Convergence IC392-110 =? NTE7178?

[d0ngta0]

Minnie,
What is the purpose of the coolant? When and the purpose of changing it?
I would really like to understand this TV better so can I ask for you help with getting schematic for it? Is it possible to PDF it? I would really really appreciate your help. And if that's not possible, what schematic do you have that is closest to this tv?

Help..

The coolant is in side the tubes. Glycol alcohol. Think of a radiator for a car. Theres a chamber in the tube when it gets too hot the coolant flows into it to cool. There's no need to change it unless it's a Phillips tv and slime builds up.

Minnie and All,
Good new: After I change the STK392-110, it fixed my PowerOn/Off problem. The pictures started to work again. So now I know it's the convergence chips. Thanks to this forum and Minnie's help. I really appreciate it.

Bad New: After about 1 day of used, the color is now getting more green and more green. Does this mean that the convergence ICs are going back on me again?

a. Where is a good reliable place where I can buy good original STK392-110?
b. Someone suggest using STK392-150? Is this better than the 392-110? What's better? I can not find any specs on it?

Thanks ahead.
