No lights or responce (power issue)

There are 2 internal fuses. One of them (F1, 250mA) does randomly fail causing a dead deck. It is easy to change - it is on the mains power input circuit board underneath the platter and black plastic cover.

If your fuses are unresponsive after replacing, or do not seem blown, then your transformer is more than likely the culprit, and will need to be replaced. Soldering skills are required, and this is a pretty complicated repair, so I would suggest getting it to an authorized service center. A service technician can also determine if there are any capacitors or resistors that also blew, or might have been the initial cause of the damage, which is another reason why I do not recommend self-service. Utilize the REPAIR SERVICE option in FIXYA.com to locate a reputable service center in your area. If you cannot locate one, the company I work for offers Nationwide service, and we are experts with the 1200s - we also offer free return shipping. However, I am not sure if I could post the company information here. We are listed in the Repair Service search. You could also contact Panasonic, which is the parent company of Technics to obtain a list of authorize service centers in your area. Good luck! Hope this helps some.

There are two internal fuses that you can check, their positions and values are determined by which country the unit was sold in.
