technics amplifier su-d5000 service manual

Power down,disconnect the speakers and power back up. If it still say's overload, it needs to go to service. If not, check your wires, connections, and speakers one by one to hunt down the problem and correct. Hope this helps

use tape1 record out to the Line in jack on your computer. you should then be able to record to .wav, .mp3s etc. with an audio program like Nero.

Sll I can think of is that a belt or something else out of alighnment

Check for dry solder joints especially on the main power output transistor.A blown power transistor will stop the 'Current Drive' from engaging so if the problem you have is intermittent then it is most likely dry solder joints.Hope this helps.

You most likely need an alternator, usually in day it will run due to not using lights,etc,

The original remote control is no longer available from Panasonic. This site says they have the replacement remote you need. You can search for others by the remote part number or receiver model number to find other sources.

HAVE YOU TRIED DISCONNECTING FROM MAINS FOR AWHILE

That should be answerable but first read the instructions they contain some amazing information. I can not help you because I have no idea of what you want to know.

I had the same problem. The solution to me was presoldering transistor Q708. http://www.flickr.com/photos/37147023@N03/3511227679/?edited=1

check volume balance between right and left-then change inter connection between sound source and amplifier with new cabel(i prefer gold plated type connectors)(see radio shack).
after that if the problem excit your fault in output transistors or output stereo ic depend on circuit design.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers. Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up. You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it. If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good. If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech. Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.
