By pressing PLAY the script will proceed to the next test. If the user presses PLAY before OPEN/CLOSE or STOP, the DispLed nucleus will return TRUE (LED test successful). 5.3.3Keyboard Test The keyboard of the DVD player is tested by nucleus DispKeyb. The user is expected to press all keys on the local keyboard once. The code of the key pressed is shown on the local display (1 hexadecimal digit) immediately followed by a (hexadecimal) number indicating how many times that key has been pressed. Example of the local display during this test: Figure 5-7 The key-codes displayed on the local display will scroll from right to left when the display gets full, the text K will remain on display. Figure 5-8 If any keys are detected more than once (due to hardware error), the key-code is displayed twice (or more), with the second digit increased by 1. If the user does not press all keys minimally once (in any order), the DispKeys nucleus will return FALSE and cause an error in the overall result of the player script. The user can leave the keyboard test by pressing the PLAY key on the local display of the DVD player for at least one full second. The result of the keyboard test is shown on local display as follows: Figure 5-9 Or Figure 5-10 Pressing PLAY on the local keyboard again will proceed to the next text. 5.3.4Remote Control Test The remote control of the DVD player is tested by nucleus DispRc. The user must press any key on the remote control just once. The codes of the key pressed will be shown on the local display in hexadecimal format. Example: Figure 5-11 In this example 23 is the hexidecimal code of the pressed RC key. The user can leave the remote-control test by pressing PLAY on the local keyboard of the DVD player. The remote control test is successful if a code was received before the user If OK, press OPEN/CLOSE If OK, press OPEN/CLOSE If OK, press OPEN/CLOSE If NOK, press STOP If NOK, press STOP If NOK, press STOP press PLAY to continue CL 16532162_031.eps 080102 CL 196532162_032.eps 080102 KEY IDKEY 0PLAY 1STOP 2OPEN/CLOSE 3STANDBY 4NEXT 5PREVIOUS 6PAUSE 7AUDIO DIRECT ESOUND MODE FREPEAT CL 26532105_057.eps 300802 CL 16532162_033.eps 080102 CL 16532162_034.eps 080102 CL 16532162_035.eps 140102 RadioFans.CN 收音机爱 好者资料库 Diagnostic Software, Trouble Shooting and Test InstructionsEN 24DVD963SA5. pressed the PLAY key. Pressing the PLAY key, before pressing a key on the remote control, gives an error in the remote control test (note that the remote control test will also fail if a key on the remote control was pressed but no code was received). The remote control test does not check upon the contents of the received code, that is it will not be checked if the received code matches the key pressed. If desired, the user can manually check this code by using a code-table for the remote control key-codes. Figure 5-12 After pressing PLAY, the result of the remote control test is displayed on the local display of the DVD player as follows: Figure 5-13 Or Figure 5-14 Pressing PLAY on the local keyboard again will proceed to the next test. 5.3.5P50 Loop-Back Test For the P50 loop-back test, the user must first press a key to decide if the test is to be performed. The display will show the following message: Figure 5-15 If the user presses STOP, the P50 test will be skipped. If the user presses OPEN/CLOSE, the P50 test is performed and the result is displayed as follows: Test successful: Figure 5-16 Test fails: Figure 5-17 Press the PLAY key to continue to the next text RC Key id Hexadecimal code STANDBY0C 11 22 33 44 55 66 77 88 99 00 RETURN83 DISPLAYEF DISC MENU54 SYSTEM MENU82 CURSOR UP58 CURSOR DOWN59 CURSOR LEFT5A CURSOR RIGHT5B OK5C PREVIOUS21 NEXT20 STOP31 PLAY2C PAUSE30 SUBTITLE4B ANGLE85 ZOOMF7 AUDIO4E REPEAT1D REPEAT A-B3B SHUFFLE1C SCAN2A CL 16532162_037.eps 080102 CL 96532065_013.eps 120799 CL 96532065_014.eps 120799 CL 16532007_004.eps 090102 CL 16532007_005.eps 090102 CL 16532007_006.eps 090102 RadioFans.CN 收音机爱 好者资料库 Diagnostic Software, Trouble Shooting and Test InstructionsEN 25DVD963SA5. 5.4Mono PCB Digital Part 5.4.1Picture Test The picture test is performed by putting a predefined picture (colour bar) on the display (nucleus VideoColDencOn), and asking the user for confirmation. The display will show the following message: Figure 5-18 By pressing OPEN/CLOSE the user confirms the test, pressing STOP will indicate the picture was invisible or incorrect. Pressing PLAY will proceed to the next test. If the user presses PLAY without pressing OPEN/CLOSE or STOP first, the result of this test will be TRUE (picture ok). Note: The colour bar must be simultaneously available on the CVBS, YC, and RGB (or YUV) outputs available. On the SCART only the CVBS and RGB signals will be available. 5.4.2Sound 1 note that this test will not contribute to the test result of the Basic Engine. Pressing PLAY proceeds to the next test, after the disc motor has been shut off with a call to nucleus BeDiscMotorOff. 5.5.8Tray Test As a last action for the Basic Engine tests, the tray test is repeated. The local display will look as follows: Figure 5-29 This test is meant to give the user the opportunity to remove the disc in the tray. The tray position can be toggled using the OPEN/CLOSE key. The tray will be closed (by the software, if it is open) before proceeding to the next test when the user presses the PLAY key. 5.5.9Error Log (See Table on Page 25) Reading the error log and error bits information can be useful to determine any errors that occurred recently during normal operation of the DVD player. Reading the error log is done by nucleus LogReadErr. The display during the errorlog readout looks as follows : Figure 5-30 Note: Previous versions of the diagnostic software showed a 8- digit error code. Due to limitations in the number of digits that can be displayed by some front panel displays, the most significant digits will not be shown. This can be done since all the error codes used by this player has set these 2 digits to “00” By pressing OPEN/CLOSE or STOP the user can move forward or backward (respectively) through the logged error codes. If 0000 is displayed at all positions, the error log is empty. Display of the logged errors is done in a cyclic manner. By pressing PLAY on the local keyboard, the user can proceed to the next test. 5.5.10 Error Bits Reading the error bits is done by nucleus LogReadBits. The display during the errorbits readout looks as follows: Figure 5-31 Only the identification number (decimal) representing set errorbits will be shown. By pressing OPEN/CLOSE or STOP, the user can move forward or backward (respectively) through the logged errorcodes. If the display only shows EB-0, no error bits were set. By pressing PLAY the user can continue to the next test. 5.6Loop Test (See Table Below) At the start of the loop test, the local display of the DVD player will show the interactive player test result readout in the following display: Figure 5-32 The left side of the display contains a 3-digit code, which can have a value between 000 and 111. These values indicate the faulty modules and are to be interpreted as follows: Figure 5-33 The loop test will perform the same nuclei as the dealer test, but it will loop through the list of nuclei indefinitely. The display of the DVD player will display not only the three digits indicating correct/faulty modules and the last found error code (as mentioned, faults are detected as far as they can be within the scope of the diagnostic software), but also a loop counter indicating how many times the loop has been gone through. If an error was detected, the display will remain as in figure 5-34 until the user presses the PLAY key and then it will continue to the next loop. Example: Figure 5-34 The 2-digit number (23) on the right of figure 5-32 indicates the number of times the loop test has been performed.

After one loop cycle: Display the 3-digit module bits together with the last error code which occured in the loop test. The 4 digits at the right side of the display (fig. 5-34) show the last error that was found during the loop test. The leftmost two digits (54) of this code indicates which nucleus resulted in a fault. The rightmost two digits (03) refer to the faultcode within that nucleus. For further explanation of this error code, refer to chapter 5.8 (Nuclei Error Codes). 5.6.1Errorlog Explanation: The application errors will be logged in the NVRAM. The maximum number of error bytes that will be visible is 16. The first word (4 digits) of the byte is the component identification, the last word is the error code. The diagnostics software will present a combination of this component identification plus an error code on the local display (and on the attached terminal). The last reported error is shown as and the errors in between as . The devices that may report errors are the serial controller (UART), the basic engine (BE), the slave processor (SLPH), the SACD Stream Manager (SSM) and the SACD Media Access (SMA). The identification of these components is as follows: The tables in the next chapters list the error code and corresponding problem. The column Explanation holds a more elaborate description and the most likely reason for the error. Some Examples: 002E0000 (SMA reported a timeout error) 0016010A (Engine could not fully close or open the tray) D0010001 (Flash checksum failed).
