MitsubishiCT2627Sound increases - oscillates.Bad connection on audio plug FF.
MitsubishiCT2627NO SOUND OR COLOUR + WON'T GO INTO STBY BUT WILL CR7N5 OC IN 12v REG FEED MAY BE REMOTE IC SC ( SAA1030 ) I THINK !!
MitsubishiCT2627No sound12V supply to IC 301 missing caused by C305 330uF 25V s.c. In SIF section.
MitsubishiCT2627Frame -height varies & int frame collapse.C412 , C413.
MitsubishiCT2607Field collapseo/c wire on scan coil loading coils
MitsubishiCT25MSTX E14 chassisDead - st/by led lights briefly at sw ondry joints on IC951. Drys were also found on regulators IC952, IC954 & IC955.
MitsubishiCT25M5BT EE4Green LED only - prev int off - HT presentNo line dr from IC201, no micro activity, replace EEPROM 24C08 & set up
MitsubishiCT25M5BT EE4Field collapseTEA2031A (IC551) & supply decoupler R516 0R82 safety resistor.
MitsubishiCT25M5BTSound, no rasterReplace 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).

Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
