I have an HP Pavilion f1903 19" LCD monitor that has gone bad. The symptoms are a blank screen and a flashing power light. Google finds are pretty consistent that the problem is with the inverter board supplying the back lights. My DMM shows a few volts on the 4 outputs - not the "high" voltage warned of.
Google found this page that describes the fix(es):or
It says first look for cold solder joints. I couldn't find any, but my eyes aren't what they used to be, even with a magnifier 8-(. Then, bulging caps (none of those), replace them anyhow. And, "might as well replace the power transistors while you're at it".
If that's what it takes, it's not so bad (4 caps, 4 transistors, on a single-sided board). But I'd rather a more methodical approach that would actually identify the bad part(s), since I don't have the replacement caps & transistors.
Your advice would be appreciated, Bob
