| Sony | BE3D KV28WS2U | LED successively flashes twice | M24C32-MW6T EPROM IC2 - 8 leg sm device pt no 875952494 | plamensl | 14-09-2004 |
| 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. | plamensl | 14-09-2004 |
| Sony | BE3D KV28WS2U | St/by only LED flashes error code 2 | LOPTx can be cause, confirmed by measuring volts coll Q606 in prot cct. If it rises to 11v LOPTx faulty (should be 0v) - then enter serv mode & disable prot (see other entry). | plamensl | 14-09-2004 |
| Sony | BE3D KV29F2U | Height excessive varies with pic content then collapses aft 3 mins shuts down with LED flashing error 2 | IC606 LM2940CT 9V regulator s/c from input to output in PSU secondary,
thus the +9V line was high and varied with picture content. | plamensl | 14-09-2004 |
| Sony | BE3D KV32WF1 | NO SOUND | REPLACE IC1200, PS602, Q1200 AND Q1201 | plamensl | 14-09-2004 |
| Sony | BE3D KV32WF1U | DEAD WITH POWER SUPPLY SCREAMING | REPLACE LINE O/P TRANSISTOR Q802 | plamensl | 14-09-2004 |
| Sony | BE3D KV32WF1U | Serrated line at top & bottom of screen | Fit improved line driver trfmr pt no 1-437-090-31 | plamensl | 14-09-2004 |
| Sony | BE3E KV28FX20 | No chan change unless menu pressed first | EPROM chip corrupted - ok once set was autotuned again | plamensl | 14-09-2004 |
| Sony | BE4 | Dark pic | C823 0µ022 250v leaky in beam lim cct | plamensl | 14-09-2004 |
| Sony | BE4 | Dead - LED blinks 6 times (Field fault) | TDA9302H FOP chip dry jointed and u/s | plamensl | 14-09-2004 |
| Sony | BE4 | Dead - LED flashes 6 times then repeats | Over current problem - Loptx u/s | plamensl | 14-09-2004 |
| Sony | BE4 | Field collapse | No 24v supply to IC501 - R814 0R47 ?w fusible o/c - improved type 1-249-443-11 introduced | plamensl | 14-09-2004 |
| Sony | BE4 | No txt or OSD | R081 o/c, C810 also failed | plamensl | 14-09-2004 |
| Sony | BE4 | Pic displaced down by 2cm | Volts on Q500 & 501 way out - Jungle chip MC44007P faulty | plamensl | 14-09-2004 |
| Sony | BE4 | Reverts to st/by at sw on with 6 flashes from LED | over-current protection circuit (Q600, 602) is operating, usuallyprobs in LOP. To identify the cause, first dis FOP chip (IC501). If set switches on with frame collapse, replace IC501. If set fails to switch on, dis HT feed to LOPTx. This should give 4 flashes of st/by LED (no horizontal fly-back) showing that problem is in LOP. Check LOP comps before condemning LOPTx. If st/by LED continues to flash 6 times even with LOPTx disd, check R620 (270K) & R622 (470K) in over-current protection cct. | plamensl | 14-09-2004 |
| Sony | BE4 | Txt can't be selected - nothing happens when you try | Enter service mode, and at the "TT" prompt type "18". This will turn teletext on or off depending on how it
was originally set. Sets which do not feature teletext or have the wrong version of IC001 fitted will only display P100 when teletext is selected. | plamensl | 14-09-2004 |

| Sony | BE4 KV14T1U | Auto grey scale lines visible at top of screen | EPROM ST24C02CB1 IC002 faulty | plamensl | 14-09-2004 |
| Sony | BE4 KV14T1U | Dead | cracks in print around loptx | plamensl | 14-09-2004 |
| Sony | BE4 KV14T1U | Dead - no led lit or flashing | 0.47R resistor from the 300volts input to the chopper TX
was O/C, replace STRS5706 chopper chip, still dead - LOPTr S2055N leaky If LOPTx is grey, R806 1.5R
with a 1.8R resistor Part number 1-216-352-11. | plamensl | 14-09-2004 |
