7、Check noise with small speaker and RCA shorted plug18-Put in burning benchCD/DVD-1CD/DVD-1FINAL TESTClass - 151. Before final test unit was 4 days on burn-in-bench with music.2. Take the unit from burn-in-bench to Q.C and play it immediately. Keep the line 120V A.C.3. Check physically and check the
8、components.-check all capacitor and devices direction. Capacitor stand up right way i.e. check co-solder.-check any missing parts.-check all fuse sockets.-check main board tight up with screw and washer.-check any screw missing.-check balance lock working smoothly.-check all output transistors posit
9、ion with pad.-check main transistors position with pad.-check main transformer tight very well.4. Adjust bias 26mV for every output devices for both channels. Wait 7 to 8 minutes after each adjustment. Also adjust offset to 0mV.5. Measure rail and pre-driver voltage.6. Measure A.C voltage for bridge
10、.7. Measure supply voltage for relays. +15V and 15V for both channels. +12V and 12V.8. Measure reference voltage 8.1V on both channels.9. Measure reference voltage for protection 78V.10. After setting the bias, connect load and input signal. Check output signal. Check phase with input signal.11. Mea
11、sure frequency response, slew rate, gain, signal to noise ratio.12. Check the output signal from 20Hz to 20KH with load in following combination. Also measure the output power.Regegur-stereoBalance-stereoRegegur-monoBalance-mono13. Check phone-jack.14. Check protection on both channels.15. Check noi
12、se with speaker.16. Put the jumpers and varistor for required A.C voltage.17. Plug unit again and check rail and pre-driver voltage.DIAGRAMSCD/DVD-1POWER SUPPLY - B2A1XR03 (1)Class - 16CD/DVD-1Class - 17POWER SUPPLY - B2A1XR03 (2)CD/DVD-1RIGHT OUTPUT - B2A2XR02 (2)Class - 18CD/DVD-1VIDEO OUTPUT - B2
