I'm in need of 2 CCFL tubes for a 15" LCD monitor. I'm not sure where to
start looking.

We have several IBM ThinkPad T30's at work that have
bad backlights. IBM wants $595 to replace the whole lid
unit. They will sell the backlight, but don't offer the
CCFT as a FRU. The units work well with a CRT, and you
can see the Desktop with a flashlight, but right now
these are paperweights.

I would like to replace the CCFT and inverter and
repair these units. Is there some hidden "catch" to
this? Our local depot doesn't do it. I have the HMM
which describes how to disassemble the display, and I
am IBM certified and able to do the work, solder, etc.

I also just had a HP VZ5000 through with the same
problem. I was unable to open the display to
investigate-prudently put it back together rather than
break it. HP wants....$700 to fix the unit, not to
mention reducing the young lady owner almost to tears
during an hour of phone transfers and changed
stories/prices.

Any comments?

While I haven't worked on those specific machines, I have replaced a few
backlights and usually it's not too tricky provided you keep track of
where everything goes, digital camera is great for this. Often you have
to bend a bunch of little tabs to remove the metal frame from around the
display panel and sometimes there's a bunch of screws and some tape
holding things together but the tube is normally not too hard to find
along one edge of the panel.

Hi...

I'm long retired, and waaaay behind... but somewhere recently I heard
or read that Mouser Electronics, in Texas, USA had a vast assortment
of CCFL tubes...

Take care.

Have done several IBM, Dell, etc notebooks and HP NBs and desk-tops.
In general, try replacing the tube(s) first; only if a new tube doesn't
work should you replace the inverter. Also in general, you will need
patience and a good loupe to identify how things are assembled. Double
sided tape and hot melt glue (or something similar...I've heard it
called "Panda snot") are very popular for assembling displays; there
are rarely more than 2 or 4 screws anywhere. I've also found that any
CCFL tube that physically fits will usually work just fine...an "exact"
replacement is not necessary. However, if you don't find an exact
replacement tube, the display may end up with a slight overall color
cast.

I'll add that before you go through the trouble to replace the tube,
wire up the new one to the inverter and turn it on to make sure it
lights, no point in taking the effort to dissasemble the display if it's
not the problem.

If you can find one with a 6500K color temperature then the color should
be fine.
