strongly suggest reading (while you still can) the book to which I've linked below. It will help you understand what's happening to you as you gradually lose your senses. There there... There there....

I have no idea what those symptoms mean but I opened up a monitor that died on me and found a couple of bulging caps and a resistor that looked burned out. I replaced the components and was very pleasantly surprised to see it come back to live.
I have since learned that bad caps are a common cause of death with monitors.
I don't know if bad caps would cause a dim blue screen, but the capacitors are cheap and not too hard to replace.
Caps are cheap. The only thing cheaper is tightening the screws on the monitor connector, which completely solved my problem. A quick Google search listed several "bad cable" solutions and the rest was easy.
Man, how I wish I could go back in time and not post this ridiculous question. Makes me think ElectricEye is on to something. Now why did I come in this Forum? What did I need? Did I forget to remember or remember to forget?
At least I discovered the problem before I tore down my perfectly functioning monitor. :)

I would not have found that problem in a million years! I would have "assumed" the monitor connection was good!
But that goes back to troubleshooting 101, first things to check... Is it plugged in? Do you have power? ....
And now is the video connector securely connected? :smile:
What type of connector? VGA? DVI?
I have a monitor that failed after a power hit last year. It shows a display for a sec when I power it on or connect and disconnect the input. Then it goes black. I bought another 23" LED monitor for under $200. In my never humble opinion fixing the 23" lcd isn't worth it. No way am I going to spend ~$70 for an inverter to "see if it fixes it". If someone in the Chicago area wants to try to fix my bad monitor I still have it. :smile: Sorry but I have no interest in shipping it.

Anyone who doesn't tighten his monitor connector screws all the way has my total sympathy and understanding. The LCD manufacturers have a way of tucking the mating sockets in such confined locations that it's almost impossible to get a purchase on the screws with your fingers, and who has time to hunt down a screwdriver in such situations?

I'm sorry the solution to your problem was so simple. It was the perfect opportunity for an upgrade :D
