 Posted: Thu Jul 02, 2009 11:14 pm Post subject: Pico Fuse |
 |
|
Hey I have got the same problem with my HP 1530.
I think i have located the pico fuse. Its black has no markings?. Anways it has a code next to it FP751. What does this mean?.
The tech shop has pico fuse with the code FP2 which is 2A and also FP750 which is 750mA. Which one do i need? A 2A? Does the code by the fuse matter?.
All help will be appreciated.
Thanks. |

HI Guys,
I got the same trouble on hp 1530 too, i found the back light came out for a second and turn off itself and no back light lit out any more. However, I could see the shadow of message { NO CABLE CONNECTED } appear.
So could any one tell me to identified and replace the bad ICs on Board....
Thanks and Appreciate for all help.
Rath, |

You all may want to check out Dell FP152 / FP172 series posts, here and elsewhere. Bad joints on transformers / shorted transistors & FETs along with the pico fuse already mentioned.

Hi i have the same problem as some.
HP 1530; Model: PE1236
When i turn the monitor on green light comes on and when screen lights up it turns off and it does that on and on. I never see anything on the screen. I checked fuse and its good. Changed 4 Brown Capacitators and didnt help.
Here is a picture of the circuit, if anyone can help me out.] |
