According to the phenomenon analysis center adjustment circuit is a problem. p6zservice manual download site
Check center adjustment circuit, measuring field output integration block IC451 5 feet (0.75 V) normal 0.75 V when the measured voltage between 0.1 0.3 slowly rising. Doubt IC451 chip circuit inside the bad, after replacing IC451 fault remains. Doubt whether software data change into maintenance mode change, after the center image up again in a few minutes. Further measurement center adjustment circuit components rancid, when measuring rise, explain D456 voltage value changes, replace D456 CDZJ5.6 (B) after the image back to normal, try to put a few hours later, the phenomenon of image did not move. p6zservice manual download site

This failure occurs when we think happens is a change in the software data, change the data after a few minutes image up again, then measured IC451 voltage found 5 feet when voltage instability, immediately replace IC451 invalid cases, when using a digital multimeter to observe fixed on both ends of the voltage stabilizing circuit D456 voltage will gradually rise, apparently D456 voltage value has changed. Try to replace after everything is ok.p6zservice manual download site
