Yamaha RX-V879 receiver - display panel is not lighting
System works fine but the display does not light. I just moved and packed the unit carefully in the original box but on hooking it up in new location the display is not functioning. Is there a simple fix such as a fuse or LED that can be done? Is is there a place to get a wiring diagram? the manual doesn't seem to address this problem. thanks

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
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 summaryof 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.
ok yu problem has to be with the protection system before you burn it up it collapses to protect the whole system.....go direc to the thermal cut off devices on the main output and then to the power system......
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,
