If it slowly gets better with time its another sign the CRT is weak

Hi Electronic M and Zeno and all VK........

I agree Zeno .I think the CRT is done.Years ago as I looked at this set and said then the CRT is shot..Maybe the note came off but I got to put notes and dates on this stuff I check.

Electronic M .I'm not a member at RM .
Dont donate manuals and or refuse to be a member of Radio Museum because I'm not a fan of their no share policy there .They let you download a few pages a week for free and thats how I got the 2 pages of the TV Schematic..

My favorite schematics and service manual source is https://www.sharefx.com// Nice people there. Free membership and free downloads up to 100 service manuals daily..Make a request and if they have it .They will upload it for you........................

I do have a couple 7 inch Sony's here.I could check if its the same CRT and even see the TV-770 chassis is OK.I think they are the TV-720's .I'll be looking at the TV-720's soon anyway and probably post about them in this small TV forum.... .


Thank you both for your input...
