No display on a Yamaha Natural Sound Stereo Receiver RX V1070

There was no display on a Yamaha Natural Sound Stereo Receiver RX-V1070. A burnt out backlight was suspected. This video shows how to open up the receiver, how to find the burnt out bulb, and how to determine a replacement by measuring the voltage and using a resistor substitution box to get the right brightness from another bulb of indeterminate rated voltage. Using the resistor substitution box, a suitable dropping resistor was determined.
