|---|---|---|---|---|---|
| Mitsubishi | Euro 10 | Int loss of sound & pic | Check vid I/p & o/p at AV sw chip IC2A2 M5132P - if no o/p either off air or scart this chip is sus; if o/p with scart but not off air sus Q2A2. If no pic but sound ok check Q104 | ||
| Mitsubishi | Euro 10 | Int dead esp from cold | C905 220µ, C906 47µ C912 4µ7 in psu | ||
| Mitsubishi | Euro 10 | int dead (could be ok for days) | Same on dummy load proving psu fault. Opto coupler driver tr Q953 was to blame. BC547 suitable replacement | ||
| Mitsubishi | Euro 10 | HT low | Q953 JC501Q error amp | ||
| Mitsubishi | Euro 10 | Field lin faulty when cold | Glue around pins of IC501 | ||
| Mitsubishi | Euro 10 | Field jitter - int | Dry joint R461 | ||
| Mitsubishi | Euro 10 | dead psu runs | several electrolytics in psu leak electrolyte onto plug PB causing o/cs | ||
| Mitsubishi | Euro 10 | Dead - Q901 chopper tr blows at sw on | D909 3v zener s/c was the cause; also replaced R901 4R7 5w, IC901 TEA2164 | ||

| Mitsubishi | Euro 1 | Diagonal pattern of dots across screen | R914 100R in psu snubber cct o/c | ||
| Mitsubishi | EE4 CT25M5BT | Dead - blows chopper tr s/c | mod, i.e. change the 220R res on print side of CRT base to 1K2 1/2watt,this apparantly prevents a surge from blowing the chopper at switch off | ||
| Mitsubishi | EE4 CT25M5BT | Chopper Tr blows aft few days | Replace Q901 (chopper), R901 (4R7 10W), D909 (3V Zener) and change 220R resistor on the print side of the CRT PCB to 1K2 1/2 watt. | ||
| Mitsubishi | EE4 CT21M5BT | Reverts to st/by aft 15mins with a sqeal | HT was too high at 137V, due to R954 (120K in this set) going high | ||
