Sony KV-M2151D turns black & white only
hello,
my Sony KV-M2151D color television has the annoying problem at the moment that it looses its colors after it has been turned on for some time. a while the color starts flashing and its a half half situation but within some minutes after that starts it turns totally black and white. it stays like that until it gets turned of for some time, but then again it happens after some time. is there something i can do about this or is the tv at its end? thanks, bart |

This set uses the Sony BE2A chassis, and this fault is usually caused by trimmer CT332 going faulty. You can clean it or replace it with a 15pF capacitor. Failing that, check the IF section for dry joints. |

moment that it looses its colors after it has been turned on for some time. a while the color starts flashing and its a half half situation but within some minutes after that starts it turns totally black and white. it stays like that until it gets turned of for some time, but then again it happens after some time. im not that much of an electronics wizard myself so i have a few follow up questions. This set uses the Sony BE2A chassis, and this fault is usually caused by trimmer CT332 going faulty. You can clean it or replace it with a 15pF capacitor. is from trimmer CT332 the CT332 part the code on the board in the television or is that a general type or such? as for the cleaning part, how can i clean such a thing, is there more then i can do then blow a few times at it? Failing that, check the IF section for dry joints. i take it you mean if have to check something for components that might be loose, but what is the IF section? thanks, bart |

Opened the case, saw about half a pound of dust bunnies, blew the dust out with shop air, and couldn't get the problem to repeat. If you try this before going the 'qualified tech' route, be careful not to touch any part of the board(s) or tube. Just remove the cover, spray out the dust daemons, and replace the cover. Even after the power is removed, several thousand volts lurk within. Kalo |
