Wierd inverter question

I got this decently good looking 17 inch lcd for free that had a bad inverter in it. I managed to get it going again using a couple of inverters from cold cathode kits that I have laying around. After running this screen for about 10 minutes, one of the two inverters fries on me, (it is a four tube LCD). I still get an even picture using the remaining inverter on the two bottom tubes. I was wondering if the additional load from the larger tubes was enough to burn the inverter out or maybe it is just the fact that it is an old inverter that has seen lots of use, and the additional load just made an already marginal part let go. I can get additional inverters cheap enough, but since I cant find out much about how they are rated, I would like to get some expert advice before spending some coin on something that could just be destined for failure anyway. Any input would be greatly appreciated.
 
You are probably lucky it worked long as it has. Not all inverters are the same you know.

What are the power requirements of your LCD? How much amperage do the cclf inverters put out? Don't know?
Then you are only guessing & hoping everything turns out alright.
 
Replace the CCFLs with LEDs. You'll never have to worry about them burning out, assuming you hook them up correctly (unlike this guy.
 
I have been using this monitor with the remaining inverter successfully for most of the day. I'm going to guess that it was just a marginal inverter with a little extra load that caused it to burn out on me. The remaining inverter running just the top two tubes seems to light the screen brightly and evenly enough that I probably won't mess with replacing the bad inverter for a while.
