Re: LCD monitor's Inverter bad ?

Maybe there is a defect in the circuit board, or in some part, that when it
is mounted, something is going opened. Another thing, is that maybe there is
a component that has become temperature sensitive, and it is failing when
there is a little more heat from being mounted.

Try using a heat gun on the inverter to see if it fails. If it stops
working, you can then use some freeze spray on one component at a time until
you find the failed one. Most of the time, the electrolytic capacitors go
bad on these boards.

First, sorry for bringing such an old thread back to life but I wonder
if anyone has any other ideas about this. I have the same problem with
a KDS PixelTouch monitor. I have found an interesting twist to this
problem though. If I leave the inverter plugged in but remove the
screws holding it and position it outside the monitor, it works
perfectly.

Also, if I place the inverter board underneath the LCD and assemble it
while it is working, it will continue to work until power is lost.
Normally I would just replace the inverter but PixelTouch no longer has
any of these. In addition, the original company that made these
monitors (gvision, who sold them to KDS for rebranding) has the
inverters for $25 but will not sell them. They state they are for
internal use only and I'd have to send it in for a $50 repair plus the
$25 part.

I initially thought that it was the positioning of the cables but I've
tried to reposition the connecting cables to no avail. As far as I can
tell, the inverter looks perfect and performs perfect until it is
installed properly.

Any ideas?
