What symptoms are likely the result of a low voltage power supply problem?
There are an almost unlimited number of possibilities but the following probably covers the most likely: • Monitor is as dead as a concrete block – no picture or raster, no LEDs lit, no sounds of life (like degauss) of any kind. Most likely causes: No power at AC outlet or outlet strip, bad or loose line cord, bad power switch, blown fuse due to internal short or overload. • No picture but unusual sounds like a whine, periodic clicks, tweets, or flubs, and/or possibly flickering or flashing front panel LEDs. Most likely causes: Excessive load or short on output of power supply (shutdown or cycling due to overcurrent) or loss of horizontal drive (cycling from overvoltage due to lack of load). • Unusual aromas, smoke, or six foot flames coming from inside the case. Most likely causes: Failed parts in low voltage power supply, deflection, or high voltage sections. Actually, while burning smells and even smoke aren’t that unusual when parts overheat as a result of a short circuit, actual f
