My first TV--SONY KV 1212

Can anyone offer a likely fix (or guesstimate on cost to fix) or a connect to other forums for what has become a real sentimental Box? I bought this 13 inch SONY Trinitron KV 1212 in 1975 and it has absolutely worked like a champ. Was devestated the other day to find that it is getting power but no audio or picture, and reset switch did not help; we have had electrical storms and lost power once, and I unfortunately did not have it plugged into a surge protector (bad on me!!). From web searches have found stuff like Q601 & Q602, and H.O.T, and looking inside the box I see reference to a fusible resistor (R524); of course I am not an electronics technician so I hesitate to try anything WAY over my head, but I know how to do basic soldering, and can certainly read the circuit boards

Am I a nut trying to fix this 30 year old TV?
