Burned up CCFL connector.......what could have caused this?

[Welchs101]

Hi,

I have this monitor.....symptoms: Turn it on and it comes on for about 2sec then shuts off.

I opened it up and found that one of the CCFL connectors "burned up". See enclosed pic.

Any ideas what could have caused this? Do you think if i just replace connector the monitor will work? Or do you think something more serious is wrong with the monitor?

They got hot and started arcing. That had to have made some racket and odor...... As for it working with just fixing the connector, try it and see.

Turns out the cause of this was a bad solder joint on the bulb itself. I took apart the monitor and found that the wire that "burnedup" had a bad solder connection to the bulb itself. I resoldered the connection, replaced the connectors and all is good now.

Note: This was on a monitor F90JS.

Thanks.
