You can suspect the deflection yoke also for shorted winding. If it doesn't overheat, you can remove it later. You just put a small heatsink to it and check. Usually samsung sets use no heatsink for the horizontal output transistor. Replace the yoke return capacitor, 0.33uf or so also. Hello You just replace the freewheeling capacitor, normally come up to a value of 5600pf 2000V or so, connected to the collector of the horizontal output transistor, fitted very close to the collector lead. Do a search by type in the brand name of your device at its search box. Viewing it in ' Mosaic' or ' Magazine' will make surf easy. If you wish to get some details check the site linked here. You have to find out the exact reason for this. If the base pulse width is abnormal, this might happen.
