I have a Acer 22" gotten from a my brother. It has a issue that i am unsure of the diagnosis on what it may be i have done alot of searching on the internet. as well as attempted to use the service manual to diagnose this issue. However the online one seems to be missing some info. from what i have read it seems to either be the power supply power inverter or one of the logic boards any help that you could give in helping me diagnose which it is would be greatly appreciated. I have of course tested different cables sockets computers all that just to make sure it wasnt an outside issue thanks

If you press the power button and nothing comes on at all then something isn't providing power to the laptop as it should and you may likely need to replace the battery or the power cord.
Find a replacement battery. Change your battery with a new one then plug it up and turn on to see if this works.
If replacing the battery doesn't work then replace the power cord and trying turning it on again. If this doesn't work either, you have a more serious issue going on.
Not too long ago, I was on vacation, my laptop had been working fine until suddenly it wouldn't come on at all. I went into the office to grab a new battery and power cord. (I work on computers so I had spare parts in my office/Tech Room.)
I got home and replaced the battery then tried to turn it on using the old power cord...didn't work. This was a brand new battery so now I knew that I could rule out the battery as the issue...the only two things left to troubleshoot were the power cord and the laptop itself.
I put my old battery back in the laptop then tried to turn it on using a different power cord and it worked. I didn't need to replace my battery or laptop. The power cord had failed.
I hope that your issue is as simple as this solution. Try confirming whether your battery and power cord are still working...you may just need to replace one or the other.
Thanks for using Fixya.

R1 will be blown, replace it with a 10 ohm resistor. Also replace C6 and C22 with 220uf 25v Capacitors.

this should be easy...go to your desktop...right click on it and choose "personalize" it will open up a window. on the bottom it will say display settings...click on it...at the top right it should say "identify monitors" click on that...if that dosent work.click on the monitor that has a 2 on it and it will ask you if you want to add a monitor...it should work
if not, post a comment and i will check back with you

Hi - I've just fixed ny AL1921 which would be similar to yours internally. There are a couple of issues which are common:
Bad soldering around some of the copper coils (insulation may not have been properly stripped and leads to intermittent connection and (much more likely)
Blown electrolytics.
If you have ANY electrolytics on the main board which are swollen at the top or have electrolyte oozing out of them at the top or where they meet the board, then replace them.
My ACER started flickering and switching off randomly (no power light on the front either) and I though the power supply inside was toast. However, I found two electrolytics on the large power board (1000u / 16v) which had a black crust at the top. I replaced these and the monitor sprang back into life. Try to use replacements which have a temperature rating of 105 degrees C. Basically I think these things give out just after the guarantee runs out.
Hope that works for you.

the voltage inverters are the small transformers attached to a small pcb, that is connected to the backlight inverter (cold cathode).
Just in case replacing the capacitors did not work, the second thing to do is to check the backlight inverter. If there is busted light, replace this one too..the last thing to check is the high voltage ballast transformer... if one of these is burnt, it is enough to affect the stability of your supply current. It can also result to a dark portion on your screen or worst , could result to a total black screen..
If you can replace this transformer with the same value, please do so.
If this is a help to you.. please rate this solution...thanks.
Testimonial: "No separate PCB's on power supply, but your advice did make me check out the PCB further, so thank you for your advice. I will be undertaking identification of the inverters. On this model the inverters are built into the PCB, above the power supply input. "
