Hello to everybody.
For first, sorry if I make errors, my english is a little rusty...
I'm from Italy and I have a passion for vintage.
Often I buy defect items and with patience, I try to make they as new (almost...)
Now I have a problem.
Some time ago, I found a curious Kenwood HM-DV7 system, composed of a DVD/CD/TUNER unit, a strange tri-aural speaker and a little subwoofer.
It works fine, except for audio CD. The behaviour it's very strange. The player read disk, but tell "NO PLAY", as if the disc is a format don't recognised.
I thought may be a problem with pick-up, so, armed of service manual and oscilloscope (I'm a technician), I've checked the healt of laser.
No problem.
On service manual, there is no mention of this message, the unit seems to forgot how to read a simply audio CD. Same thing also with original or mastered discs.
No problem with DVDs (parameters are very well, this unit has worked little).
Does anyone have idea of what could be the problem?
Thank you for your help.
Greetings from Italy
