Hello,
I am working on my least favorite chassis - PTK169PGB. I have only worked
on 2 of these, and hope I don't see anymore! It came in with shorted HOT,
and after replacing all of the normal parts I have determined the chassis
will power up if I remove the HV anode lead from the HV splitter. The
horizontal signal to the flyback looks good then.
Question 1 - What is my next step to determine the defective part? Do I
remove each anode wire from the HV splitter one at a time, including the
focus / screen control block?
Question 2 - When I look down into the crt's, I see dust, dirt, dead
insects, etc. How do I clean this without affecting the crt alignment,
etc.?
As you can tell, I have never worked with projection tv crts. Please be
kind!
Thank you, any assistance will be greatly appreciated.
