Native video tape no matter with the machine or other video playback, the television screen on the right side is a 2 cm wide vertical red band, image without red. The failure of IC is more, the specific scope as shown in figure. The first thing to determine where failure on a piece of board. Panel B3001 and B302 is the key to determine the fault, the R (1) end, (2) to B. First turn on the two boards are removed from the machine, measuring B302 and respectively. B3001 resistance value of (1) end, according to the previously maintenance when compared with the measured data, found B302 (1) circuit. B302 with wire (1) the client and IC317 attending feet after repair. B302 and B3001 foot each resistance value shown in table, for your reference. By open circuit of B302 (1) end, just broke open the chassis, to drop out of a small screw, then watch B302 socket on the back of the plate has a flaw.wYtservice manual download site
