Hello all, long time no see :-)
Well, I'm a retro computer collector, and I like to make my computers functional and shine for museum exhibitions.
Here I have a nice Toshiba T6400DXC portable computer with a broken CCFL tube on LCD screen. LCD is SHARP LQ10D013 with two unusual large diameter CCFL tubes (see pic). Tube lenght is 264mm, and diameter is 12mm! Each tube has 4 terminals, two from each side of tube, 8 wires total for 2 CCFL tubes. One tube is broken, symptoms are as expected - backlite turns on for 1 second and then goes off.
My questions:
1. What kind of CCFL tube is that?? Why it has two terminals from each side?
2. Does this CCFL works like two standard CCFL's?
3. Can I use 2 standard 260mm x 2mm CCFL tubes instead broken one? How to wire it to existing four terminals??
4. What about using dummy resistor load to fool inverter and go with only one CCFL lamp? How to connect a resistor(s) to these four wires and what resistance and W to use because of this unusual CCFL design??
See detailed pics.
Thanks in advance!
Best regards,
Suad
