Here’s the skinny on replacing a power supply on an LCD flat-panel monitor. It’s not pretty, or flat, but it works. I had this exact problem with a flat panel a few years back (shutting off after a few minutes of use) and had no idea it was this easily (relatively) fixable.

    This could have been executed more eloquently. Most monitors draw under 4 amps. If you were to buy an external switching power supply good for 12 volts (or more) and then used 78xx or similar ICs the giant brick at the back of this monitor would be no more. Keep in mind that the 78xx create a ton of heat when operating at full capacity and it is required to put them on a heat sink. (Monitor chassis)
