Manson NP-9613

Re: Manson NP-9613

Could it be this one is the cause ? When I tested ESR=1.5 Ohm Caps = 5400uF, suppose to be 4700uF

Re: Manson NP-9613

I have replaced both on the blue box, no luck yet ?

Re: Manson NP-9613

I can spot CN4, but which one is Q7 ?
I saw it, it's blown isn't ? after zoom ...

Is that not Q7 marked on the board? so the transistor next to CN4 beside Q7

Re: Manson NP-9613

the relay : ,
I got 277 ohm on the coil

Re: Manson NP-9613

I've replaced both 2N3904 and TL431, no luck, yet,
could it be a relay issue ? thanks

Re: Manson NP-9613

Right under that cap. You are on the left of it.

I can't get it, the one on the blue box I'd made ?

Re: Manson NP-9613

Have a look on photo please, are these, do you guys mean ?
I'll check, and return to you guys...thanks

Re: Manson NP-9613

The transistor next to CN4 also looks bad, compare that transistor to Q7 and you can see Q7 has the spot along the molding line which is normal but the transistor next to it looks like it is damaged at that point

Re: Manson NP-9613

looks like there is a bad transistor next where VR8 is written on the board?

VR8, which transistor ?
Do you mean U2 ? that's TL431

Re: Manson NP-9613

We need pics to see what you got!
Is it hitting a cc cutoff or what are the testing conditions?

cc cutoff ?
I got one burn zener diode and replaced it,
could it be TL431 or relay is broken ?

Thanks

Dear Members,
I have an issue with Manson NP-9613,
Everytime the voltage hit 19V, the relay is switching and voltage is going down,
What is the issue ?

Thanks
