Re: Dvr8-4000
May be you can show us the pictures of the board inside, especially the power supply board which more likely to be made by an OEM so even if you find the service manual for the unit, it probably will not have the power supply diagram.Never stop learning

Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?
Do you know how to find this connector please ? What is the exact name for find it ?

Greetings! I have this ERP650-PS atx power supply, it is a relatively simple psu, the primary has a driver IC that controls the two main mosfets (two 20n60S5), together with a Classic Standby circuit with a PWM IC (not a FET like the VIper22A) , relatively similar to the SDC606P.
The whole point is that I got this power supply years ago when I had no knowledge, apparently the PWM IC was burned because someone turned the power supply on with the switch at 110v in a 220v network (classic error). Important detail: the power supply at the time came without the primary capacitors.
