HI, is my first message! however I wanted to ask if anyone knows how to control the backlight of 700tsv .. I made a small change with a potentiometer, but are not very convinced of my work ..

you can't.

I have really made the change, regulated by a potentiometer .. soon put a fotosensore for automatic luminance

is possible by changing the card (only) of the screen .. add photos of the amendment ..

cut where the black mark

4th, check that there is more driving .. from condesa jumpered resistance SMD

**Alex88** · 09-23-2008, 03:17 PM

5th, linked by a potentiometer 680ohm or less between the 2nd leg of the aid to the bridge ..

resistance 0ohm = max brightness
resistance 680ohm = off brightness

WARNING! The runway is to cut power, is covered by the power of CCFL, and then generates HEAT!

The ideal would be a transistor stabilized!
