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...

Service tech opens your set, sees a black cat....."Well THERE'S yer probbblemmm!!"

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

didn,t find any notes on my schematic.
is your service switch contacts CLEAN |

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 |

thanks for info.service contacts are clean,transistors are good.i checked them in another set.have to get moving on this.it is my daily watcher in the garage and i spend more time there than i should!i will keep you posted on progress.nib doesnt mean much after 38 years in storage!

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.

i ll take it, bryan.i was out at devry yesterday and they have every sams that has ever been printed,except the ones for early to mid 70s xl100s.looks like someone else had an issue with these sets.

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: |

i tried the module in my other set.its good.transistor are good also.i will try the yoke this week.set is a ctc 58 chassis.i can use that scan.thanks to all!
