Re: Benq ET-005-N No backlight



hello, the fuse you mentioned is fine, if i will try that test with the 10k resistor and if is still not working there is nothing else to try?

i will try to put the resistor and see if i managed anything...

thanks a lot for your help!...

Re: Benq ET-005-N No backlight



there are 6 pin notations and 8 wires so looking at the back of the board starting with the upper pin (blue wire) that is near the hole with the ground of the board the voltages are as follows:
- 3.27
- 0.03
- 0.88
- 3.3
- 0
- 0
- 5.1
- 5.1

Thank you very much for your help. another thing that i should say that the monitor when stooped working i replaced the caps, they were bulged, i don't know if they are any good brand and they were not tested with an ESR mete...

Re: Benq ET-005-N No backlight



on d08 with red probe on the middle pin and black on the other 2 pins is 14.9 V
on d805 same probe arrangement is 5.1

part no: OZ9938GN...

Hello,

I have an Benq ET-005-N with backlight problems, the CCFL lamps are not starting at all but i test them and are fine, I know the monitor works because I used another board to fire up the CCFL lamps and once the lamps are on you can see the image on the screen, the caps are replaced are not bulging and tested for capacitance, the transformers have the same resistence both of them (0.63K) so either are both damaged or is the right reading. Any advice will be more than helpfull!
Thank you very much!...
