what i dont understand is what is it that they call diode side of the meter. whats the diode side?
i have a cheap craftsman multimeter. i think if im g |

Would it be simple job to replace the whole transport, if one could be found? I think it is a Phillips CDM 4, not sure which version. Information about these transports seems hard to find. A list of other players that contained it would be |

05-12-2008 | feedback sound from speakers | i have a mitsubishi vs-60609 rear projection tv i just replaced the convergence ic for a red conv.issue now when the tv is first turned on till warms up has a loud feedback humm through speaker....its always there but gets faint after set warms...any idea |
05-12-2008 | | Not sure what you mean by "diode side of the meter"? where does the article refer to that? Are you talking about how to test a diode with the meter?
Sounds like you may be getting a bit ahead of yourself. Really,not necessary worrying about M |
05-12-2008 | feedback through speakers | i have a mitubishi vs-60609 i replaced the convergence ic for a red covergence issue and checked diodes picture is back to 100% ...now there is a humm buzz through the speakers really bad till set warms then you can barely be hear any ideas???? |
06-12-2008 | | Did you disconnect a lot of the plugs? |
06-12-2008 | | If sound was Not a problem BEFORE the convergence repair ... I would suspect lead dress. :arrow: If sound issue has been there all along ... I'd start with audio power supply source(s). Usually bad electrolytic. :?: |
06-12-2008 | | I'd suspect the speakers are plugged into the wrong connector. Or there's fluid some where on the signal board. |
06-12-2008 | | ok what i want to know is a way to test the mosfets and find whats wrong on the system so i can fix it.
also want to test everything in that path so i can find the problem causing my no bass.
thanks a lot for taking the time and patience to help m |

06-12-2008 | | No intent to discourage your apparent interest in figuring out how to test different devices--the more you know, the better off you are.
However, point being that in order to be an effective troubleshooter in any electrical/electronic circuit, there ar |
06-12-2008 | | How your wires (especially speakers) are routed around/by/through areas. For example you never want to "dress" wires near high wattage resistors. |
06-12-2008 | | thanks jts..... they are ran how they were from the factory ...i did move them around to see if that was it but no luck.....do you think the convergence ic could be causing this? |
06-12-2008 | | I don't think IC's involved. You say your picture is now OK. I presume you installed the correct IC's (All convergence IC's should be replaced at same time).
DO double check all plugs and connectors (matching "AB," "CF," etc.) that yo |

06-12-2008 | | I do get the same failure. I tried by replacing the tuner twice but apparently nothing change.
Do you know where to get RK-21CC40mx schematic or any tip about this failure?

06-12-2008 | | this tv only has one covergence ic chip.....i also noticed channel 2,3,& 4 local stations have some static on picture as well its pretty bad until the set warms......but all other cable channels are great....i checked & double checked the wiring.. |
