    Hi any and all!  My skills with electronics is very limited, but as I get ready to look at my 6-blinking-lights KF-50WE610 TV (which I picked up for free, I wanted to take the chance to learn some more on testing the parts rather than just replacing them (I already have the 'Lamp-Driver SB including lamp driver removal drawings' package from JeHill- thanks!)  I wanted to try and test the thermal fuse once I get the set apart.  I have seen a couple of different ways to do this.  One is to disconnect the fuse and test for continuity- if it beeps, it should be good.  But I am curious if there are other values I should test for besides continuity, and if so, what?

    Also, I have read you can unplug the fuse, jumper the connector back to the TV, and see if the set then powers on, thus confirming that the fuse is bad.  Obviously, you do not want to run your set without the thermal fuse  Is this a valid test?  Also, while I have used jumpers many times before on computer boards, I have never done one manually- I presume, with the set unplugged for a time, you would just insert a wire into each hole, turn the set on, and see if a picture comes on?  Anything to it other than this?

    I would welcome any and all suggestions on this, and let me say 'thanks' in advance
