Good afternoon dear, I have the following problem, disassemble the CD tray to clean the connections and the laser ... (my equipment is Panasonic and has two modules SU - CH 40 and the problem is the SL - CH 40 ) When wanting to reassemble it does not add up to anything and I find it almost impossible to reassemble it correctly. If anyone could help me I would greatly appreciate it, in advance thank you very much.
