Technics SA-GX350 Nonfunctional - Click, then nothing.

I have a Technics SA-GX350 5-channel surround sound receiver. The service manual can be found here.

http://www.eserviceinfo.com/downloadsm/33514/Technics_SA-GX350.html
This is a great receiver and has been working for a long time. I bought it at a yard sale about 7 years ago and have never had any problems with it. Then all of a sudden, about a week ago, it stopped working. I press the power button and I hear a click coming from either the transformer or somewhere around it. Nothing else happens. The display doesn't light up, no sound comes out of the speakers; nothing. I took it apart and inspected it the best that I could. The only problem I found was two 330 ohm resistors that appeared to have blown. I replaced them, but this did not fix the problem. No fuses are blown, and none of the components (besides the afore-mentioned resistors) appear to be damaged. I don't know what's wrong with it, and I would love to get it working. This is a very good receiver (at least for my budget), and I hope I can find a solution. Thank you

    Apparently my knowledge of electronics is inadequate for this repair.
    I can't match the components in the schematic with those on the actual PCB. I don't really know how to read it.

    The Q751 that you told meto short to ground...I can't find it. it isn't in your schematic, and I can't find anything in the service manual besides that it's a transistor, and it's part number.

Initial response:

There could be a number of reasons for this. It woyld help if you could indicate what resistors you changed. The circuit designation should be marked on the PC board. Please post those here and I'll look further and provide some possible solutions.

Thanks,

Compatibilty


If what you say is true, you should be fine.
Where you get into trouble is having an amp of higher power than your speakers. That means you will likely blow your speakers.

My Technics sa GX350 tuner keeps going into overload. It's the only thing plugged in.


Hi mate, had the same problem with my amp.. Take the top off and there is a fan at the back, there are 2 piece's of copper flat wire that touch together and these do not touch anymore so when its turned up or the bass gets stronger it cuts off as the fan should kick in at this point. If you can get these to touch again (bend them) then the problem will be gone!! I have had to do this a few times now though so this is not a long term fix.. I may try soldering!

No surround Technics SA-AX530


There is likely separate gain controls for your surround channels on this receiver and they are probably set at -10dB. Enter the setup menu labled "level" and increase the amount for each channel equally.

Surround sound very quiet - technics amp receiver


darn, that was one of the best receivers ever built for the money! all the new receivers these days have 7.1. i would rather have more power in only 5 channels. puppy **** and electronics just don't mix do they? here is the link to get a new one if you like: http://www.google.com/products/catalog?q=SA-DX940&oe=utf-8&hl=en&cid=9395541207809312385&sa=title#ps-sellers

Technics surround sound system


Use whatever TV sound output conforms to your receiver's input. If an optical or coaxial digital sound output is available, that is the way to get 5.1 surround sound through the SA-DX1050. But you have to assign the correct input (COAX, OPT1 or OPT2) to the selector (TV, DVD, CD). See pp 12-13 of the operationg instructions for D-Input instructions. If you don't have the manual you can download it at Panasonic.com.

I hooked two Receivers up in series a Technics SA-DX930 and a different kind I'm not sure wut kind. They worked great for a while, but when they got turned up a little louder they both quit puting out...


you blew your power amp board, you cannot hook them in series due to impediance matching and improper input levels, cheaper to replace reciever than the board
