Question about BenQ FP71G 17" LCD Monitor
This may sound like a silly question, but how do you tell which electronic components may be faulty? Also, how do you tell which components are which?
Would an assumption that every component that leaked out white "goo" should be replaced first? There are three components on a circuit board that appear to have leaked something out. One is black, cylidrical, and about 4cm long. Side reads PW(M)105C (C)0516. The others are blue, about the size of an aspirin tablet, and read SEC 222M SE 220V~X1 Y1 400V~C.
If there is another thread that I should refer to for help that would be appreciated as well.
I checked all what is explained here but, first, all the components are ok, then my problem is a little bit different from this.
My monitor (Benq FP71G+) turns on perfectly but after about 1 hour or less the LCD panel turns off (so backlight and signal, if I check with a light spotted on to the LCD panel I don't see anything) but power LED is green.
If I turn off and then on it turns on again but the brightness start to dim and then the screen go off.
If leave it off for about two minutes (but sometimes for a couple of seconds!!) then it works again for another hour (or less...).
I thinked to change capacitors (not SMD).
What do You think?

The white goo you refer too is actually glue =)
If you could let me know a little more about what your screen is/is not doing then I can help further.
I will assume you have a power light on the front, but no picture.
If so, then you have a failed inverter circuit. This will require someone with a mild technical knowledge to diagnose and repair.
Hope that helps =)
