Hello everyone, I'm repairing a v8000 beocord that suddenly the video and audio disappeared, you can only see the writing at the bottom of the command menu. When I turn it on I hear the hiss of the tuner then when I insert the cassette only the black screen appears. I've changed all the capacitors except on the power supply board which seems to work fine, cleaned the heads with a cassette cleaner but nothing has changed. Has anyone had the same problem? how did you solve it?. Thanks friends
