| Sony | BE3D | Buzzing only on sound - incorrect sound system selected | audio system can be changed by altering "destination" of set. PAL I can be selected by putting set into service mode as described in the service manual. At "TT" prompt enter "24". After re-tuning set,
sound should return to normal. | plamensl | 14-09-2004 |

| Sony | BE3D | Poor contrast, dim display & dark pic | Check R826, R827, R828 and R829 in ABL cct | plamensl | 14-09-2004 |
| Sony | BE3D | Relay clicks on/off in st/by - ok when on | If 5V supply to micro (IC001) is lost when st/by selected then micro will reset & set will switch on again. Check Q601, D603, Q604, Q603, Q602, & confirm HT is 135v when set on. If HT is too high, replace IC602 & IC601. | plamensl | 14-09-2004 |
| Sony | BE3D | Reverts to st/by at sw on with 2 flashes from LED | Indicates over current or field fault. To eliminate field, dis D505 on main board. If set now sw on check IC500, R510, R509 etc If the problem is not in FOP, check volts on coll Q606. During normal operation this should be 0V. An over-current condition will cause this tr to turn on making its coll high. If so check comps in LOP. If neither of the above conditions is occurring, replace memory chip IC2 on A board. | plamensl | 14-09-2004 |

| Sony | BE3D KV28WS2U | At sw on reverts to st/by with LED flashing twice | Measure volts at collector Q606 (located in the middle of the PCB towards the right edge), if it stays at 0V, then you need to replace or re-set the EEPROM, if it goes high - then overcurrent protection is activated, suspect faulty LOPT. After replacing the LOPT, collector Q606 should stay at 0V and the set should come on, however with some software versions, the error code 2 will remain in the memory and you need to clear
it manually.To clear the error code from the EEPROM you can replace it with a blank one, but it is much easier just to re-set it. While your error code 2 is still flashing, press on the remote control: [5], [-/--], [5], [9], [Standby], [i], [5], [vol+], [TV]. The set will come on in the service mode with TT-- on the screen, press [MENU] and write down all the settings for picture, geometry and sound. Then press [MENU] again to return to TT-- screen. Enter 49 to clear the EEPROM, and switch the mains
off. Now go back to the service mode (TT-- on the screen), enter 24 to set destination "UK", then press [MENU] and enter all the settings what you have written down. The sequence [5], [-/--],[5],[9] sets the TV on program 59; the
sequence [Standby], [i], [5], [vol+], [TV] is used to enter the service mode. In order to execute the command TT49 (re-set EEPROM), the TV must be on program 59. | plamensl | 14-09-2004 |

| Sony | BE3D KV28WS2U | Dead at sw on - will produce a click from relay after a period of time. When G2 advanced, line collapse noticed | Check for dry joints around scan coils plug, check R870M for o/c 1R, 1w | plamensl | 14-09-2004 |
| Sony | BE3D KV28WS2U | EEPROM corruption | Caused by flashover of red gun in crt - crt replaced under warranty (if lucky) | plamensl | 14-09-2004 |
| Sony | BE3D KV28WS2U | LED flashes twice aft LOPTx replacement to cure dead set | Check EEPROM 24C32 in IF sound module by replacement. Enter service mode & at TT promt enter country code 24 (UK system) - prevents need for setting each chan band when tuning | plamensl | 14-09-2004 |
