COLOR PROBLEMS

A helpful hint when working with color problems is to first identify the color of the three grid lines at the top of the screen.

When there is a missing color and the lines are white, the problem lies in the video interface section. This means it can be found in between the video source and pin #8 of the Video Amplifiers (K-PRA). If the lines were not white it would be an output problem, which is anything after pin 8 to the picture tube.

Use the following steps when troubleshooting a missing color.

1. First determine if it is an input or output problem.2. If it is an input problem check pins 16, 13, and 9 on IC 241(Video Interface IC). If the

color you are missing has a DC voltage higher or lower than the other two colors by .3V replace IC 241.

3. If the voltages are all the same check for an open between the output pins of IC 241 and pin 8 of Video Amplifiers (K-PRA).

4. If you determine it to be an output problem check pin 20 of the Video Amplifiers (K-PRA). If the voltage at pin 20 for the color that is missing is a minimum of 20 volts higher than the other two colors. Replace the Video Amplifier (K-PRA) and Transistors at 945, 812 or 822, depending on which Video amplifier is being changed.

NOTE: All voltage measurements are DC with –lead to GND unless otherwise noted.

Monitors with zero voltage at V+•Ohm out the zener diode at location 181.•Replace the zener if it is shorted, check the FET to make sure it is not shorted.•Replace the FET if it is shorted.•Apply power to the monitor.•Note: Insure board is completely discharged. Caps loc. 144, 163, and 175. •If you still have no V+ voltage replace IC 115 and Transistor (MPSA64) 127. •A quick ohm check for IC 115 is, V- (J-PRA side of loc. 137) to pin 1 of IC 115 should read between 10.5K ohm and 11.5K ohm.•Also check V- (J-PRA side of loc. 137) to pin 16 of IC 115, should read between 27K ohm and 28K ohm.

Monitors with 10–35 volts at V+•If the V+ reads between 10-35V DC replace IC 115 and Transistor (MPSA64) 127.

Monitors with a fluctuating V+•Check the 16V line at diode 170(See illustration 102).•Measure the 12V-regulator input and output for shorts (output .•Measure pins 8,11 and 12 on IC (LA7851) at location 415.

Monitors with a fluctuating V+•Check the 24V line at diode 168. (See illustration 103)•Check the vertical IC (LA7838) and relay (location 468) for degaussing circuit that requires 24V.• A quick ohm check with out the need for external power would be GND to pin 12 of vert. IC (location 377). Replace if shorted.
