| Mitsubishi | CT25M2TX | OK at sw on then no osg aft 30sec. Aft 5mins blank raster for 10sec on chan change or adj Vol | If freezing field chip IC454 AN5521 works ok - chip faulty | 14-09-04 |
| Mitsubishi | CT25M3 | Slow response to front & R/C commands | Resolder Xtal on Txt panel | 14-09-04 |
| Mitsubishi | CT25M3TX | Trips at sw on - ok when LOP dis'd HT correct at 145v | LOPTr leaky - check for dry joints esp IC951 | 14-09-04 |
| Mitsubishi | CT25M3TX Euro 14 | Difficult to come on from st/by, wont stop at stations & graphics wrong | C955 2200µ 25v leaked over EEPROM IC702 X24CO4P - both need replacing | 14-09-04 |
| Mitsubishi | CT25M3TX Euro 14 | Tuning instructions | Select chan & press preset on r/c (tuning display appears in blue at bottom of display), change to yellow by pressing up/down chan. press vol +/- to start search tune, then press vol + until channel is displayed, press preset button to store | 14-09-04 |
| Mitsubishi | CT25M5B | Failure of Q552 | Order & fit AVM5KIT | 14-09-04 |
