Re: CM V700 no +5vsb, ICE2QR4765 low VCC in... Need guidance please...
Sorry for late reply.. been busy for the last few days...
@Per Hansson.. Thank you for your concern, I already make sure to discharge the cap before I touch the board again.
Well.. today I have some free time, and since the new goal was looking that 6w pull... I decided to "cut" all the high voltage DC rail by pulling the component one by one..
As @stj suggested... I pulled the bulk cap... but still the same..
I started pull the resistor that...

Re: CM V700 no +5vsb, ICE2QR4765 low VCC in... Need guidance please...
@momaka
Unfortunately I don't have inductance meter, but
I will try your idea of injecting VCC voltage on ICE2QR4765 and take another look on 5vsb circuit again..
Well the reason for me to fix it, that this PSU will go to my son PC as he want to add a dedicated VGA card...and the one he have now just old non branded PSU
@stj
I have pull the transformer and measure the transformer, As I recall there is not any leakage between winding. But, I will try to pull everything...

CM V700 no +5vsb, ICE2QR4765 low VCC in... Need guidance please...
Hello...
I got my self a dead CM V700 PSU, with nothing on +5vsb
I have tried to fix it for the past 2 week, and I'm stuck... so i guess i post it here to get some pointer before i scrap it..
As you can see in photo, the psu still pretty clean, no visible damage or bulging cap.. when i got it, it still has CM seal on it
The +5vsb system use ICE2QR4765, I have trace and measure the voltage on ICE2QR4765 and the only voltage reading i got is in VCC 4.8v, Drain 310v and FB 3v.
I have read the datasheet and and still can not...

Troubleshoting Seasonic KM3 based PSU, Advise please
Hello..
I have CM V series that wont turn on...
No voltage on +5VSB and PS_OM pin...
The board layout exactly like in this thread
[url]https://www.badcaps.net/forum/showthread.php?p=908291[/url]
after reading the thread above... I measure the voltage on those mosfet ( U3 and U4 )
U4
Drain pin : 200v, Gate 2,72V and nothing on S pin (0v).
U3
Drain pin : 170v, Gate 2,72V and nothing on S pin (0v).
I assumes the voltage on Gate pin should turn the mosfet ON... (please correct me if i'm wrong)...

Samsung LA32D40s HV320WXC-200_x-PCB-X0.0 blank,backlight OK..
Hello, I have Samsung LA32D40s lcd tv with blank screen, but backlight and sound are ON. This TV have been dead before due to thunderstruck, and the repair shop replaced the lcd panel but after some time this TV malfunction again. The repair shop said that the lcd panel dead again.
Turn out, the repair shop replace the lcd panel with another compatible panel ( glass only, not include with housing and backlight unit ). The model on tcon board says HV320WXC-200_x-PCB-X0.0
I have tried to probe the voltage on TCon board, but I dont have any reference what normal voltage...

Re: Asrock H87M-ITX power on and off, need advice please..
@mon2
sorry for late reply,
the coil resistance seems normal as I remember, but I will definitely recheck all the cap..
as the switch, no its not external switch, when powered on with shorting power pin, it will turn off an on by it self... including power led.... its just on and off
I will try again as soon as I have time, and will report back...
Thank you
@RadoLouson

Asrock H87M-ITX power on and off, need advice please..
Hi members...
I have Asrock H87M-Itx that sometimes ago dead due to bad bios, and thankfully one of good Badcaps member help me with the bios file.
It have been working flawlessly for a few days, but suddenly this morning, the motherboard just wont turn on.
If I pressed the power button, the power led comes on for one second and turn off. I check the psu_on pin while attach on motherboard, the voltage fluctuates, like it wont latch.. and I have swap 3 different good known PSU.
So its like being switch on an off repeatedly...
