[1supertech]

Hello folks
I made this handy tool to test if monitor have bad ccfl out of
good ccfl bulbs I incased bulbs in a plastic clear tubing 1/2 inch in diameter. from HD, two PVC end caps 1 drilled fro wires. works great.

Thought I would share this :-)

Re: CCFL test Tube

We have the same thing but without the plastic tube, it's an important tool and we aren't so rough that the lamps get broken.

The complimentary tool is an inverter with a pair of DC wires for 12V that will turn on a set of lamps. that way you can unplug the lamps and plug them into the 'test inverter' and light the screen while turning on the monitor to send video data to the TFT.

We've found that it's important to do both tests, we want to make sure the LCD is worth the labour of installing new lamps before we proceed, too many times we've determined the lamps are bad, replaced them only to find that the TFT also has lines or dots or other problems, then we are left with wasted time, energy and used lamps that we can't bill for.

I guess I am being over cautious you never know, but anyway I thought I would share a good idea to protect bulbs.

What I do Is buy non working monitors if I find that the CCFL bulbs are bad I use it for parts. Not cost effective to by bulbs when I only sell monitors for 35.00 to 40.00 dollars
