I recently came accross that beautiful Sony TV 9-304UE in absolutely perfect shape with cover and even the user manual. Finally an opportunity, to watch the old tv test cards the way it should be - particularly the very old Swiss testcards I reconstructed quite some time ago.

I am somewhat skilled in repairing old electronic stuff, but not THAT skilled...
After visual examination of the internals, I switched the TV on. Sond and horizontal deflection is ok so far, just the vertical deflection is shrunk to about 1 cm height. (picture visible) I know a little about that defect. I managed to get a fairly readable circuit diagram, but NO service manual.

The only visible defect is that interesting resistor, obviously blown, 630 Ohms I suppose, the ONLY one with silver cap (10%??) I also never encountered these vertical resistors. Furthermore interesting: Its soldering points on the back of the PCB are marked with a blue felt-tip. I also cannot see where it belongs to in the circuit. Appears to be the deflection...

Questions:
- Does anyone have or know about a service manual of this TV?
- That blown resistor, I guess, it is just a normal resistor. Is there anything special about that vertical form?

Thanks for any help.

...actually not switching it on anymore before first repair attempt - no example of the actual picture size. Hor = ok vert = about 1 cm height.
