C5707 available at?

No really available other than the C5707 or 2SC5707. Where are you located?

At this point you may be better off to replace the whole board, the four C5707 are transistors, not capacitor. You need to make sure that there are no cold solder joints around inverter transformers lead, check the tuning caps in the inverter output sections.

Replace the high voltage transformer. It is the ballast for the backlight.. If you could pinpoint the one that's overheating then that is the one that needs replacement. Much better if you will replace the four transformer...


Hope that answer your question..
Much appreciated if you could rate this help. thanks.

There are 4 c5707/5706 in the inverter transformer driving circuits, the cause of the problem was due to poor solder connection in the bias circuits of the transistors. Make sure to check that after you install the new transistors otherwise you will blowthem up. Common problem with this model. When the circuit drwas too much power from the power supply, it will shut itself off to ptotect itself.

Check the C5707 transistors especially its corrensponding hfe value. Replace caps

look at the 3 amp. fuse on the mainboard! By the way, you can buy very cheap USB light, wich are working with a small lighttube. Use the transistors of their generator!

You need transistors with hfe greater than 300. They are harder to get and you should use the producter`s original transistors 2sa5707.

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.

Your C5707 transistors in the monitor have failed. Suggest replacing all four with the Sanyo C5707 transistor. A common problem.

hi. i had the same problem and fixed it. the problem are the 4 transistors (C5707) one of more are shorted (Q739,Q740 and Q759, Q760). Also the fuse PF751 (3a) has to be replaced in most cases. In my case i replaced the fuse and 1 transistor (C5707)
