Question about Home Theater Systems

1 Answer

Switch Noise I have had this unit since 2004, no problems until now. For some reason now when I change functions or effects either directly or with the remote there is a loud accompanying bass buzz/bang (circa 1 sec). This occurs on all functions, DVD, TV and Tuner playback. I haven't changed the settings and have not introduced any new components into the set-up or the vicinity. I wondered whether this was a common problem associated with audio equipment of this kind/age and whether there is a known-solution OR if this is just due to the age of the components and I should look to replace the unit (although 4 years old seems a bit soon). Any suggestions gratefully received. Many thanks!

    The Unit is a Yamaha AV Receiver RX-V440RDS (6.1 Channel AV Home Theater Amp)

    thanks

    I will try moving it as suggested, however, I fear it is more likely to be a faulty IC or transistor as I haven't introduced any new power items locally. As I'm not knowledgeable in this area I will have to compare cost of repair versus purchasing a newer unit. Thanks

Try moving the unit away from power sources, for examples power adapters etc. The noise it is probably because of a faulty transistor or IC in the AMP section of the device.
To fix this you need to take unit apart and test components on the Amp area of the board, as this happens with all devices it is the final amp section having troubles.
Strange thing that device restart normally after this.

The selector button no longer works on unit or remote...AU...CD...Tuner ...etc. WHY???


If the selector button on the unit AND the corresponding button on remote has no effect, then the problem lies with the digital circuit responsible for changing inputs and not the Remote or the selector knob on unit.. I am assuming that the other functions do work.

That puppy needs to be repaired unless you can live with the input that it is stuck on. U might try unplugging the unit for a while and then replugging it. On some newer models this "reboots" the electronics and restores operation

Not reading DVD and CD's :-(


When you get no disk error, that is usually because of a problem with the optical laser lens that is dirty, faulty or opaque, and will start operating on certain disks better than others.

In that case you will hear disk spinning, whirring and clicking, but the TOC (table of content track at start of CD/DVD will not be read, therefore the error.

Whe this problem is starting you may be able to read only CD, DVD or Blue ray, or for example only DVD-R and not +R , or only to read and not to write and so on. After more prolonged usage , often the unit goes losing the rest of functions, and ends up not reading anything at all.

If instead there is no noise, and disk does not spin at all , then there is a faulty motor, or the motor micro-switch is bad. This situation is far less common than the lens problem.

Try first using a CD/DVD or Blue ray lens cleaner disk to clean the lens. If that does not work you will need to disassemble the drive , and clean lens directly with q tips and isopropyl alcohol, or to replace the CD/DVD lens, or the whole drive unit.

Multi Effects?


Here's a run down of the 2488 effects. It should explain how to use them.......

Effects processors can be inserted into the appropriate channels simply by holding the required effect mode button and pressing the required channel selection button. When the effects are configured as eight channel insert effects, the processor can provide compression, de-essing or exciter functions (selectable independently in each of the eight installations).

If you only need four such insert effects, then you can substitute a single multi-effect processor for the other four. This multi-effect is most likely going to find its way into the guitar DI input, and offers a chain of effects starting with a noise-gate followed by either distortion or compression.

If you are happy to abandon channel insert effects entirely, then you can set up the effects block as a single send/return processor which provides somewhat higher-quality effects. Algorithms include reverb, pitch-shifting, delays, and so on, and are accessed by dialling in an amount of Loop Send from any appropriate mixer channels. There is no dedicated effects return channel as such, but the level of the chosen effect can be adjusted in the relevant control screen.

Flashing standby message.


Are any of the buttons not making a click feel when you press them like maybe one is stuck?? You didnt say if the same thing happen with the radio as did with the cd. If it is then a switch is stuck or bad or a problem with the switch matrix for the Microprocesor . Only way to trouble shoot this is I would use a scope and check all of the matrix {ie scann lines as well as input lines for distortion or noise and make sure when the buttons are pussed that they change and switch accordinly. If they dont then the processors bad. Good luck

System unresponsive when modes are switched


Sounds like there may be a glitch in the microprocesor. Make sure when you unplug it that you leave it along for a few days and is there any type of clock or standby batterys in it take them out as well. If that dosent correct the problem your gonna need a service manual to trace the switch pulse to see if the units Switch matrix lines are low or lost because of a faulty micro or a bad componet like a small caps they install on the matrix to keep noise off them. Hard one to call with out seeing unit and analizing unit Good Luck
