Question about Onkyo TX-DS555 Receiver

1 Answer

No Power The standby light is on, but receiver doesn't power up -- either by switch on front or by remote. There is no display & no operational mode is functioning. A blown fuse has been suggested, but I see no access panel for a fuse. I've checked the surge protector the receiver is plugged into & see no problem there.

The standby light is on, indicating CPU is now working.

but receiver doesn't power up -- either by switch on front or by remote. There is no display & no operational mode is functioning. This means the power on relay RL901 isn't ON, perhaps. Follow these steps:
(1)download TX DS555 service manual
(2)Unplug the amp
(3)open the amp cover(4)check the AC inlet board, PS6303
(5)see P.31 B(vert.)D(horizon.)(6)Check R922, R923 ,Q921 ,C922, RL901 and a T-fuse,thermal fuse, located at the primary side of the large transformer, ETC-6304.

The most likely problem is shorted output transistors. This is a straightfoward repair for any shop that works on audio gear. Expect a parts cost in the $40-$50 range.

SOURCE: Only the front speakers work none of the surround speakers

If you are still covered by the warrenty, then you may be able to get it fixed at no cost.

Otherwise get a qualified technician (I say this to cover my but rather than suggesting that you open it up yourself) to open it up and check the fuses inside.

SOURCE: Hello, My receiver wont come out of

If you push the power button and you hear it "click" that means it's getting power. Now, that being said... Couple things to check: first: disconnect all speaker wires at the receiver and attempt to power up, if it does, that's a good sign that your receiver is ok and your problem lies in the speakers or in the speaker wire. If you still can't get it to power up, pop the top of the unit. Most receiver's have 6 or 7 #1 phillips head screws on the sides and rear of the receiver. Pull these off. Look directly at the area where the power cord plugs into the unit (make sure the unit is unpluggged) There is usually a fuse right nearby. If it's a white fuse or gray fuse you may need to do a quick continuity check with a meter to test. If your familliar with meter's, just switch it to continuity/tone. If the fuse is good, you will hear a tone from the meter. If not, there's your problem. If your not sure how to test with a meter, either take it to Radio Shack or similar store, ACE hardware etc. they can test it for you and will generally have replacements in stock. If the fuse is good, your speakers are disconnected and you still have no turn on, your receiver needs to be serviced. If that's the case, whether you service or replace the receiver, get a good "Theater" line conditioning surge!!! like Panamax, Monster, APC, or Furman. A good unit will start around 250. Small price to pay for saving expensive electronics! Hope this helps. If you need further help, just post a comment and I will be glad to help.

Mum pressed some buttons on amp now the amp wont respond to the original remote or the universal remote. buttons wont work, batteries good and lights up. is there a button that blocks ir signal?


Looking at the user guide it appears that the amp has a standby mode.

See not below on turning standby on. Question can you see the standby light flashing.

I would also suggest using function on the amp to remove any possible issues with the remote.

One would expect the system to return to normal operation by pressing the power button again. If not what do you see on the display.

Note:
Press 1 to turn on the receiver.You can also turn on the receiver using 1 on the remote control. When you turn off the receiver, press 1 again. "STANDBY" flashes on the display panel. Do not disconnect the AC power cord (mains lead) while "STANDBY" is flashing. This may cause a malfunction.

May I know if the standby led light at the front panel is blinking, if so please count how many times it will flash to determine the error code? If not follow the steps below.

In standby mode press the button of the remote control in sequence, " Display ", " Channel 5 ", " Vol (-) ", " Power ". Self diagnosis screen will displays. Le me know the result.

I have a hitachi 50 "plasma that was given to me


First do you see a light indicating that the TV has power? There are two power buttons on the TV (the main power and the regular power button). The red standby light will light up when the main power switch is on. This indicator is just to the left of the remote I/R sensor. You can find the main switch on the bottom front of the tv (it is under the tv forward of the stand). Turn on the Main power if it is not on. Then try the power button on the control panel of the TV again.

Does the standby light change color or blink? (Red is standby, orange is power savings (no signal), blue is on.) If the main switch is on and the standby light doesn't come on, the TV has a problem at the power supply. Try unplugging the unit for a bit (at least 30 seconds) and then plugging it back in. This will reset the internal circuitry. If you see a blinking light, then the TV is reporting a self-test failure. I do not know the codes for this model Hitachi Plasma TV.

The manual for the Hitachi P50H401 TV is available from Retrevo: http://www.retrevo.com/support/Hitachi-P50H401-TVs-manual/id/1233ci869/t/2/ . You will need to enter a code to access the pdf.

I'm assuming you don't have one of the special versions that were intended for large audiences that were only controlled by remote (no control keys on the front of the TV). Remotes.com has the original remote or a substitute remote if you need it. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13104063628240&smodel=P50H401&brand_pn=HITACHI_P50H401 .

I hope this helps.

How to reset the recever?


Place the receiver in Standby mode (press the front-panel Standby/On Switch so that the Power Indicator turns orange).
Then press and hold the front-panel OK Button on the Receiver ( not remote ) for at least five seconds until the RESET message appears in the display. Then press OK. The system will go to factory default. All your settings will be lost like FM stations / Sound settings etc: .

Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps2_bing.gif metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers2_bing.gif are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

Lexicon RV-8 wakupe failure


Did you try this....

In the event of a power outage, the RV-8 will display a BROWN
OUT!! PRESS STANDBY message. To turn the unit on, use the
STANDBY button. For more information, see “POWER
MANAGEMENT” on page 3-3....

POWER MANAGEMENT ON, OFF

"Setup" >> "Power Management"

Opens the POWER MANAGEMENT menu, which is used to automatically
put the RV-8 into standby mode during brownouts.
When set to ON, the RV-8 detects low voltage levels or a momentary
loss of power and puts the device in standby mode. In the event of a
power brown out, the RV-8 will display a BROWN OUT!! PRESS
STANDBY message. To turn the unit back on, use the front panel
STANDYBY button.

When set to OFF, the RV-8 will attempt to function during a
momentary power loss, however software settings may become
corrupt and need to be reset.
When the RV-8 is in standby mode, pressing the button turns the
unit on and activates all zones that were active in the previous
operating session.

The RV-8 does not power on.
1. Make sure the rear-panel power switch is set to the | (“on”)
position.
2. Attempt to power on the RV-8 with the front-panel Standby
button and remote control On button.
3. Examine the power cord to ensure a good connection between
the rear-panel AC input connector and the wall outlet.
4. Check the electrical circuit and breaker.

How do I turn On/Off my RX 596 reciever with my Yamaha remote ?


Press the Standby/On button on the remote or on the receiver (right below the Yamaha logo) to stop the audio output and display. The RX-596 goes into a low power standby mode when not in use; this allows it to respond to the remote when you press the buttons. If you want the receiver's power use to go to zero, you need to unplug it from the outlet. (You could also use a switched surge protector and push the switch to off.)

See page 9 (page 11 in the PDF) in the manual for the details on the On/Standby switch. The manual is available here: http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000057561.pdf . The page is also available here: https://www.manualslib.com/manual/197512/Yamaha-Rx-596.html?page=11#manual .

I hope this helps.
