Re: Samsung UE40C6000RWXXN clicking power board issue
I bought another powersupply from aliexpress. Well... It doesn't make the click sound anymore. But now I got no picture only sound
I do got backlight and I don't see something when I shine a flashlight on it.
Any tips to investigate?...Leave a comment:

Oh ^^
Well , I soldered my fuse. And I thought let's just give a try Plenty of fuses in the house. But I plugged in and it blew my fuse holder of FS801S out of my soldering. But I think it's not broken. So little bit scared to plug it in again =/...

Arghhh.. I missed it completely because I wanted to order before the shop closed -.-. I got a slow blow...
I think I just order myself a new board found one on aliexpress for 25 dollar that's the same price I spend on the components already because I bought them x25
I'm just to noobish to fix this myself I guess. So I better spare you guys time But I would like to thank all of you for the incredible help and fast responses!...

Just the fuse. Are the mosfets broken according to my measurements?...Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
I have new fuses. They are bigger then the original because otherwise I had to wait too long. But the value is the same 2A 250V. So I can make them fit.
Should I investigate something more before I put the power on again?...Leave a comment:

1.5 ohm from gate to drain and 2.2 ohm from source to drain for QM803
0.9 ohm from gate to drain and 2.2 ohm from source to drain for QM802...Last edited by sepper; 07-12-2017, 02:32 PM.Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
Ok, I have to order one
Hopefully it's here tomorrow but It's late so I guess it will be here on friday.
Sorry for letting you guys search so deep in the diagram because of a stupid fuse mistake. I thought it was acting as a diode. Learned a lot already. I hope the issue will be fixed by the replacing the fuse. Keep you guys posted. And thanks a 1000x times!...Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
Ok, I think we have a winner... I unsoldered it. Gives OL. So its 100% broken.
Can I just bridge it for a quick test or is this not done?...Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
Yes. The fuses are ok.
FB801S 0.5 ohm
FM801s 1.2k ohm in one direction and other direction open circuit... So it's acting like a diode as I already asked. It's not really saying something about that on the diagram or do I need to unsolder it....Last edited by sepper; 07-12-2017, 01:06 PM.Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
FM801S is this a diode fuse? Because one side is 1.2k ohm other side is OL.
Other fuse is Ok....Leave a comment:

13v without switching
I measure a stable 5.8v over CM803 but on CM802 I measure 0.8v. Is this weird?...Last edited by sepper; 07-12-2017, 11:15 AM.Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
I unsoldered RM814 and it was 910k all the other values where ok too on circuit. So no need to unsolder them I guess?...Leave a comment:

Re: Samsung UE40C6000RWXXN clicking power board issue
I only get 500k Ohm on my RM814 RM815 and RM817 should I get 1M instead?
RM816 - 950k ohm
RM818 - 17.8k ohm
RM825 - 17.9k ohm...Leave a comment:
