[QUOTE=bandersen;3061508]Nevermind, I'm just being dense I had to remove a few more screws to disconnect the back from the PCBs and it came right off.
Yes, the fuse is blown but not blackened. It appears to be a odd value of 6.3A. I'll hunt around for something similar. No signs of bulging caps or any fried components. I'd try a fuse and see what happens! It is an odd value. It must be that heavy duty degausser that has that high of an inrush current. Unplug the degausser and put a 100 watt lamp across the fuse holder as an alternate proceedure. Good luck. You're going to need it! |

I've seen a bunch of that series do that. The guys at Panasonic told me the deguass thermistor passes too much current cold, stressing then eventually killing the fuse. They gave me a new part number which I forgot years ago. I've been using the thermistor RCA used in their CRT sets, but I can't seem to remember the number for that one right offhand. Never had a callback. You can tell it doesn't pass as much current though...the turn-on thump isn't as loud.
Just remembered the RCA number....207768 RCA had the same problem with some of their very last CRT sets. They also said to change the thermistor to that number Last edited by Geoff Bourquin; 02-09-2013 at 02:13 PM. |

Maybe all it needed was a new fuse like mine did ? |

Short duration overloads like the heavy degauss current have a tendency to weaken a fast acting fuse, as said before.
I know that it isn't a good policy to use a slow-blow fuse for semiconductor equipment. It's the same reason, they don't use circuit breakers. Seeing your first pictures from May of 2011, showing Korean food. Refering to the fourth picture! |
