Question about Dell E172FP 17" LCD Flat Panel Monitor
I did do the C5707 transistor change, and I went from blinking LED to lights out after 2-3 sec.
It starts fine, but backlight disappear after 2-3 sec, I can see the contour of the moving self test picture.
To be honest, I only had 2 spare C5707 so it might be so that I have to replace the other pare as well, but they where not short circuited like, one of the transistors in the other pare.
You really need to replace all 4 and also the 2 FU9024 chips and examine all the solder in the inverter area. Also if you have the 2 lamp connector board with a chungwa LCD panel them your lower lamp is probably also bad. Check out www.lcdrepair.us for instructional videos on Dell models as well as repair kits and boards for that unit.
