Re: MOSFET question

Thank you! Already done and the resistance seem compatible while on-circuit (around 2,8kOhm). I wanted a confirmation before starting to unsolder (and search) a 2,5x2mm ic...

Re: MOSFET question

Thanks to all for the replies! the NPN seem ok, and the pin 4-6 of the mosfet aren't shorted. Sorry for the unclear question! I simply don't understand why using a mosfet in this case (without bothering to put up the entire schematic... i'm stupid )...
To semplify: I measured the voltages of all the pins and i have 0v on the gate and 5v on the source... so i have a gate-source voltage > 1,5V... why i don't have 5v on the drain? bad mosfet?
I will create a thread on the TV section when i can't diagnose anything else, just started yesterday...

Hi all! I recently began troubleshooting a TV (SHARP LC-32GD8E) and i think i found the cause of the trouble, there is a MOSFET (SSM6J51TU) that i think is not working but having very little knowledge about mosfet i thought to ask: the configuration is in the attached image (from the service manual of the TV) and the pins 1-2-5-6 are shorted (reading 0v), the pin 3 read 0v and the pin 4 read 5V... why using this configuration? what is the reason? protection of the 5v bus? I'm right in my assumption of a bad MOSFET? (no output in pin 1-2-5-6)

PS: Sorry for the horrible articulation...

Hi all! I'm a Italian computer engineering student, so if i'm writing rubbish english you know why. I have registered to, like almost all the others, abuse the minds of the guys here!
