I have a SP72G BenQ Monitor which worked fin for 3 years until one day
when I switched it on and it displayed teh BenQ Logo for a second and
then faded out in a series of colours before switching off.
If I try to switch it back on it does the same but a lot faster. I
guess it maybe a faulty compnent overheating but can not see any
visible signs of burn out etc..

Anyone have any suggestions?

The power supply is starting, but giving up after a few seconds.

Open it up. Inspect the electrolytic cazapitors. If any of them have
bulged, leaked, or volcanically erupted, replace *ALL* the
electrolytic cazapitors.

Make sure your replacements are 105C rated, not 85C. Also, don't try
it while half asleep and install 6 capacitors with reversed polarity,
like I did last month.
