Ok spot killer is on so I wanted to double check the chassis mounted transistors.
I put the meter on diode function then I proceed to test.

Ok I put the positive on the transistor and the negetive on the chassis and no beeps.Also im getting a 1401 number does this mean anything?

Then I put the negetive on the transistor and the positive on the chassis and I get a beep.I pull the meter wires off then I get no beep put it on again and I get a beep.The beeps are not consistent thats whats screwing me up.. Also Im getting a 584 number in my eyes thats just telling me that its testing the transistor and that I have a short.

Thanks in advance for any help you may give..

If the beep is quick and then the number starts counting up, you are reading a cap in the circuit. If you want to get an accurate reading, unplug the connectors from those transistors to the deflection board first...

Does it matter where the probes are on the transistor? + or -

Thanks for all your help modessitt :)
 
It depends on whether it is a PNP or NPN transistor.

Check this page, about halfway down, on reading PNP or NPN transistors:

And a quick check of which type transistor you are checking can be found by searching for the datasheet online.

For example, if you're checking a 2N3716, it's an NPN transistor. If you're checking a 2N3792, it's a PNP transistor...
