Power supply does not work, fuse blown, c607 shorted. (before maintenance/resoldering, the power supply was working or tsound was no short on the c607) | The technician must be careful with all circuits with strw6556a like the one on this TV, as the capacitor c607 (220uf/400v) is not automatically discharged by the str, even after several hours it may have some energy in it. | Discharge the capacitor before resoldering the str. If you forget to discharge and the fuse blows, if the c607 has a short circuit, remove the str and check if the short circuit has disappeared. | R |
