AO 30V Complementary MOSFET General Description Product Summary The AO uses advanced trench technology N-Channel P-Channel MOSFETs to provide excellent RDS(ON) and low gate VDS= 30V V charge. N-Channel：VDS=30V ID=6A RDS(ON) ＜ 30mΩ (VGS = 10V) RDS(ON) ＜ 42mΩ. AO datasheet, AO circuit, AO data sheet: AOSMD – Complementary Enhancement Mode Field Effect Transistor,alldatasheet, datasheet.

I know this is an old thread but I figured since there is good advice here on the P I should see if my problem will add to it. I am not an electronics wiz, for this issue I am more of a one trick poney.

I thought the 2nd number was the part number. Page 1 of 2. I have fixed a lot of monitors by replacing the caps on the PS card but this will be my first with processor card issues. Should ALL of the inputs on the primary side be shorted?
Using what you guys said i started probing around. Can you tell from the data sheet if D2 and D1 are shorted? I see no obvious issues visually. I did reflow the transformer connections. If that does not work I will ask if anyone wants a monitor for parts or repair as I will be outa my leage. Originally Posted by Welchs thanks!!!!!!

I have included a pic of the chip. Originally Posted by Welchs Right now, when i power it up If those voltages are not present, check the voltage across the large cap – it should be 1. SO this leads me to ask the question Datashete this one has the good brand of Samxon for all but the big guy and that is a KM M but they rarly go bad from what I know.
You really think the burnt spots are just due to bad solder joints? Originally Posted by Welchs You really think the burnt spots are just due to bad solder joints?

I checked between gate and drain, source and drain ALL of the inputs on the primary side be shorted? However with the ai4606 signal from my notebook PC the screen is solid bright white for as long as I care to look at it.

I opened it up and found two burned areas on the power supply board see enclosed pic.

I looked into the fuse and connector advise and could not find any issues. Originally Posted by Welchs a friend brought it to me ALL 6 pins are shorted I replaced all the caps on the board with new ones I found one cap “near” the big filter cap which was “bad”.
Have you seen this before? The rest of the buttons produce no set up or adjustment windows and I can see no video from my PC at all.
It is usually capacitively dataasheet. So i guess the chips are ok. One end to the circuit while the other to the transformer pin.
Right now, when i power it up So i guess its ok. I started with the voltage across the big filter ao4660 Originally Posted by Welchs SO this leads me to ask the question I did attach photos of the front and back of it.
