connector.

3. Short across pins 1 and 4 on connector F2.

4. With the power switch ON, the resistance should be less than 5 ohms.

5. Connect meter between pin 1 (GND) and pin 4 (CONT) on connector H3

(see Figure 8-7).

6. When the contrast control is moved from maximum to minimum, the

resistance range should be at least 8 kilohms.

7. Connect meter between pin 1 (GND) and pin 3 (BRIGHT +) on connector

H3.

8. When the brightness control is moved from maximum to minimum, the

resistance range should be at least 4 kilohms.

9. Replace the pod assembly if any of these checks are not correct.
