The LED screen on my Yahama AV receiver, is blank. The unit still plays, but without being able to see what I am doing, I am unable to verify that all settings and abilities are working properly. The model number is RX-V657. Any suggestions on how to fix the problem without having to take it to a technician?

Try this:

FIX ZONE @ SOUND - STUCK ON "ZONE 2 - FIX" 1. Press "Amp" button (right side of remote - 1/3 way down) 2. Press "Menu" button (center of remote - 1/2 way down) 3.

I suggest you run self diag.  press [FM/AM] key + [Input mode] key and press the [power/standby] switch.

ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink

you'll likely have to measure the resistances of the output FETs to find a short,

SOURCE: 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.
