Sony FE2 Chassis (Service manuals – two versions)Remote RM1945APower. 1. Eleven flashes. Indicating, (perhaps) loss or reduction of the 8v supply. Actually the main power supply had failed completely, the clue being that there was no initial rustle of EHT. So, naturally no 8v supply. The cause was quite basic; the two FETs in the power supply had failed, together with the surge limiter R603 (0R1). The sub power supply was O/K hence detecting the lack of the 8v.2. Eleven flashes – no HT start up feed to drive chip OK – replaced MCZ3001D3. Eleven flashes. Intermittent switch off, or difficulty in getting set out of standby. Eventually with the help of Sony Technical C641 (470m 35v) was diagnosed with an ESR of 38 Ohms.4. Eleven flashes. Again not the 8v supply, but the power factor choke was O/C.5. Eleven flashes. Dry joint at the drain of the upper chopper transistor in the P/S.6. Eleven flashes. D624 (D1NL40-TA2) S/C. Replaced with UF4007.7. Five Flashes. Protection mode (unstable AKB) R608 (270k) was O/C.8. Dead because the standby power supply had failed. It comprises a TOP209P IC and a (tiny) little transformer that delivers 5v to the 3v3 regulator. The 5v rectifier (1NL20U-TA2) was O/C. In another case, TOP chip and R627 (4R7) O/C.9. Dead. Green LED lit and Red LED Flashing twice. R618 (270k) O/C in the power supply10. Four flashes - (no vertical synch) Replaced Jungle chip IC001 and EEPROM. Now severe trapezium distortion and picture far to high not adjustable in service mode. Removed CN1701 to the velocity modulation board - OK. Replaced connector - still OK. Suspect dry / S/C on pin 1 of IC902.11. No sound or picture with the Green LED lit. R610 (330k) replaced. 12. Set dead. C005 (1000/6.3) S/C13. Dead set. D628 (P6KE200A) S/C14. When put into standby the 135v line remained high but the other voltages were switched off. As a result there was increased current via R5056, R5048 and R5068 giving reliablity problems. Check value of R6019 on board ‘A’ If it’s 4k7 replace it with a 1k chip resistor.

Line. ( Use BU2515DX – others can run hot ) LOPT NX-4521-Z = HR8579Spares LM393DT and IRF614 - Wiltsgrove at £2.95 and £3.95 +V1. Dead set. Q533, LOP (BU2515DX) S/C. When replaced, front LED flashing twice (over current problem. R618 (270k) in the over current network, high in value.2. After LOPT (HR8579) and LOP (BU2515DX) replacement, Picture regulation changed with brilliance. Check R516, 517, 518, 510, 528 and 5293. Dead, apart from LED flashing twice. Over current protection. LOPT and LOP.4. Bright raster with flyback lines. LOPT faulty.5. LO/P S/C and LOPT duff. When replaced, picture was small, in the middle of the screen, bright with incorrect RGB drives. Thoughts were towards the EEPROM but advice re-directed to the Micro-combined-Jungle-chip, an 80 pin SM device (TDA9394H-N1-5-0423). When replaced only the tuning had to be reset.6. Eleven flashes, LOP duff. Replaced LOPT anyway then got two flashes (over current) found FOP STV9379 S/C replaced FOP set then functioned, sound OK but brilliant raster with flyback lines. Found that RGB HT was OK but A1 wouldn't turn down. Self made fault - I forgot to solder the bottom end of the focus / A1 chain pin on the LOPT Fool.7. Poor E/W after LOPT change (usually) R518 (2k7 SMD) pin 11 LOPT goes O/C.8. Width jumping in and out. Small panel (Board D2) Q8801 replaced.

Field.1. Two flashes and smell of burning FOP chip after LOPT and LOT change, STV9379 replaced.

Picture.1. Sound but no picture at switch on, led flashing red and green continuously. Picture comes on with channel change. Check A1 setting.

Service modePress OSG, 5, Vol+, TV. Then press Menu. After adjustments exit pressing Menu then switch set off.

Control. 1. Would not respond to RCU although the LED flashed on command. Sony suggest pressing the TV button, because the set could have entered the ‘Ageing mode’ This entered by keying TT07 in the service mode.2. Didn’t capture any stations on self seek mode. When the Technician menu was called up some of the settings were found to be incorrect, also in the self-diagnostic display, the tuner failed to answer when the control chip called its name. Replaced tuner and re-programmed.
