I got an old CRT TV the other day somebody gave me. I saw something online about cutting the HV horizontal coil, and moving the vertical opt to the horizontal coil. Then using vertical coil and hooking an amp up to it and applying input to amp. I tried using an external amp connected to radio, but all I ever get is a dot in the center. what I understand there should be a line. They adjusted something to do with the scanning frequency I'm thinking maybe that is the issue, but i'm not seeing this on mine.
Mine has the following internal adjustments on the main board:
vlt-adj, h-con, RF-AGC, V-size, sub-bri, V center.
I don't really have much idea what any of them do. I looked online, but hard to find anything about crt repair now. From sounds of it I would guess either be RF-AGC, or sub-bri, but mine may not have this either. The rest i'm thinking are for size, positioning.
they used an analog style tuner/volume unit, mines digital control. not sure makes a difference, but I wouldn't think since mine makes blue screen if no signal so should work.
The instructions i'm using are: http://www.instructables.com/id/Ful...illoscope/step5/Horizontal-Frequency-Locking/
