Help with repair of 6 disc CD changer for a Nissan Frontier 2001
I have a Matsushita 28185 9Z600 CD 6 disc player from my 2001 Nissan Frontier. It also has a Ref No. CQ-EN8060Z and I really need help with the mechanics of this unit. My 6 year old grandson knocked it off my workbench and a part flew out of it and I have no idea how or where it fits in. I think it is the thing that moves the CD's in and out because it opens up and closes back like it is designed to grab and hold something. Has anyone ever taken a similar CD player/radio apart? It looks so simple but for the life of me my brain just will not solve the puzzle. I have never been good at doing puzzles anyway, the pieces all look alike. Thanks for any help in advance. Please stay safe during this pandemic. Ralph         Coinhunter@Charter.net

Mi lenne ez a BQ=W , mivel helyettesíthető.? Én nem találtam.
Köszönném ha segítene valaki.
 
Leyland AM/FM Car radio - no FM

This radio is to a 1970's MG/MGB vehicle. Its using an older 14 Pin DIP IC to
do the FM stuff, its marked T2D. Cross ref comes to a NTE723.

If I put my metal probe on pin 9 or 10 (detector) I can hear a local FM station playing,
but the tuning has no effect.

I have 100 ohms from pin 9 or 10 to gnd. Pin 3 is seen directly tied to gnd, and pin 4 also reads short to gnd
and there is no DC volts on it also no dc volts on pin 5. I can see no dc volts on any pin I probe. Is the IC bad?

Its not getting warm for short and current draw on the PS is minimal.
