Question about Televison & Video
there will be an I.C. with a part number that probably starts with an LA_ _ _ _ . It will be on a heat sink and be in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at nte.com get a diagram of its pinout to find what pins the power and outputs are on.
