I thought I'd install a thread here about the CT100 I picked up from the ETF
two weeks ago. The restoration log thread is in the technical forum.
This morning was the big one! I installed the yoke and purity coil
on the CRT, and put the chassis in the cabinet, and attached wires.
At 8:10 this morning I turned it on. No nothing. I hooked my scope
up to the set attached to the red CRT drive ... noise only. I thought
maybe it needed a signal, so I turned on my RF generation system.
Still no nothing. I tried brightness , contrast, and screens, no nothing.
I tuned around and didn't find a TV signal ... but a bit of noise appeared
on the scope and a bit of blue light on the TV! A quick change in AGC generated more blue. First picture, 8:19 AM. Still no signal on scope.

My Sony Watchman showed
no signal either: the video to the modulator was plugged into the DVD player,
not the STB. Fixing that resulted in a picture on the Sony.
Tuning various channels on the CT100 found Ch. 10 on Ch. 13
(I had set the knob wrong). This was at 8:27.

The progress from there is shown in the pictures below, just
adjusting the full set of controls available on the front and
the focus.

The vertical hold was off.

The fine tuning was off.

The images being sent from the station were rather, ah, odd ...
the 55 inch LCD TV looked only a little less strange. Yes, it was that green.

All it took to get a good picture was a teeny adjust of Hue.
Oh yes... I forgot to make sure the audio was working before installing
the chassis in the cabinet ... its dead, so I'll eventually have to remove
the chassis and fix it.
That's rapid progress. It'll probably slow down a lot from here. But that
last picture was actually watchable.
