More. How Transistors Work We begin by discussing the so-called bipolar transistor, such as those shown in Figures 10-42 and 10-43. In normal operation, the transistors emitter-base junction is forward biased, and the base-collector junction is reverse biased, as shown in Figure 10-44a.

  • AC/DC Switch Mode Power Supply Design Guide Fairchild's FPS products are highly integrated off-line power switches with a fully avalanche rated SenseFET and a current mode PWM IC (see Burst Mode Operation figure below). The Green FPS products help reduce the system's stand-by power to below 1Watt with the burst mode operation.

There are many different Viewsonic E70 models, so without the 'VCDTS' model number, one cannot be sure which one is your model. However, the E70-3 version does have its R457 connected to the collector of Q407 via a capacitor (the other end of R457 goes to the base of PNP Q426, in that E70 version), and in that chassis, R457 is 1.5K Ohms, 1/2 Watt.

I can't see any burnt components on the board, but the top of the Motorola IC (LGM871-010/AYJ) appears to have heat damage (it's not a continuous black color on top like most ICs). I have found only one supplier for the IC and it's $49 + shipping to the UK, so I don't want to replace it unless I know it is broken.
