KRELL PREAMPLIFIER

[xudaquan]

Guys, I bought a KRELL KRC from ebay, and now the device is plugged in, but it doesn't give me a "power on" message, only the power light is on, and any button presses have no effect. I have a certain ability to repair, but I lack a maintenance manual and don't know the working of the MCU clearly. Hopefully we can wait until the guys get a repair manual or hear from someone with experience. Thanks

各位，我从 ebay 买了一个 KRELL KRC，现在设备已插入，但它没有给我“开机”消息，只有电源灯亮，按任何按钮都没有效果。我有一定的维修能力，但缺乏维修手册，对MCU的工作原理不太了解。希望我们可以等到他们拿到维修手册或听取有经验的人的意见。谢谢

Hey guys, I bought a KRELL KRC off ebay and now the device is plugged in but it doesn't give me the "power on" message, only the power light comes on and pressing any buttons has no effect. I have certain maintenance capabilities, but I lack a maintenance manual and don't know much about the working principle of the MCU. Hopefully we can wait until they get the repair manual or hear from someone with experience. Thanks
