Here is what to test for
| LOCATION | READING | TYPE OF TEST | HOW |
| Video Input Socket | Continuity | Continuity | Test each pin to make sure there is a good connection to the locations down circuit. My meter beeps when there is continuity. |
| Q1 | around .6 or .7 volts | Diode | Flat part facing you, red lead goes to center pin. Black lead goes to left or right pin for readings. |
| Q2 | around .6 or .7 volts | Diode | Flat part facing you, red lead goes to center pin. Black lead goes to left or right pin for readings. |
| Q3 | around .6 or .7 volts | Diode | Flat part facing you, red lead goes to center pin. Black lead goes to left or right pin for readings. |
| Q201 (On neck board) | around .6 or .7 volts | Diode | From the back of the board the upper right pin will be the bridge, put the red lead there. Black lead to other pins for readings. |
| Q202 (On neck board) | around .6 or .7 volts | Diode | From the back of the board the upper right pin will be the bridge, put the red lead there. Black lead to other pins for readings. |
| Q203 (On neck board) | around .6 or .7 volts | Diode | From the back of the board the upper right pin will be the bridge, put the red lead there. Black lead to other pins for readings. |
| Red-Cut Off (VR201) | around 2k ohms | Continuity | Turn the POT dial all the way left or right and test each way. One lead on middle pin and the other lead to left or right to get readings |
| Red-Drive (VR202) | around 200 ohms | Continuity | Turn the POT dial all the way left or right and test each way. One lead on middle pin and the other lead to left or right to get readings |
| Green-Cut Off (VR203) | around 2k ohms | Continuity | Turn the POT dial all the way left or right and test each way. One lead on middle pin and the other lead to left or right to get readings |
| Green-Drive (VR204) | around 200 ohms | Continuity | Turn the POT dial all the way left or right and test each way. One lead on middle pin and the other lead to left or right to get readings |
| Blue-Cut Off (VR205) | around 2k ohms | Continuity | Turn the POT dial all the way left or right and test each way. One lead on middle pin and the other lead to left or right to get readings |
| Blue-Drive (VR206) | around 200 ohms | Continuity | Turn the POT dial all the way left or right and test each way. One lead on middle pin and the other lead to left or right to get readings |
| IC 1 | I don’t know | N/A | Not sure how to test this but I replace it of all the other stuff is good. On pins 1 and 22 there needs to be a 223k capacitor. Should already be there. |
Pictures of the neck board pots:
Here is what a lifted pad looks like on pin 1 of the video port. This is why red was not working.
More to come on this but this is all I have so far.
