iiyama ProLite E2407HDSV

Dear friends,
I have this monitor, iiyama ProLite E2407HDSV
It came on but nothing on the screen, I have checked all the caps on the both inverter and psu board and the entire caps look ok no bulging or leaking as far as I can see.

Thanks for the excellent pictures. They make it much easier to help.

Red circles in lower left: With monitor plugged in, CAREFULLY!! measure the DC voltage between the two points. Should be about 1.4 times your AC line voltage.

Yellow circle in upper left. Ground point for following tests. Measure the DC voltage on the points circled in blue. Also note their is one more half way across the board to the right.

Thank you Plain Bill, I am back to ground zero, before I could do the testing the fuse has blown, I replace it and gone again so by the troubleshooting I found that the power mosfet 2764I (Q801) has shorts between all the legs, I have google it but I did not find it. Please is there an equivalent part to use.

It's an AP2764I-A The datasheet is available, and the parts are available here.

PlainBill I did not see the datasheet for the FET and please can I was get this bridge rectifier (GBU 4KL) from the same campany?

I have no idea.
<Rant mode ON> I am a human being. I do not carry the inventory records of every distributor in my head, nor am I a mind reader. Heck, I don't even know where in the world you are! <Rant mode OFF>

I took the part number you gave, figured that it was a partial number, and was able to determine the full part number. Googleing the full part number found a company that claimed to have some in stock. It is up to you to determine if they will sell in acceptable quantities and what other items they have in inventory.

Neither the power FET nor the bridge rectifier are unusual components. With the datasheet you should be able to locate a suitable replacement. No, I can't help you with that, I don't know which parameters are critical.

Please I am very sorry if I have upset you with my questions, please forgive me. I always look upon you as one of my masters when it comes to repairs.
