4.After the brief communications above, the servo IC701 must initialize the mechanism by closing the tray and moving the sled to home posi- tion. When completed, IC701 replies to Syscon IC202. If no reply is received within approximately 2 seconds of powering ON, IC202 in- structs Interface IC201 to power down (set OFF). For details, see the Mechanism section, Tray Motor Drive section and the Initial Sled Drive section of this training book.

No DVD OSD logo

The DVD initial OSD power ON logo is stored in Flash ROM IC205. This information takes the following path to become video that outputs the AU212 board:

1.Flash ROM IC205 (storage)

2.Syscon IC202 (extraction and processing)

3.ARP2 IC303 (pass through)

4.A/V Decoder IC401 (sub-picture generation)

5.Video Buffers on the AU212 board

In the test mode (Syscon Diagnosis/A/V Decoder test), the A/V Decoder can generate a main picture (color bar) or a sub picture (“CHG_COLCON”) from the flash ROM data. Unfortunately they take the same path as the logo, finally separating inside the A/V decoder IC401. Therefore if the logo, test bars or test sub picture does not appear, the problem may be the storage area in Flash ROM IC205. If none appear, the path from Flash ROM to A/V Decoder IC401 is broken.

1.Use the test mode to perform the DVD auto adjustments using the DVD test disc.

2.Use the test mode to examine the OSD emergency code entries for failures. The emergency code list description is in the DVP-S330/ S530/S550/S705 service manual on page 6-10E. The front panel customer code errors are preceded by a C and listed on page 6-4 of the manual.

3.Use the test mode to manually play the DVD disc by activating servos 1-6 individually.

4.The minimum (marginal) eye pattern amplitude is 0.8Vp-p @ CN012/ pin 1. Clean lens or replace laser. Follow eye pattern into ARP2
