Sorry this is not a fix but i wanted to say that i have the same problem on my tv which is the same model as yours.
At start tv would show faint parallel diagonal lines until some day it stopped working.
Everytime i try to turn it on it doesnt! and makes a ticking sound from the back of the tv.
Did you fix yours btw?
This sounds like a bad connection or a bad capacitor in the 220 volt source that supplies the voltage for the CRT boards. You will need to get a schematic and trace out this voltage from the PM board to the CRT driver boards when the set acts up. it could even be a connection on one of the plugs from the PM board to the CRT boards. Sorry but not a real easy repair. Might take some time to trace unless a component is failing. Good Luck
Make sure that all scarts and sockets are plugged in tightly. Try different inputs, try connecting a DVD player or another piece of equipment to the sockets in turn. Also, if you`ve got a sky box, remove the scart plugs one at a time and reconnect it immediately so that you know where you took it from. Check if there`s a switch on the back for external speakers, Make sure it`s switched to internal. Some of the TV`s have the switch for internal and external speakers in the menu`s. Make sure that any switches whether mechanical or electronic are switched to internal. Ian
The ticking indicates a feed back on the power supply - most likely the shutdown circuit itself because something up-circuit is shorted. MY first guess would be the HOT (Horizontal Output Transistor) - Second guess the FBT or Flyback Transformer...
I might have the service manual for that, just email me personally and make it clear what you're after. I get nearly 3000 emails a day and I be real lucky to remember what this is all about when I get the mail...
PS Go online and download Pando... It's a free download and the best way to send large and/or multiple large files over the net...
Is this a Toshiba or an RCA? The problem description does not seem to be right. From what your saying though it sounds like there isn't any high voltage. If you are not qualified to work on TVs you probably should take it to a shop for repair.
