It sounds like the LED for the display has burned out. The repair would require you to dis-assemble the unit to expose the front panel board. You will then need to melt the existing solder holding the defective diode and pull it out. Then you would install a new diode and solder it into the board. You will need to replace the existing diode with a new one rated for the same wattage. Also you should verify the the diode is getting the rated voltage to it using a fluke meter to make sure it is just the diode that is the problem. If you are not familiar with using a solder gun and circuit testing then you might want to call a technician. Let me know if you have other questions.

The receiver works great but there are no longer any lights on the front. We checked the manual and can not see where there is a fuse or light bulb to change help


If on the front display it is either missing a voltage source (connection or bad part) or the display itself is bad.

THE FRONT PANEL DISPLAY IS BLANK. HAVE I DONE


Perhaps, the manual mentions a Dimmer setting under the Display Set Menu but doesn't specify how dark it can get. Give it a try.

Display panel does not light; sound is ok


It may not need repair. if you have it hooked up to a TV, by video, s-video, or component. Press the menu button on the remote and you can see the main menu of the unit on the TV. Navigate the menu up/down/left/right/enter until you get to "display". You should be able to turn the display of the receiver on/off. If you don't have the manual. http://www.yamaha.com/yamahavgn/Documents/YEC/Stereo_Receivers/Manual/RX-797_e_U_p.pdf That's the PDF from Yamaha. I haven't used this particular unit, but that's the way it's done on all the other series. ie. RX-V or RX-Z. Hope this helps

The display light doesn't come on to indicate what the unit is doing (frequency, mode, etc.)


I assume that it plays, you just can't see the display. It may just need a new display bulb, that back lights the display.

Yamaha RX-V470 LEDs/Lights all out


Sometimes,you might press a "film mode" or "Dim"or "dimmer which will turn OFF the front panel display.Check that first from your manual.
It happened a lot!
If that is not the case,then you need A/V repair guy to order the part to fix it for you.

Front display panel


Check for bad connections on the display pins themselves. Specifically, the ones on the ends are the power/ground pins.
Let us know if that resolves the problem. If not, we'll look further into the circuitry.

Display is permanently "off" on the Yamaha RX-V620


Sounds like the LED that lights up the display has burnt out. An easy fix, if you're not afraid to take the front panel apart and resolder a new one.

RX-V1500- front panel lights not working


The display on an amp has two components.
A small Lamp (light bulb)
A LCD display with a color filter.
Normally when the display goes out the problem is with the lamp
The lamp on my RXV 870 died after about 9 years of use.
I called Yamaha and was able to by a replacement.
The lamp is an odd voltage 14.5 if I recall.

Looking at the receipt i should have bought 3 for the cost of shipping. It cost about 10.00 cnd,
