Hello Humphrey,
This is Winston from Barbados. I've bought your book CRT TV
Repair and I am getting through quite well because of how well the information
is presented.
My problem now is that I have 2 TV's that were showing Red only, and one that was showing Green only. I was able to get proper color restored, by re-soldering dried joints on the CRT neck board, but now all the TVs (27 inches, different brand names) show too dark screen.
When I make adjustment at Screen pot at back of FBT, the picture gets brighter, but retrace lines appear, and/ or the picture rolls vertically. I've measured about 4VAC at Heater terminal at FBT at each TV.
I don’t know what to do next. I need help because my friends are telling their friends that I am the greatest TV tech they know...
