Sony | FE-1 KV25K5U | Int reverts to st/by with LED flashing 5 times | CRT internal s/c - replaced under guarantee - very prone to this fault apparently | 14-09-04 |
Sony | FE-1 KV25K5U | lines across screen, frame IC running hot | C506 0.01 uF | 14-09-04 |
Sony | FE-1 KV25K5U | not starting up, LED flashes 4 times | T511 breaking down at switch on, replace T511 (145326411 for 25", 145326511 for 29") | 14-09-04 |
Sony | FE-1 KV25X5U | comes on then goes off, red LED is on | stby IC609 TOP209P u/c | 14-09-04 |
Sony | FE-1 KV25X5U | yellow line down screen about 2 inches from RHS | IC301 CXA2060BS (875208838) | 14-09-04 |

Sony | FE-1 KV29K5U | dead, in stby | C515 220uF 25V s/c | 14-09-04 |
Sony | FE-1 KV29K5U | no remote operation | D907 BZX79C9V1 leaky on SIRCS line | 14-09-04 |
Sony | FE-1 KV29K5U | pink band on LHS, only obvious on dark bachground | video lead from CN504 on A PCB to CN704 on CRT wrapped around L537 (LINE LIN), tie bottom edge of loom to the hole provided in top right corner of S PCB | 14-09-04 |
Sony | FE-1 KV29X5U | no remote, front buttons are Ok | D908 9.1V zener leaky on H board | 14-09-04 |
Sony | FE1 | Buzzing only on sound from tuner - ok on AV | Incorrect sound system selected, the cause being memory corruption. To correct the problem, enter test mode to obtain "TT - -" on screen, & type in "24". This will reset sound system back to PAL I. Turn set off & re-tune, & sound should then return to normal. | 14-09-04 |
Sony | FE1 | Dark pic | The ABL circuit is operating incorrectly. Replace R516 (56K) & R517 (10K or 27K depending on CRT) | 14-09-04 |
Sony | FE1 | Reverts to st/by at sw on with 2 or 4 flashes from LED | 2 flashes indicates an over-current error in line stage, & 4 indicates a frame fault. However, quite often, when 4 flashes occur it can still in fact be an over-current error as well as a frame fault. To prove which is the correct fault, measure pin 52 of the micro (IC001) at switch-on, and if this voltage goes high (anything above 0.6v) then it is in fact over-current. If it stays at 0v then the fault is more than likely within frame stage. | 14-09-04 |
Sony | FE1 | Snowy pic & tone on sound | IC001 micro faulty | 14-09-04 |
Sony | FE1 KV21X5U | Dead with 2 flashes from led | When D512 was unsoldered, LOP stage operated - Q703 (BF420), Q704 (BF421) and Q713 (BF420) all in the red output. Plus D701
(MTZ J 5.6B, a 5.6V zener) leaky and D705, 1SS133T (1N4148) O/C. all on crt base | 14-09-04 |
Sony | FE1 KV25K5U | Dead with LED flashing 4 times | Check for 9v at pins 33 & 34 IC301. If present, check R546 47R 1/2w for o/c (135v Line dr supply) | 14-09-04 |
Sony | FE1 KV25K5U | No R/C op - hset ok | D011 5v6 zener on o/p of Rx leaky | 14-09-04 |
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 |
