| '''Description:''' This common problem is not mentioned on the RMS webpage. It's usually caused by problems in the 4 pin connector (marked "P5" on the analog card) interface between the analog card and the CRT yoke. One or more pins in the analog card connector develop bad solder joints. A bad solder joint can cause excessive heating which causes heat corrosion in the associated pins within the 2 connectors. The heat corrosion will cause discoloration of the white connector shells. | | '''Description:''' This common problem is not mentioned on the RMS webpage.

| + | ===Checker Flag Pattern=== |
| + | ====Symptoms==== |
| + | When turning on the power, you don't hear startup bong. The monitor displays the checker flag pattern. |
| + | |
| + | ====Diagnosis==== |
| + | # The most probable cause is connection troubles between the ROM-SIMM and the ROM-SIMM slot. |
| + | # Another cause is inappropriate installation of RAM-SIMMs. The memory size of RAM-SIMMs in Bank A is smaller than that in Bank B. You recently upgraded the memory but the configuration was wrong. |
| + | |
| + | ====Solutions==== |
| + | # Pull out the ROM-SIMM from the ROM-SIMM slot. Clean the ROM-SIMM and the ROM-SIMM slot with volatile cleaner or ethanol. Then connect the ROM-SIMM to the ROM-SIMM slot correctly and tightly. |
| + | # See "Principles of memory upgrade for the SE/30" in the next section, 8. Jail Bar Pattern or Smile Mac in Jail. |
| + | When you install SIMMs of different memory size, install the larger ones to Bank A and the smaller ones to Bank B. Each Bank requires a set of four SIMMs of the same memory amount. |
| + | |
| + | ===Jail Bar Pattern or Smile Mac in Jail=== |
| + | ====Symptoms==== |
| + | When you turn on the SE/30, the monitor displays vertical stripes (jail bar pattern) with/without a smile Mac. The memory was upgraded recently. The SE/30 was completely nomal before memory upgrade. |
| + | |
| + | ====Diagnosis==== |
| + | SIMMs were inserted to the wrong SIMM slots/banks. |
| + | |
| + | ====Solutions==== |
| + | * The working memory configurations for the SE/30 are shown in the table below. |
| + | * Check and re-insert the SIMMs. |
| + | |
| + | ====Note 1==== |
| + | The SE/30 has eight RAM-SIMM slots on the logic board: Four slots at Bank A and four slots at Bank B. |
| + | Principles of memory upgrade for the SE/30: |
| + | # Use 30-pin SIMMs. |
| + | # You need to install a set of four SIMMs of the same memory size to each bank. |
| + | # When you use only a single bank, use Bank A. |
| + | # When you install SIMMs of different memory size, install the larger ones to Bank A and the smaller ones to Bank B. You also have to remember that each Bank requires a set of four SIMMs of the same memory amount. |
| + | # It has been reported that some 2MB SIMMs and some 16MB SIMMs don't work for the SE/30. |
| + | |
| + | ====Note 2==== |
| + | The SE/30 has a "dirty ROM" that can recognize only 8MB RAM, and the maximum RAM for the SE/30 is 8MB under the normal condition. |
| + | But if you install the MODE32 extension file, the SE/30 can recognize up to 128MB RAM. |
| + | |
| + | ===Bright Monitor with neither Arrow Pointer nor Startup=== |
| + | [[File:Network filter.gif|left]] |
| + | ====Symptoms==== |
| + | When turning on the power, you can see bright rasters on the monitor, but neither startup bongs nor arrow pointer comes up. |
| + | |
| + | ====Diagnosis==== |
| + | * The culprit is the network filter located on the logic board at reference RP2. |
| + | * The model of the chip is Bourns 4120R-601-250/201, M/C 8908L 115-0002 or P9120M115-0006, depending on the lot, year and/or country where the logic board was made. |
| + | |
| + | ====Solutions==== |
| + | # Replace the network filter. |
| + | # This network filter chip, however, is hard to find/obtain at resale parts shops. If you have a skill to make it yourself, refer the circuit schematic of the filter as shown in the left figure. It is made of sixteen 25 ohm resistors and eight 200pF capacitors. Assemble and solder them on a small IC socket, and then solder this socket on the logic board at reference RP2. |
| + | |
| + | ===An Arrow Pointer on the Left Upper Corner but No Smile Mac and No Startup=== |
| + | ====Symptoms==== |
| + | When turning on the power of the SE/30, the monitor shows the bright rasters and an arrow pointer appears on the left upper corner. But the monitor doesn't show a smile Mac, and the SE/30 doesn't start up. |
| + | |
| + | ====Diagnosis==== |
| + | The most probable cause is a trouble of the SCSI chip on the logic board at reference UI12. |
| + | This chip is labeled "NCR 53C80 CP02346 609-3400257 8907N" on the top. |
| + | |
| + | ====Solutions==== |
| + | Replace the UI12 SCSI chip with new one (44-pin PLCC, 53C80-P44). |
| + | |
| + | ===Monitor Out of Focus=== |
| + | ====Symptoms==== |
| + | The monitor of the SE/30 is out of focus. Except that, everything is OK. |
| + | |
| + | ====Diagnosis==== |
| + | The variable resistor at reference R27 on the analog board is not adjusted correctly. |
| + | |
| + | ====Solutions==== |
| + | Open the SE/30 and look at the vinyl jacket of the analog board. You can see a hole labeled Focus Control. |
| + | Adjust the focus using a hex tool (or screw driver) put into the hole. |
| + | If you cannot get the best focus only with re-adjustment of R27, replace the R26 (not R27) resistor with new one (1 Mohm, 1/2 W, 5%). |
| + | |
| + | ===Too Bright Monitor with Horizontal Sweep Lines=== |
| + | ====Symptoms==== |
| + | The SE/30 monitor is too bright, and you can see many horizontal sweep lines. |
| + | Even if you adjust the brightness control under the front bezel, the symptom is not improved. |
| + | |
| + | ====Diagnosis==== |
| + | There are five known causes for this symptom. |
| + | # The R24 variable resistor on the analog board is not adjusted correctly. This resistor controls the cut-off voltage. |
| + | # Troubles of the resistors R20 and/or R21 on the analog board. |
| + | # Troubles of the resistor R25 on the analog board. |
| + | # Troubles of the IC chip U1 on the analog board. |
| + | # Troubles of the transistor Q1 on the video board. The video board is a small board where the CRT socket is soldered. |
| + | |
| + | ====Solutions==== |
| + | # On the vinyl jacket of the analog board, you can see Focus Control, Brightness Control, Width Control and Height Control for video adjustments. Using the plastic hex alignment tool (screwdriver may be OK, if you don't have the hex tool) put into the Brightness Control hole, adjust the brightness so that the sweep lines disappear and the monitor shows the best images. |
| + | # If the above solution doesn't work, replace either or both of the resistors R20 (100 Kohm, 1/2 W) and R21 (1 Mohm, 1/2 W). |
| + | # If solutions (1) and (2) don't work, replace the resistor R25 (470 Kohm, 1/4 W). |
| + | # If solutions (1), (2) and (3) don't work, replace the U1 IC chip (74LS38). |
| + | # If none of the above doesnt't work, replace the transistor Q1 (2N3904, NPN transistor) on the video board. |
| + | |
| + | ===A Bright Pixel at the Center of the Black Monitor=== |
| + | ====Symptoms==== |
| + | When you turn on the The SE/30, you can see only a bright pixel at the center of the black monitor. |
| + | This phenomenon appeared after disassembling and reassembling the SE/30. |
| + | |
| + | ====Diagnosis==== |
| + | Both horizontal and vertical sweep circuits on the analog board don't work. |
| + | Although both circuits may be broken simultaneously, this possibility is very small. |
| + | This occurs most frequently when you disassemble and reassemble the SE/30. The most probable cause is that the yoke cable does not connect tightly to the P1 connector on the analog board. |
| + | |
| + | ====Solutions==== |
| + | Disassemble the SE/30 again, and check the connection between the yoke cable/connector and the P1 connector. |
| + | |
| + | ===Wavy Display, Swaying Back and Forth of the Image=== |
| + | ====Symptoms==== |
| + | Normal startup and normal display. But for a short period, the display is sometimes wavy, and the image is swaying back and forth (or small and large) on the display. Then, the display becomes normal. |
| + | |
| + | ====Diagnosis==== |
| + | The power supply is getting degraded and unstable with ageing. All components of the SE/30 can be affected by instability of the power supply. The monitor is most vulnerable, because it requires very high voltage. This symptom, in general, indicates fluctuation of voltage for the monitor. |
| + | |
| + | ====Solutions==== |
| + | Replace the power supply. |
| + | The power supply of the SE/30 (and SE) was made by SONY and ASTEC. The SONY power supply has less trouble than the ASTEC. |
