I presume you might have set the dimmer for the Front LED Display panel too low and hence you can't see any light.

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.

Denon AVR-3801 lights up,makes rapid clicking noises when amp tries to turn on. Clicking stops but unit doesn't play & sometimes the unit turns off. Occurred after lightning storm. What to do to fix?


Probably damaged by power surge. If you do not have experience diagnosing and repairing electronic circuits as well as having access to schematic diagrams then this is not a repair for you. Failure to replace all damaged components may result in damaging new parts.

FM Tuner not receiving - Yamaha R7 receiver


Take the cover off and look at the cable that connects the tuner to the main board. Make sure it is connected straight and tight. Make sure all screws in the back are tight, just in case it is a grounding issue. Iff all checks out and you still have issues, replace your tuner.

The failure of the front display indicates that there is a electronic fault.
So you need to check the power supply to the display panel, check the +5 to the processor and siplay drivers including the filament voltage to the display and the negative grid to the display. If not trace back to the power supply unit.
If these are present with no display check the linking cord to the display. Check the parameters of the processor which can confirm if the controller is working. if not you will need help for replacement of the processor and also since this is high densitty boad where service requires jigs and equipments.

You can select the display mode for the front display
of the SR7001.To select this mode, press the DISPLAY on the remote control or the front panel.When this button is pressed, the display mode is switched in the following sequence.Input Mode ? Surround Mode ? Auto display OFF ? Display OFF ? Normal Mode ? Input Mode Normal Mode: Displays the selected input function. If the function has been renamed using the Function Rename feature (see page 26), the renamed name appears on the display. Input Mode: Displays the input mode set via the Function Input Setup feature (see page 25). Surround Mode: Displays the status of the selected surround mode. Auto Display Off mode: The display is off. But, if you make a change to the unit such as the input or surround mode, the display will show that change, then go back to off after about 3 seconds. When changing the volume, it is not displayed. Display Off mode: The display is off completely. Note: • Only the DISP indicator will be illuminated on thefront display in display off condition

When you power on the stereo you see the display light on, then you here a click and it switch off.


We need a complete make/model etc to help you, however this is indicative of the unit not passing a power on self test. This could be anything from a shorted speaker lead to a blown transistor or hybrid amplifier IC.
Depending on the unit, it may or may not be cheaper to replace the unit.
If you are tech savvy, and we know exactly what make and model of amp we are working with, I can tell you where to look for damaged components etc.
If the unit is worth a great deal, or is in your opinion irreplaceable, you may need to send it in to someone like me for service.

Hello,

Your unit being stuck in protection mode is an indication that its having a power problem. Remove its plug from the wall and fix it back into the wall, then turn it on again. If its still stuck in protection mode, then the power supply board in the unit is the cause of the problem. The receiver is trying to avoid further damage, that's why it is on protection mode. Its protecting the receiver. This was how the manufacturer programmed it.

The power supply board might be defective and maybe that's why the unit is on protection mode. Its receiving power but it cannot transfer the current to the necessary part of the unit because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the unit might function.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

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

Sony STR de845, 5.1 Surround does not work. 3.2 is indicated o


3.2 IS the "5.1" mode for this receiver. 3.2 is indicating that you have 3 front channels and 2 rear channels. The ".1" is applied to all the speakers (LFE). If you read the manual on page 37, you'll see that "3.2" is displayed with either "Dolby Digital 3.2" or "DTS 3.2". The little icons of the speakers in the display window will show you which channels are active. The bottom line is as long as you see the blue light, it's decoding multi-channel discreet surround sound (at least 5.1).
