Well colleagues I have this equipment repaired and I connect it in normal demo but when I turn it on it turns on for a moment and it turns off, leaving the LED of the power key flashing between green and red I would like you to give me your suggestions to know what to check or what can be the cause of this greetings and thanks for your attention ---

It has a problem in the power amplifier stage, the STK must be defective. Remove the integrated and turn it on again, if the equipment hangs you must change the integrated, also check components associated with the integrated STK. Regards.

Another problem with this device is that the carousel of the discs is out of time due to a broken gear. Is it possible that it will come into protection for this? Of course the integrated thing is as much as possible greetings and thanks for answering

Hello, Disconnect the flexes that go to the CD part and turn it on, if everything works fine, the problem is there.

Excuse me friend, I have the same problem with the partner, only that I already replaced the STK 412-150 and it worked, but a week later it was put back in protection by turning off after 3 or 4 seconds of turning it on, sorry that components associated with the STK could check? I hope you can help me. first of all, Thanks!

The problem is in the amplifier stage, measure if you have voltage on pin 2 of IC550, A voltage greater than 0.6v on pin 2 will activate the protection.
