IIRC there is a black & a yellow pot near each other. One is
V size the other 90 volt adjust. I THINK the black one is vert size. For buzz be sure the tuner is in the right mode ( air & normal AFC ). If its a light buzz you can try the audio detector coil but be sure you can go back to the start if it dont help. BTW I bought one of these new & ran it a few years. They gave an excellent pix. If your control door isnt broken off its a miracle. They all did & as careful as I was mine broke. I am going down Maine friday. When I get back I will see if I got anything on the set. 73 Zeno LFOD ! |

Zenith 25"
I have the 25" version of that TV. Can't find good service information. I don't know how to properly set the 3 Screen controls cause there's no service switch. Sometimes it takes a two or three seconds before the power supply starts and the high voltage pops on. Also Photofact has nothing about convergence. Is there a place to get good service information to get this right again. It was handed down from my Grand Father.

If it has a 9-160 main board it HAS cold joints on it.
They all did over time, thats 99% your start problem. If it uses 9-214 main board there is no grey scale, its automatic. On 9-181 main & 9-155 CRT socket sets grey scale you can 1) turn all three colors down. 2) one color will be dominant, raise the other two to make B&W. Convergence cant be described & I never understood it to be honest. The rear magnet is purity, the others center conv. Mark them & play with them. Some had a locking ring in front. Some used twist knobs & others tabs. Side conv is by bending & wedging the yoke. Early EFL sets used a yoke ring with adjustments. 73 Zeno LFOD ! Quote:
