I have a Sharp "Linytron Plus" color TV, manufactured August, 1983. I need to know what some small dials located behind the neck of the CRT are for. I just cleaned out the entire thing using frost-spraying computer duster, and Clorox wipes. I think they may have something to do with the vertical and horizontal alignment, and I need help on how to adjust them without being electrocuted.

I read something about wearing rubber shoes and keeping one hand in a pocket.

@MIKON8ERISBACK My advice it to you: Do not touch any of the controls on the CRT. These controls are for color and convergance. Its important not to touch these because once you do its very difficult to bring the TV back to normal. Both convergance and color are not an easy thing to set up with out using proper equipment and even if you do the TV will never be the same again.

In the 1990's before i knew what a HT lead was i just pulled the damn thing off! I remember hearing a loud CRACK! I went f***ing blind for two minuits,had to sit down.When i gathered myself i felt unbelievable pain down my neck,left arm,hips,left leg and it felt like someone hit me on the toes with a lump hammer! My wrist and finger were stiff where my watch and ring was too. I'll never forget that day. What a rush!

@matholton I don't know how that happened...I've touched the high voltage lead many times and nothing happened. I'm not saying it's perfectly safe but when you're working on a set many times you will come in contact with it. Maybe you touched the yoke coil ?

I've 62 years old and have been working on sets for many years.

@chrisstv1979 That's not true that the set will never be the same again, I used to adjust a lot of them. Customers would tell me their tv picture looked better when they came to pick up their set. I use a black and white picture, and the secret is to just turn the magnetic rings just a little bit at time.. but I agree it's best not for most newbies to touch these settings.

You're worried about someone else plugging in the tv or "outside distractions" causing a "recipe for disaster".. Folks, THIS VIDEO is a RECIPE FOR DISASTER!!!!!
