My KDS K-22MDWB monitor went belly up last week. It wasn't a big surprise, for the last month when it came out of standby the lower part of the screen had a pinkish glow. When it started 'Two Seconds to Black', it was time to swap in another monitor.
Opening up the KDS wasn't too hard, getting into the LCD panel was a different matter but eventually I succeeded. Sure enough, one of the CCFLs has an unhealthy pink glow, the other three are pure white. After some measurements it seems the CCFLs are 2.2 mm in diameter and 475 mm long. CCFLwarehouse has them at $9.95 each ($8.00 if I order through eBay). Of course, I'm going to need kapton tape, o-rings, wire, etc. The problem is while my mechanical skills are adequate at the macro level, they are lacking at this level. I'd have to order at least 6 CCFLs to have a chance of getting 4 in. Or I could have them rebuild the assemblies; that would cost about $90, probably more than a 22" monitor is worth; certainly when I can buy a new 22" wide screen monitor for $129.
The LCD panel has the following information: Proview Technology Company Limited. Model PV220WLCM Product # M220Z1-P01. Googling that information led me to the information that M220Z1-P01 is a Chi Mei (AKA CMO) part number, and the panel is also used in an Element TV. Further digging found this auction on eBay, which would be an acceptable solution. The picture appears to match the CCFL assemblies in the KDS monitor. I have contacted the seller for information on the dimensions of the assemblies; he has not responded. Not his guarantee isn't very good - the CCFLs are guaranteed to work in any monitor they work in.
Questions: From the picture below, is this a CMO panel? What panel is used in the HP W22 monitor?
Details not obvious in the pictures: The channel is 19.25" long, 9/16" wide, and 5/16 high.
