Question about Televison & Video
First thing you can do is pull the speaker grills off the front and
gain access to the bottom of the crts. Look to see if you can see a
faint glow from the bottom of them.Thats going to be the filaments of
the crts and will let me know if the high voltage transformer is
running or not. The transformer runs the filaments.
Power it on and put on an active channel. Look down into the crts and see if you can see a picture.
If you can't see a picture, then the flyback transformer is running but the set does not have high voltage to run the crts.There is a large red wire coming out of the flyback. It will go to the high voltage splitter that has a red wire going to each crt. The splitter could be bad. Check it out physically to see if there are any cracks in it.
If there are cracks, replace otherwise it's most likely the high voltage divider has gone bad.It is a common failure in big screens. Unless you have past experience with extremely high voltage, it would not be safe for you to work on this.
Your best bet is to replace the divider and have a professional do it.
Let me know if you have any questions
