Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Ferguson | TX92F | Set tripping with led flashing on / off | Most likely to be RL08 a 10K smd resistor connected to pin 8 of the LOPT. In every case i know of the LOPT also needed replacement HR7360 | ||
Telefunken | TX92F | Keeps on burning the surge resistor 280ohm 5W in series with the chopper transformer | Replace the chopper transfomer it has a short either on the primary or secondary side | ||
Saba | 615 TX92F | At startup, synchronisation vertical as well as horizontal is very weak, after max. 15 minutes everything is ok. Sometimes there is no picture | First check all capacitors in the power supply. The real problem was spotted in the IF-area, the shielded space near the tuner: replace all capacitors there, especially the 2.2uF/100 volt type. I replaced it with a 3.3uF/100 volt type with excellent results! | ||
Telefunken | TX92F | Dark picture | Replace RL03 | ||
Thomson | TX92F | LED flashing at sw on (prot mode) | disable pin 4 of IP 70 IC TDA8139 to over-ride prot cct - shows field coll; IC STV2145 (IF02) was faulty, but still no functs - replaced EEPROM - now bad col with green flashes - jungle chip faulty | ||
Goodmans | GD2880D TX92F | Reverts to St/by aft init EHT rush & brief green LED | TL41 BD681 (s.c.), RL47 3.3 ohms, DL21 BY228 ( S.C.), 1.5uF 160V.W. capacitor (o.c.) | ||
Goodmans | GD2880D TX92F | Int reverts to st/by | Dry joints CP13 in snubber | ||
Ferguson | TX92F T59NB | St/by only with flashing led | LOPTx & RL08 10k sm under loptX | ||
Ferguson | TX92F T59NB | Field foldover at top | CF30 47µ 50v between pins 3 & 6 of FOP chip IF01 | ||
Ferguson | TX92F T59NB | Dead sm resistors burnt up under LOPTx | RL07 3k9 & RLo8 10k sm under Loptx & replace LOPTx that caused the fault | ||
Ferguson | TX92F | Switches off aft 5 mins | Change white opto coupler IP60 4N25TV for black type (same no) | ||
Ferguson | TX92F | Dead | RP08 270k ½w o/c |
