Panasonic SA-HT75
Hi,
Player is seems to be working fine but after a while the player goes erratic and some capacitors on the dvd board are very hot. Also Q703 and 708 are very hot then. I guess a supply voltage is too high. Voltage on a 2,4 v capacitor is 9v(?) Also the cooling fan is not working. Any ideas? I don't have schematics. Thanks |
