Question

Hello, I have a Acer 19 inch LCD monitor that was working fine and then I noticed that after I turned it on , it would go blank after about 30 seconds. Then it progressivly got worse: blank after about 20 sec. 10 sec ,5 sec and now it goes blank almost instantly. I read on line that it is probably a capacitor so I took it apart and visually checked ALL the caps for any leakage , swelling  or buldging . They all look like brand new.! This has really got me stumped.I ruled out capacitors so it might be one of those little resistors. I am now back to using my old but reliable 15 inch Dell CRT monitor and it works perfectly. At least I know that I dont have a computer or Vga cord problem ! Any help would be appreciated because I really dont have the money to buy a new monitor !

Thanks

It sounds as though the invertor is bad, it powers the LCD to make them visible.  Half split the output of the inverter.  I do not have acess to schematics and test points to further aid in componant troubleshooting.  There are others that may be able to tell you what a standard voltage output should be.

Thanks for trying to help. Do you have any means to send me a picture of the inverter so I can possibly check it out ?
This just may be the cause !
Thanks again.
