Are you sure the fuse is ok?
You measure AC, right?Comment

i did a continuity test on it, i took the fuse out of its holderComment

Check input voltage directly at the connector. Sure it's there?Comment

Re: usp440m-42lp psu
Nothing. Extension lead is fineComment

Re: usp440m-42lp psu
Well, then the problem is somewhere else. I don't have the TV in front of me, just the board. Check the connector/cable etc.Comment

Re: usp440m-42lp psu
That's very strange. Is your multimeter working? What if you measure the AC directly at the wall outlet?Comment

Re: usp440m-42lp psu
There is also an EMI filter directly connected to the AC inlet of the TV. Maybe it's faulty. You could measure the output voltage at its terminals.Attached FilesComment

Hi guys
I need one of these MP2329CGG for a repair job. It's a 24V 6.5A buck converter. But I have not been able to find a supplier who has that component.
Actually I would buy a few as I always think if I found one faulty already I will probably find more in the future
I had one supplier on Aliexpress who gave me a price $2 each, but I have been waiting some days since I asked for shipping price and they don't reply
Does anyone know where I can buy that part in small quantity (let's say 5 of them), or any equivalent I could use? it supplies the Standby... -
Hello, although I've never been formally taught soldering techniques, etc... I've not really run into too much trouble soldering, with the exception of this job...
I've got a supposed blown transistor on my fuel pump on my car and I'm trying to replace it. It's a gel encased circuit booard with very fine connections. Please see photo uploaded.
I've cleaned up the area that I'm working on with alcohol scraped off the wires, etc..
I cannot get any solder to now stick any of the connections, I've used various grades of solder and flux combination, nothing... -
Help please with identification of few components for troubleshooting (Solar Water Fountain circuit)Need some help please with a few components on this small board so that I can troubleshoot the circuit.
The PCB is a Single sided board fairly simple circuitry has a +ve and -ve Solar cell power input, a 7.4v 1500mAh (dual 18630 cell) power in which the Solar panel charges the cells, and lastly the Output goes to a DC connector...
J1 is actually 1P1T Switch (in ON position completes Battery cell circuit
J2 - to DC Output
J3 is Battery cell connector
however I am struggling to identify if:
Y1 (SOT-23) are NPN Transistors, MOSFET's or 11v Zener's.... -
Hello friends. I have been struggling with this device for several months. The problem is that the laptop is 6th generation and every BIOS I find is 7th generation. In the BIOS settings, it says Kaby Lake in the integrated graphics. The graphics drivers are not installed properly in Windows either. I would be grateful if any of my friends could help me finish this laptop.
Model : Alienware 17 R4 (6th gen)
Motherboard : LA-D753P rev 1.0(A00)

I have a very strange issue here. Customer was using Mac one day and stopped working when they went to use it the next day. I plugged it into my amp meter and I got 5v at 0.10amp.
Checked all rails:
PPBUS_AON: 12,3 V
PP3V8: 3.79v
PP3v3_AON: 3.29v
PPDCIN_AON_CHGR_R: 5 V
The very strange part of the issue is that I left the Mac on one side for a day, came back to it and reconnected everything. Connected the DFU cable to a WS machine and connected the charger. The Mac then booted to the login screen? I then logged in and because I was after...
