I would start looking at the power supply, it's usually a separate board where the a/c line plugs into. In many cases i have seen that the problem you described is from a damaged power supply, sounds like something is shorting causing the power supply to continuously come on and off. I would first check the capictors to see if any of them have blown, usually cylinder looking and sometimes you'll see an X or a K at the top of the cylinder, if it's blown then the top will be bulging out instead of being flat. If all those look good then there is probably a short somewhere else like in one of the transistors, if so you'd be best to just find another power supply board to replace.

it would be easier to find it stripped from a damaged set on ebay.
I see several there but need the part number to search
of course you may purchase that and find it to be the lcd driver.hopefully not.

You probably have a sacrificial diode that blew out to save the rest of the monitor from further damage. The manufacturer should replace it with a refurbished one at little and sometimes no charge (comparatively speaking).
