诊断，然后给出具体的修理费用。
功放是Kenwood VR-5090，症状是有vedio pass through 没有 audio pass through，
刚开始这个问题时断时续，后来终于彻底死菜。
以下是给的诊断：
1. The problem is a power surge. Something came from one of the other units
into the front end of the unit, electrical surges can travel through
equipment with out doing damage. At some point the surge however will go to
ground and may well jump around and damage many parts of the unit.
2.The input is an open conduit to the switch that allows you |

能保证，400刀可以弄个不错的合并甚至分体前后级了。 |
