Question about Technics SA-DA10 Receiver

1 Answer

Power Amp Module

Turned unit over to a guy to fix it sometime ago and he keeps trying. He thought it was the power amp module as well but could only find replacements at $80 each, so he tried removing one side, and replacing it with the center module, trying to sort which might be bad. So far no improvement. He is now tracing signal thru the thing,  Any idea where to get replacement power amp modules for less than $80 each? If I have to replace all three sending it to a landfill might make more sense. Any response will be appreciated.

    I've lost my right and left channel but not total sound loss. The switching relay for those channels, one of five doesn't hold. When I slightly flex the board or tap the relay, it will make contact and I will get a very faint sound. I believe I lost the power module for the front right and left. I ordered a new relay from electronic goldmine as agood measure. I have worked on ab amplifiers before and have replaced power transistors before. When locating the power amp module I am assuming that they are on the heat sink like power transitors on older amps. Just to be frank where are the power mods, what exactly to they look like and what is the part number and where can they be bought? thanks

    i have some kind of problem with this receiver ,is a desing problem,the power module for the channel A is on tha same heathsink with the sorround amp module so they go hot and the heat protection activated and turn off the sound
    if you see at the rear panel,a gan even is hot that don't turned on
    i put a 9vdc (cell phone)power adapter and conected to the fan and the small transformer hooked to the ac terminal of the reciver ,that one on the rear,so when the reciver is turned on the fan start working and now the reciver work ok.

There may be more reasonable prices around but you will need to post the type number of the module.
Unless it is a proprietary part number, it should have 2-3 letters, then several numbers following and perhaps another letter.

These units seem to have more problems than others in their class and they may have inadequate output protection.

I have pioneer cx -770os the sound just stopped It and my tuner are powered up So why.. does it all power mob the equalizer shows music is playing but no sound and how do I fix it

According to the service manual the main amp is on a "power amp module". If that goes I guess it takes out all sound, but leaves everything else working.
You can see the manual here, but it doesn't say much about the power amp module.

Yamaha RX V671 will not turn on anymore after a power outage

The protection mode has activated.
Reset the protection mode as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

Hi My name is Randolph, I have a technics SU-G50,how do I know if the main power module is blown? The system lights up but doesnt produce any sound and the relay in the power amp section is shot. Also...

The power amp IC for this is an SVI3206 which is listed as no longer available. You can check with some local service shops that may have some in stock. Realize that this IC is not cheap ($75 or more if available). If the relay does no click, there is a god chance that the IC is defective. I have seen some cases where there was a problem with the voltage regulator circuit that was preventing the amp section from working properly. Without seeing the actual unit and testing it, I can't say for sure.

It doesn't want to work anymore!! There appears to be no power to the Disc Player, Cassette Deck or the Sound Processor? The Amplifier screen displays F61 Hope you can be of assistance Thank you

With my crystal ball I can see its a Technics 4 part Hifi micro system you have although the image is just too fuzzy for me to tell which model.!

Joking apart...Your power amp module has a blown channel. These are specific Technics modules and some for the 3/4/5 channel units are quite expensive UK £40-80 just for the module + fitting costs

No DIY fix I'm afraid

I have a TX SR 803 av reciever that keeps losing it's audio. I have to keep reprogramming the audio outputs,sometime this works and sometimes it doesn't. Zone 2 is fine. problem began after a power outage

Try to reset your amp then go to the bottom of the set up menu and you should find lock set up,if this dose not work its repair time for your amp.

hope this helps.

HK avr125 5.1, no display, no functions.

Same problem. C901 on the vertically-mounted input board next to the power supply transformer was burned. Replaced with ceramic cap from RS with same specs. Still did not work. Talked to Jeb, great guy at HK tech support. He suggested that R901 would probably be blown and maybe 902 also. These are flame-proof resistors and do not show damage. Tested with multimeter and Jeb was spot on. Replaced 1w resistors with 5w (all RS had) at same resistance. Works great.

I had the same problem. As soon as the volume reached about 24db it would go into overload. I was able to fix it by soldering all the connections on the larger power module. The one connected the the heat sink. When I took it apart there where several solder points that had come loose.
