Troubleshooting Static Sensitive Devices

Certain precautions must be taken when working with static-sensitive devices, e.g., microprocessors, field-effect transistors (FET), complementary metal-oxide semiconductors (CMOS), and other large-scale integration (LSI) devices that use metal-oxide semiconductor (MOS) technology. Static charge buildup in a person's body or leakage from an improperly grounded soldering iron can cause static-sensitive device failure. Before handling a static-sensitive device or a PCB with such devices attached...

The Motion Object Test appears is shown in Figure 2-9. The Motion Object Test indicates the condition of the motion-object buffer circuit. There are fifty-six objects, eight pixels wide, placed in two rows in the center of the screen. The following information is provided at the bottom of the screen OBJECT indicates the number of the motion object selected. PICTURE indicates the stamp number in ROM. HORIZONTAL indicates the horizontal position of the object. VERTICAL indicates the vertical...

Removing Integrated Circuits

The easiest and safest method for removing soldered-in integrated circuits (IC) from a PCB is to cut off each pin as close to the IC case as possible with a tip dyke (diagonal cutter) as shown in Figure 4-1. Use the proper soldering iron as previously described under Soldering Techniques. Then, to avoid excessive heat buildup in one area of the PCB, apply heat directly to each pin in a random order. Remove the loosened pin with the tip of the soldering iron or a needle-nose pliers as shown in...

Convergence Test

The Convergence Test is shown in Figure 2-13- This test indicates the condition of the display size, centering, linearity, and convergence. The grid pattern should be white. Press the left Start button and the grid pattern should turn violet. Pressing the left Start button again should cause the grid pattern to turn green. Check the grid pattern for good, the word GOOD should appear. If the sound microprocessor or associated circuitry is faulty, a number will appear (to indicate sound status)...

Self Test

The Xybots game tests itself and provides visual and audible indications of the condition of the game circuitry and controls. Self-test information is displayed on the screen and through the sound system. No additional equipment is required. We suggest that you perform a self-test when you first set up the game, each time you collect the money, or when you suspect game failure. Thirteen self-test screens provide information pertaining to the game circuits and controls. The game enters the...

Play Mode
