Question about Audio Players & Recorders
I have just purchased a used Technics system. I have the tuner, amp, and equalizer. The man I purchased it from also gave me a JVC tape deck but I do not have it hooked up with the Technic components. It worked fine when I purchased the units and when I brought it home and hooked it up, it powered on without any trouble. Today, i turned on the equipment and the amp comes on and then shows "overload". What is happening to cause this and how do I fix it?
i have the same unit and a similar problem, after a fall of the tuner on the floor while i was cleaning my room, first times the st-x302l was powering fine but after some minuts it quit alone.. now (i dont know why) it remains on but if there is an interruption of electricity it dont turn on anymore, it turn on only by removing the metal chassis and moving random the electronics.. i think it has some electronic contact or circuit break.. i brought it to a specialist in electronics and he told me the reparation would be too expensive so i prefer to try fix it by myself.

First connect all sources like tuner, cassette player, Cd player into the proper RCA inputs of the control amp, then connect the output of the control amp into the input of the equalizer. Then connect the output of the equalizer into the input of the amplifier. This is how to get the best performance and proper outputs to all the right equipment. The speaker outputs of the amplifier would then go to the speakers.
Let me know if you need more help from me by addressing your post to me, or if you wish to communicate with another expert you can address your post to them I.E. @tech48 or @whoever
Thanks and good luck,

yes it can be fixed , the input may have shorted and is now protecting the other circuits. it will need to be looked at and tested to make the repair. so calling and probably having to take it to, an electronic repair shop will need to be done.

The question is, do you hear any sound? Is just the display off or is the entire unit shutdown? Can you tell?
These displays are known to develope poor solder connections at the power input and ground pins. If you can solder, open up the unit (unplugged of course) and examine the pins for the display. This will be on the PC board attached to the front panel. The pins at either end of a long line of pins will be the power and ground pins. Reasolder those pins, taking care not to short the pins together and try the unit once done. If that does not resolve the problem (assuming it is just a display problem), update this with as many details as you can about the behavior of the unit and we'll look further.
