| Akura | Baby 10 | Brightness - no control | D409 o/c | 14-09-04 |
| Akura | Baby 10 | Dead - list of psu 2 faults | Fault 1: Dry joints on IC402, also check 12V socket.
Fault 2: Line output transistor is dry jointed (emitter).
Fault 3: Check if fuse holder 5AT is loose.
Fault 4: Replace D410 in line stage with two RGP30 in parallel.
Fault 5: Check regulator block for dry joints.
Fault 6: Check D410 (FR604) in the line output stage. | 14-09-04 |
| Akura | Baby 10 | Dead - list of psu faults | Fault 1: Check output of regulator IC402. S/C in DC jack may blow the 5A/T fuse. Note: IC402 can cause other faults, such as oversized picture with bent verticals.
Fault 2: Check L110 for dry joint.
Fault 3: [No 12V at regulator]. Check R402 (1R/0.5W) for O/C.
Fault 4: Check line drive transformer (TX EM103) for dry joints.
Fault 5: Check print between output and destination of (potted) regulator for O/C.
Fault 6: Check line output transistor for broken print.
Fault 7: Check fuse F402 and diode D402, damage due to incorrect connection of battery.
Fault 8: Replace IC402. Check EEprom chip IC601 (MN1220).
Fault 9: Check regulator IC401 (L7812).
Fault 10: Check the DC input sockets for high resistance.
Fault 11: [5A fuse blown]. Check D412 FR155 diode for S/C a BY299 will do.
Fault 12: [Regulator OK]. Check line drive transformer for dry joints.
Fault 13: Check mains transformer for O/C.
Fault 14: [630mA fuse by switch O/C]. Check bridge rectifier for S/C. Use 1N5401 as replacement.
Fault 15: Check IC402, F401 (630mA) fuse and D403, D405 in the bridge rectifier circuit.
Fault 16: [F401 blown]. Check D404.
Fault 17: [No PSU start up]. Check resistors R301 (330K) and R302 (330K).
Fault 18: Check 12V DC-IN socket. | 14-09-04 |
