You know about this, but do be careful that your kitty cat doesn't go noseing around the chassis when the TV is powered on. And cats like to rub their chins against various objects, hopefully not objects carrying high voltage...

fixed one years ago for the same problem seems like a resistor opened it was on the circuit board with the mak and mal & video out boards. steve

i am almost sure i circled the bad resistor in the schematic. i will look tonight or tomorrow for that schematic. i believe it was a resistor off the video line. it ran me in circles which is not hard to do anyway. lol steve

i did not finish before the post uploaded ??
anyway check r609 33k r620 820k on the circuit board with the service switch
magoo1 voltage pinouts
pin3 ground
pin 4 30.6v to sweep
pin 6 31.6 to sweep vertical output transistors
pin 7 8v to height control
pin 8 30.6v
pin 10 83v b+ in
pin 127.90v v sync
maybe this will get you started in the right direction
steve

Ron, I'm not sure that I have a Sams but I should have a factory manual for it. I'll mail it to you if needed.

Check the exact chassis number, there should be a suffix. The Sams index lists two different versions and I suspect the factory manuals break it down further.

The tripler failed so you changed it now you just have a vertical line? Thats an interesting one....
The output transistors may be good but one of the small ones on the module may have failed. I have seen that in the xl100s.

If you need a scan of the vertical circuit i can do it in the morning?:smok e::y es:
