Is the buzzing coming over the speakers or just from the receiver itself?
If over the speakers:
Try swapping ports on the receiver from the DVD. Go from DVD into an auxiliary video or VCR 2 if available.
Try swapping out the cables with known good ones.
But do this in steps to be able to nail down the problem and not just leave a mystery.
If the sound is solely coming from the receiver it could be a dusty fan. Blow it out with compressed air ,With the Power Off.
Or, my favorite, might just have to crank it up so you can't hear the buzzing.
good luck

Where to buy transistor for hk3480 part num 328 kca3114


Hello,

Are you sure that is the part number? The HK-3480 uses a KTC3114A and is quite easy to find. Q317 and Q318 in your receiver.

Make sure you see the numbers correctly.

I have a Sa-ex900 amp hooked up to Television ,vcr and dvd player. When I turn the amp on and want to play the tuner , the television bleeds through. In fact TV plays through all buttons except VCR1


Hi,
it seems to be ,you have a possible wrong connection..I
may I recommend you to check the connections in accordance with my model connection procedures given below and correct if something is misconnected..

I believe Your Television ,vcr and dvd player all connected to each other thru Technics Receiver itself (not directly connected to each other ) and whenever you want to listen/watch any of it ,you make a selection thru Receiver..
** in order to do this both DVD and VCR 's "2xRCA audio" and "1x RCA Video" cables for "IN" and "OUT" should go to Receiver separately ..("IN" goes to "OUT" of other ..pls remember,Always reverse connected )
** Additionally your RECEIVER's prefably only "1xRCA Video Output " should go to TV to watch the video of both DVD and VCR (audio will come thru Receiver.)

Ok, now Since you successfully connected your Receiver to play video on TV (one way only ) ,here is the second reverse action to listen your TV on Receiver
** you need to connect "Audio Output " as can either be : RCA jacks or "Optic cable output" or "SCART "connector " of your TV .( every TV has different type of Audio out jacks )
** to "TV input "or "AUX input" or "Optic Cable input"
of your Receiver (whichever you want ,based on the necessary cables on your hand )
** than just switch to respective mode on
Receiver corresponding the connector you have used on the back of Receiver ..
There you go..Tv sound are on the
Receiver .

Hope this helps!..if more help requires pls let me know.
Take care and please

I bought the hk3480 about 6yrs. ago. It was put in a rack and tested and then sat for the next 4yrs. unpluged. I got home and pluged it in hooked up some speakers and iw lit up all functions work etc....


Never use maximum volume for troubleshooting. The errant switch or control that you eventually find and flip will suddenly release the amp's full power and you'll destroy your speakers. If a signal isn't audible at 1/2 volume it's probably not there.


There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

I have no TV box but do have cable, how do I hook up TV,VCR,DVD, and YAMAHA HTR 6030


For watching TV, your TV should have a monitor out. This will go to your CBL/Sat input on the receiver. If you have a newer TV, it will have an optical output,if you use that, you will have Dolby Digital surround when available, and digital stereo at all other times. For the VCR and DVD, if they are separate units, Run audio video from the VCR to the receiver to VCR 1, for the DVD, use Component video and optical or digital coaxial to the receiver. Then from the receiver run component video to the TV. If you need further help, post a comment and I will help you further. Hope this helps

Humming sound when watching tv,but not when watching dvd's


It wounds like you are getting interference from you tv to the receiver. You can try a few different things here.

1. Connect the tv output into another input on you receiver to see if it isnt the channel on the receiver.

2. Try a different set of cables between the tv and receiver. Faulty cables can give you problems.

3. Connect the cable from you tv to a different device. (another dvd vcr blue ray etc.) This will tell you if its the receivers or the tv.

I dont know how to hook up my rca receiver to my dvd player and my tv and vcr so i can have it all running i dont know what wires go where


first check your receiver if it has inputs for all those gadgets you wanted connected. in your input function selector see if there are options for your dvd, tv, vcr. if it does have all those inputs then just connect all the audio output left/right rca jacks of your gadgets to each input function of your receiver. your VCR though is different, you have to connect the receiver input to vcr output. the vcr record goes to the vcr input connections. your TV, if it has got any audio out then connect to the audio in function of your receiver.

Powers off when watching dvds


Hard to say if this indicates a more serious problem that should be looked into. If under warranty take the receiver back to the shop and let them worry about it. If warranty no longer valid, you should let a professional Yamaha service person look into it. But first lets see if we can't work around this problem. Is the DVD connected to its own power supply, or connected to the AC outlets in the back of the receiver? in case DVD player's power cord is connected to the back of the receiver, I suggest you connect it independently to another electricity socket, and see if this has any effect on the problem. Another thing to try is to connect the DVD audio cables to the receiver, and the video cables directly into the TV. Even if this helps you solve the problem, you're better off having someone look into it. especially if under warranty, don?t think twice. good luck
