XP-30 Mar. 19993 : Advancing to the next testWhen a test ends normally, you will automatically advanceto the next test item. Details of the test items0 : Test mode top pageAfter setting the rear panel select switch to the "Mac" Even if a test has not ended, you can press the cursor [↓]button to move to the next test item.position, turn on the power while holding down the threebuttons [CONTROLLER], [-OCT] and [EXP A].However in the Switch & LED test, you must press the twobuttons [SHIFT] and cursor [↓].4 : Returning to the preceding testPress the cursor [↑] button.However in the Switch & LED test, you must press the twobuttons [SHIFT] and cursor [↑]. Confirm the software version number.If the version number is inappropriate, update the software asrequired. For the update procedure, refer to "Updating thesoftware."5 : Jumping to a specific testIn the top page of test mode, you can press [SHIFT] + [***]to jump directly to a specific test. If the "Battery" item does not produce the "OK" displayCheck the BH-1, Battery, and IC12 on the main board.1 : Memory test [SHIFT]+[1]2 : Expansion board test [SHIFT]+[2] * If the battery voltage V(batt) is 2.5 < V (batt) < 4.0, thedisplay will indicate "OK."3 : MIDI test [SHIFT]+[3]4 : A/D test [SHIFT]+[4]5 : Aftertouch test [SHIFT]+[5]6 : Switch & LED test [SHIFT]+[6]7 : LCD & Encoder test [SHIFT]+[7] Check the "Memory Card" display.NONE : no card is insertedPROTECTED : the card is protectedNON-PROTECTED : the card is not protected8 : Card test [SHIFT]+[8]9 : Computer I/F test [SHIFT]+[9]10 : Sound test [SHIFT]+[0] If the display is wrong,Check CN5 and IC15 on the main board.11 : Factory reset [SHIFT]+[CATEGORY] Turn off the power, change the status of the card slot, and12 : Version check [SHIFT]+[UNDO] verify the altered status.13 : Checksum check [SHIFT]+[PALETTE] After verifying the three different states (NONE,14 : Test check [SHIFT]+[ENTER]PROTECTED, NON-PROTECTED), press the cursor [↓]button to proceed to the next test.12
XP-30 Mar. 19991 : Memory test 3 : MIDI testUse a MIDI cable to connect MIDI IN and MIDI OUT.If the "NG" display appears, verify the item which is "NG,"and check the following components on the main board.Use a MIDI cable to connect MIDI IN and MIDI OUT.Verify that the display indicates "Connect."CPU NG → IC5 → If this is not displayed, check IC4, IC8, and JK1 on the mainROM NG → IC1(Mask ROM), IC7(Flash ROM) → board.DRAM NG → IC9SRAM NG → IC14DSP DspNG → IC24DSPRAMNG→ IC35Wave NG → IC22 → → → → → Disconnect the MIDI cable from MIDI IN and MIDI OUT.Verify that the display indicates "OK."When all items are displayed as "OK," you will automaticallyproceed to the next test.If the "OK" display does not appear,check IC4, IC8, and JK1on the main board.2 : Expansion board test When the "OK" display appears, you will automaticallyproceed to the next test.4 : A/D test If the "NG" display appears, verify that the two expansionboards are inserted correctly.If they are inserted correctly, verify the item for which "NG"was displayed, and check the following components on themain board.Move the bender all the way to the left and right.EXP-A NG → IC23, RA38, RA39, RA46EXP-B NG → IC27, RA38, RA39, RA46EXP-C NG → IC28, RA38, RA39, RA46EXP-D NG → CN6, IC20, IC25, IC26, IC30, IC31, RA45EXP-E NG → CN7, IC20, IC25, IC26, IC30, IC31, RA45 → → → → → Verify that "Bend" indicates "OK."If "OK" does not appear for "Bend,"check IC45 on the mainboard, or the bender unit.Move the bender lever in the modulation direction.When all items are displayed as "OK," you will automaticallyVerify that "Mod" indicates "OK."proceed to the next test.If the "OK" display does not appear for "Mod,"check IC45 onthe main board, or the bender unit.Move C1, C2, C3, and C4 sliders all the way upward anddownward.Verify that "OK" is displayed for "C1", "C2", "C3", and"C4."If the "OK" display does not appear,check CN10 and IC46 onthe main board,and CN1, IC1, VR1, VR2, VR3, and VR4 onpanel board A.Connect an expression pedal to the control jack, and a footpedal to the hold jack.Advance and then return the expression pedal.Verify that "OK" is displayed for "Pdl."If "OK" is not displayed for "Pdl,"check IC10 and JK2 on themain board.13
