| Sony | FE1 KV25K5U | Trips off with a crack - LED flashes 5x | CRT faulty | 14-09-04 |
| Sony | FE1 KV25KSU | FRAME IC HOT LINES ON SCREEN | REPLACE C506 0.01MFD | 14-09-04 |
| Sony | FE1 KV25X5U etc | Enters search mode as soon as its switched on | replace SS902 preset search switch and clean PCB that it is
mounted in | 14-09-04 |
| Sony | FE1 KV29X5L | Stuck in standby with two blinks from front LED every few seconds. | Replace L.O.P transistor 2SD2539. S/C due to poor soldering of
scan caps on collector. | 14-09-04 |
| Sony | FE1 KV29X5U | Vol OSD perm displayed & front controls give wrong functs | Leaky front control switches - can be cleaned with luck/care | 14-09-04 |
| Sony | FE1A KV25FX20D | St/by only - flashes twice (prot mode) | IC606 STRF6654 low res of 140R between pins 4 & 5 (should be 3M) | 14-09-04 |
| Sony | FE2 | Line tearing, ragged verticals, arcing noise. | incorrectly fitted EHT lead at the LOPT end. Follow bulletin reference TV05900 for correct fitting. | 14-09-04 |
| Sony | FE2 | Reverts to st/by at sw on with 2 or 5 flashes from LED | 5 flashes indicates an AKB error (Grey Scale Correction). This is normally due to LOP shut down & there is no EHT or sec line volts. Normally due to faulty R618 (270K ohm). This res is in the current sensing cct & could therefore potentially give you an over-current error (2 flashes). | 14-09-04 |
| Sony | FE2 KV14LM1U etc | LED flashes 5 times - sound but no pic aft initial EHT rush | R618 270k in current sensing cct - roughly centre of board close to Q602 | 14-09-04 |
| Sony | FE2 KV32DX40U | Dead- no st/by 5v | Q601 2SA1037AK U/S on A board. Part No 872902649 | 14-09-04 |

| Sony | KD28DX40U KD32DX40U | tuning options in the menu are greyed out. | After initial installation, analogue & digital chans can be tuned together by pressing & holding auto-tune button on set's control panel (bottom right). After choosing not to adjust the picture rotation, press OK to commence auto-tuning. If only analogue or digital systems need to be tuned - select appropriate mode (analogue or digital). Analogue chans can be tuned in normal way through menu (not greyed out in analogue mode). Digital chans can be tuned by pressing i+ on the remote, then selecting blue SET-UP option, & finally selecting AUTO TUNING from menu. | 14-09-04 |
