I can't keep them straight.
That TV seems to have some HV because there is light on the screen. Obviously the sweeps are not working right. They are so wrong that it is difficult to say what is wrong. I would get the raster fixed up first. In general comparing voltages with what it shows in the service data is a good place to start. If what is on the TV CRT doesn't help much to diagnose a problem then a scope looking at the waveforms will reveal more.
Every time you install something wrong or burn something up you dig yourself in deeper trouble.
I think you would profit by leaning more how the TV circuits work.
Did you ever read at "Television Simplified" by Kiver?

If you learned not "how to" but "how it works" or "why it works", you will be able to figure out some things yourself without always asking "What should I do now?".
You are very lucky to be around in a time when such knowledge can be downloaded easily and for free. |
Sorry about the multiple tvs in one thread, but I thought it would of been kind of redundant to start separate repair threads on these 2 tvs when I already had one thread started on both of them already.
Anyways I'll take a look at that book passage you linked to in your post and see what I can figure out.
But considering I'm coming from a generation where for the most part TVs and radios were considered throw away items and because of that there was no such thing as electronics repair classes in high school or community College, I'd say I'm doing pretty good by getting to the point that I have in electronics repair by myself with the help of these forums and the internet.
