| Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
|---|---|---|---|---|---|
| Ferguson | TX92 | After replacing the line output TX the set still appears to be tripping | Try switching the set on with the remote control. The micro seems to remember the tripping state, the remote control re-setting it | ||
| Ferguson | TX92 | Dead, No LED, 2.5Amp fuse O.K. Some voltages present at BP02 ON/OFF switch connection. 160v at terminal D of TP16. 26v, 200v, 13v lines all zero | Replace TP16 P6NA60FI and diode DP17 BZX55C15 | ||
| Ferguson | TX92 | Field fold-over / flyback lines visible at top of screen | Capacitor CF30 47uF, 50v | ||
| 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 | ||
| Telefunken | TX92 | Initial rustle of high voltage then nothing, goes to standby, same with remote or front panel controls | R12 burnt out 0.22ohms, replacing this plus the IC01 vertical IC TDA8177 got set working. NB: also check D01 for shorts | ||
| 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 | ||
| Thomson | TX92 28DT73H | Reverts to st/by aft few mins | Dry joints pins 1 & 2 LOPTx | ||
| Telefunken | TX92E | dead except led pulses from bright red to dim | In child lock mode - reqs remote to remove | ||
| Telefunken | TX92 MR702 | St/by only | TP60 BC558 s/c, IP AN25TV, CL24 510nF o/c, ZL12 cp in 26v supply o/c | ||
| Goodmans | TX92 GD2880B | Impurities due to degaus triac not triggering | Change RP40 from 1R to 2R2, CP40 from 470µ 6v3 to 2200µ 16v | ||
| Goodmans | TX92 GD2880B | Fishnet/herringbone patterning on certain chans | Fit good quality RF downlead/flylead | ||
| Goodmans | TX92 chassis | Hotel mode (no tuning menu) - to unlock | ) turn TV in to standby from remote 2) turn power off from mains on/off switch and wait until led goes off. 3)hold standby button on remote control and power up from on/of switch hold standbye button for about 10 seconds then de/active hotel lock. | ||
| 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 | ||
| Goodmans | GD2580B TX92 | Installation menu entering | Sw TV to st/by then sw off at mains. Sw on TV whilst holding "P" button in on front until Lang menu appears | ||
| Goodmans | GD2580 TX92 | Int dead | dry joints CP13 1nF5 1.6kv | ||
| Goodmans | GD2580 TX92 | E/W settings different at sw on & int reverts to st/by | IF02 STV2145 |
