TX92 Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| TELEFUNKEN | PALCOLOR F430 NIC CH. TX92 | Mat only starts for 2´´, led loses brightness and +b drops from 113v to 80v | Dl21 by228 with leak and rl47 of 3r3 open. | ||
| 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 0.22Ω, 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 tsound 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 tsound, 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 | ||
