|---|---|---|---|---|---|
| Mitsubishi | M5 srs | Tuning drift . Fit previous mod if not done alread | Change R120 220k to 100k , Change R121 180k to 82k , Change R126 100k to 47k remove R736 22k and fit an 8k2 & 15k 1/6w R-Met | ||
| Mitsubishi | M5 and AV1 srs | TUNING DRIFT OR INCOECT AFC OPERATION | FIT 180k + IN4148 IN SERIES FROM TUNER PINS 2 - 6 ( PIN 2 -180k->l- PIN 6 ) | ||
| Mitsubishi | M5 and AV1 srs | RGB OUTPUT SC ( IC660 TEA5101B ) | CHECK FOR 12v ON WIRE LINK TO PIN 2. IF MISSING OR LOW PICTURE WILL BE AWFUL AND A1 WILL NOT SET COECTLY. Q6E8 LEAKY. REPLA | ||
| Mitsubishi | M5 & AV1 srs ( 2 | POOR PICTURE . | REMOVE Q6E2 , 6E3 , 6E4 , 6E5 . DECREASE RED DRIVE BY '5' POINTS , INCREASE BLUE BY '3' STEPS . THIS HAS BEEN DONE ON LATER S | ||
| Mitsubishi | M5 & AV1 srs ( 2 | POOR PICTURE . | CHANGE R521 FROM 82k TO 56k AND FIT ZENER DIODE KIT , Pt No 264P45090 | ||
| Mitsubishi | M5 & AV1 srs | WHEN SWITCHED ON LED COMES ON GREEN , HT & LT PRES | CHANGE C955 TO 3300uF 35v ( Pt No 181P353000 ) EEPROM MAY NEED RE-SETTING . | ||
| 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 | ||
| Mitsubishi | EE4 (M5 models) | To enter service mode | Press & release S701 next to aerial socket, then press "9" on hset within 5 secs. Buttons 2 & 8 select adj code, buttons 4 & 6 adj data value. Button 1 cancels written data, button 0 stores data into EEPROM see article TV Jan 99 for more details | ||
| Mitsubishi | CT25M5BT EE4 | Green LED only - prev int off - HT present | No line dr from IC201, no micro activity, replace EEPROM 24C08 & set up | ||
| Mitsubishi | CT25M5BT EE4 | Field collapse | TEA2031A (IC551) & supply decoupler R516 0R82 safety resistor. | ||
| Mitsubishi | CT25M5BT | Sound, no raster | Replace Q6E7 (JC501-R) on the tube base panel (part of the spot-killer circuit). It had a B-E leak and was failing to turn on Q6E8 (2SA950-Y) which in turn robbed the 12 volt feed to pin 2 of the CRT driver chip IC660 (TEA5101B). | ||
| Mitsubishi | CT25M5BT | Sound int mutes | IC701 micro ST9291N6 | ||
| Mitsubishi | CT25M5BT | E/W DISTORTION, LACK OF HEIGHT | REPLACE EEPROM IC | ||
| Mitsubishi | CT25M5B | Under very poor signal conditions "Herringbone" pa | Fit specially screened RF lead between VCR & TV PtNo H24P001010 | ||
| Mitsubishi | CT25M5B | Failure of Q552 | Order & fit AVM5KIT | ||
| Mitsubishi | CT21M5BT EE4 | Int loss of pic - sound still present | Invisible dry joint IC650 TEA5101B RGB o/p chip on crt base | ||
| MITSUBISHI | CT21M5BT | DEAD OR INT START UP | CHECK R704 FOR O/C SOMETIMES MARKED R703 ON PCB | ||
| Mitsubishi | CT21M5B CT25M5B | Tuning drift mainly at top end of band | Add ( 180K ) & Diode ( IN4148 ) in series cathode of diode to 5V pin 6 Tuner & res to Tuning Voltage line pin 2 |
