| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | FE-1 KV21X5U | burst of EHT then shuts down with LED flashing error 2 | regulator IC603 SE135N (874992061) | ||
| 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 | ||
| Sony | FE1 | Snowy pic & tone on sound | IC001 micro faulty | ||
| 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. | ||
| Sony | FE1 | Dark pic | The ABL circuit is operating incorrectly. Replace R516 (56K) & R517 (10K or 27K depending on CRT) | ||
| 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. | ||
