technics amplifier su-d5000 service manual

F61 - error code. This will trigger if the unit has gone into overload to avoid further damaged to other parts. The common causes of this error code. 1. Output IC - this is the most common caused of the error code. Once shorts happened to this IC, it will trigger the error code. Exposure to high volume and/or running in the long time will caused this IC to shorts and produce an overload.
2. Shorted Speaker - if one of your speakers shorts, error code will appear also. This may isolate by disconnecting the speaker to the set and play the unit *****. If the symptom still there the fault came from the unit itself.
3. Shorted Inputs - inputs connector is also prone to shorts due to frequent bending and pulling. To isolate this from fault, disconnect all the inputs connected to the unit like the aux input, antenna, mic, etc.
4. Faulty power supply - once gone to out-of-regulation condition, the error code will appear to protect the most expensive parts from further damaged.Bad solder joints in this section is also to consider.
5. Faulty Fan and its circuitry - F61 will appear only after a minute of operation not upon powering on the unit. Check the fan if working or not...
Also, check whether your unit is still within the warranty period, because the manufacturer will fix it for free.

You broke the ribbon connector that bounds your changer and tape deck to the sound processor (the black long ribbon that is permanently mounted to the tape deck) - the cheapest option is to get a new tape deck (around 20-£30 on ebay) or hount for replacement ribbon

The answer is simple if you want to listen to mp3 on your system and you purchased dv290 dvd changer you also need dv290 sound processor as they were coded - for example you have dv250 system with dv250 chager and sound processor you are only going to be able to see dvds and cds if you swap your changer to dv290 (plays mp3, audio ,wma and dvds) you also need to purchase dv290 sound processor as well - no need to change your amplifier or tape deck (the ribbon on the tape deck will be compatibile)
the lower end units were incompatibile with higher spec changers same when it comes to EH series if you have eh780 sound processor you are only going to be able to plug 780 changer or lower 760 770 etc... but 790 will not work with it unless you get 790 sound proc

The drive ic is shorted or there is a small transistor that is bad not having the unit on a bench is is hard to track down the part. But it is a easy fix if you find the service manual and can do soldering the manual will tell you where to find the part that is making to run away! The main thing is to find the parts is you find the # on the parts I can or you can look up those parts. Good luck.

take the cover off, airdust it , check wiring harness on main board and back board. resecure. while leaving the cover off get a table fan and point air at it while its on. if it behaves you can now build yourself a internal fan out of an old computer fans ..

Turn the volume down to less than half.
Try each of the input select switches, and make sure the monitor switch is in the proper position,
If you have not used this stereo before, make sure the jumpers are connected on the back of the unit from PRE OUT to MAIN IN.
(If it was working OK and now it is not, the connectors on the back are fine..)

On some systems F61 is to do with the fan not working properly, sometimes blocked with dust. On others it's a power amplifier failure. Yours does sound like a power amp problem, but both should be checked.
