Having problems with your Computer Monitors ?

Image on the screen appears only for 1 second; the green led remains ON. I suspect protection circuit of inverter bd. I can't find the related schematics.


Answers :

I would look inside first for bad caps, then the inverter section, worst case will be bad lamps, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
\015\012The inverter board will go into shut down mode if it detects current overload (bad inverter transformers, or transistors), open lamps circuit (lamp does not stay light up (conduct) after first firing of the lamp), lamps draw too much current.
