My Trusty old TV no longer has a picture... 
I switched it on recently and got the sound but no picture.
I have googled around and checked out all posts here and found that there are 2 possible causes:
If the picture comes on after about 20 Mins its the jungle IC
If there is no picture at all then a few components need replacing as follows...
D505, C416, R409 and R503. Check D506 for good measure...
Now Im OK just replacing these as they cost pennies each but I cant identify what value D506 is! I know its a Zener but need to know what in order to replace it! 
Can anyone here cast any light on this or any other diagnosis?
Ive been looking round for some of that old TV engineers database / Diagnostic software for ages but just cant find any for download.
Thanks in anticipation

Since Posting this, I resoldered the joints on the above parts which fixed (for 1 hour) the problem. Now I have a vertical bar from top to bottom of the tube in the centre. Can anyone cast some light on this as I cant find information on this!
Thanks again...
