| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | BE3D KV28WS2U | St/by only LED flashes error code 2 | Instead of replacing the EEPROM try the following - Whilst LED is flashing enter serv mode (St/by, I, 5, vol+ & TV). This disables prot & set comes on with "TT--" . Press "0, 8" on R/C which will clear error buffer. | ||
| Sony | BE3D KV28WS2U | LED successively flashes twice | M24C32-MW6T EPROM IC2 - 8 leg sm device pt no 875952494 | ||
| 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 | ||
| Sony | BE3D KV28WS2U | EEPROM corruption | Caused by flashover of red gun in crt - crt replaced under warranty (if lucky) | ||
| 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 | ||
| Sony | BE3D KV28WS2U | BUZZING NOISE THROUGH SPEAKERS | CHECK EARTH CONNECTION ON CN303 PLUG FOR O/C OR DRY JOINT | ||
| 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. | ||
| Sony | BE3D KV28WS2 | VOLUME VARIES, CHANNELS WIPE FROM MEMORY, UNUSUAL CHARACTERS DOWN SIDE OF SCREEN | REPLACE IC3 WITH PREPROGRAMMED NEW TYPE | ||
| Sony | BE-3D KV28WF1U | pic does not zoom forward or back in widesreen zoom mode | this is correct for TV, once in zoom mode the remote would only move pic up or down (for subtitles etc) | ||
| Sony | BE-3D KV28WF1U | no pic (unless contrast and brightness are fully up) | R828 22k on LOPTx pin 7 gone high | ||
| Sony | BE-3D KV25X1U | dead, no LED | IC600 STRS6707, R605 0.27R o/c | ||
| Sony | BE-3D KV25X1U | dead, HT down to 24V | no 5V supply, replace IC604 (875936613) | ||
| Sony | BE-3D KV25X1U | burst of EHT for 5 sec, then dead | LOPTx (145316912) | ||
| Sony | BE3D KV25X1U | LED flahes 19 times at sw on | Multiple devices not acknowledging - Fuse PS603 o/c | ||
| Sony | BE3D KV25X1U | E/W faulty | Q800 in pin cush out cct leaky |
