Mitsubishi | C21M5BT | Int start up at sw on | No line osc - R704 on SCL to micro o/c ( may be marked R703) | 14-09-04 |
Mitsubishi | CM21M5BT | dead | Q901, R991, IC901, D909, C914 & Q552 replaced. A BU 508DF or BU2506DF works in place of BU2506DX Q552 | 14-09-04 |
MITSUBISHI | CT21M5BT | DEAD OR INT START UP | CHECK R704 FOR O/C SOMETIMES MARKED R703 ON PCB | 14-09-04 |
Mitsubishi | CT21M5BT EE4 | Int loss of pic - sound still present | Invisible dry joint IC650 TEA5101B RGB o/p chip on crt base | 14-09-04 |
Mitsubishi | CT25M5BT | E/W DISTORTION, LACK OF HEIGHT | REPLACE EEPROM IC | 14-09-04 |
Mitsubishi | CT25M5BT | Sound int mutes | IC701 micro ST9291N6 | 14-09-04 |
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). | 14-09-04 |
Mitsubishi | CT25M5BT EE4 | Field collapse | TEA2031A (IC551) & supply decoupler R516 0R82 safety resistor. | 14-09-04 |
Mitsubishi | CT25M5BT EE4 | Green LED only - prev int off - HT present | No line dr from IC201, no micro activity, replace EEPROM 24C08 & set up | 14-09-04 |
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 | 14-09-04 |
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. | 14-09-04 |
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 | 14-09-04 |
Panasonic | Z185 TX14BT | Tuning absent | Replace eeprom 24C16 with new reprogrammed chip | 14-09-04 |
