If you dont mind a lettle customization, just go to radioshack and set your favorite color l.e.d. and wire it in, if you can find a specs diagram for your reciever, you might look up voltage and wattage of the bulb so you can get appropriate resistors for the led, and install that. itll last forever, cost virtually nothing, and its easy to do.

Do I need to connect my older Fisher Turntable to a pre-amp before connecting to my Yamaha RX-V850?


No, you don't need a preamp if your turntable has a moving-magnet (MM) cartridge, it should work as-is! Happy vinyling =]

There's a common problem with the Rx-V661 where a capacitor blows and then the display on the unit no longer works. It will start to display when you first turn it on, but fade out right away. This is because of a blown capacitor and a known issue for the Rx-V661.

Yamaha RX-770 Receiver display quit


there is a bulb inside the backlight on the lcd display.it is 12 volt and alot of manufacturers run it from the +- 15 volt preamp power supply,on the plus rail.when the bulb burns out it can activate the dc speaker protect,or some other 12 or 15 volt circuit..if it is a flourescent display that is a different problem.those run on 5 12 18 and -32 volts.there is also a 6 volt ac filament voltage.you need the schematic.

Yamaha front panel display dim


Yamaha RX-V661 LCD / Front panel.





Symptom: when you first turn it
on, you can see a VERY little light but after 5 sec, you cannot see it anymore
or for most of us, we started using a flash light. Here is the summary of the solution and I know that it works
because I fixed it today 3/16/2011, 30 minutes ago.
As many pointed out that there is a
"light" 12v - 14v in the back but there is NONE. How do I know? I listened and searched and
there are NONE. The whole LCD in the front is air seal like a light bulb so it
is a light bulb already. Also, you might
see a little burn/gray smoke on the left hand side, don't worry about it
because if the light comes on, it stills work but not enough power. If the LCD
is broken, please don't try by the part and replace it because by the time you
read this, the parts and labor cost as much as buying a new one (on eBay and
not Best Buy).






Problem: in the middle of the unit near the back near the "surround
sound back", there are 3 capacitor rated at (2 units) 35v 220uf 85'C and
(1 unit) 50v 220uf 85'C. What Yamaha did wrong, base on my guess is that they
put the 85'C too close to the heat sink.
The heat causes the capacitor to slowly blown that is why you still get
your power to the LCD but not enough.






Solution: remove the top, unscrew EVERYTHING in the back and there are about 20 ~ good luck. For
those that don't have good memory, please take a picture. There are many plugs inside
that you need to unplug before you can remove 1st layer (audio/ video input)
2nd player (HDMI and Optical input), the last layer you will see 3 capacitors that
are kind of "blown" up (google "bad capacitors" pictures or
video). Remove them then replace them, which you can Google this on tube and
they should teach you how. It was very easy for me but then again, please don't
try to do it if you cannot even change your car oil or build a computer because
I believe that is the difficulty level.






solder iron: $9-$20 get it on eBay or radio
shack

(2 units) 35v 220uf 105'C and (1
unit) 50v 220uf 105'C or what I got was (3 units) 50v 220uf 105'C



I keep the 220uf the same to be
safe but increase the voltage and heat to increase the life of the capacitors.



Good luck everyone,

My yahama rx-463 does not reconize the sub-woofer. any help?


Typically a/v recievers have on/off settings for each sound mode. This is likely the cause.

I need a display bulb for a yahama rx- v850 av reciever


The display bulb is a 14 volt bead style lamp about 0.150 inches wide with wire leads. You'll need to cut the old bulb off the two -pin cable assby and wire the new lamp into the existing wires.

partsexpress.com
mcmelectronics.com
or
studiossoundelectronics.com should have lamps for that

Yahama RX-V590


Sorry to have to tell you but that means there is a short in the output circuit or the power supply. I would bet that one or more of the output componets are bad. If you know solid state circuit troubleshooting, It still may be worth repairing. if you do not then most likly it is time to get a new unit.
