LED display is off

My receiver is working fine except that the display is completely off. I have had the receiver for about four years. I don't know if it will be a costly repair or not. Any advice?

    I have the same exact problem--happened yesterday. I don't think the "buy a new display" is the right solution for everyone. It might only be available to repair centers, and only the technicians may be able to install it.

    all of a sudden the buttons aren't working the right items. ie, when DVD is pushed, TV sound comes through. TV sound also comes through if the TAPE button is pushed. it seems all the buttons are working random outputs?? unfortunately, my dad doesn't have the manual. although, i'm gonna try and find a pdf after i post here.

    thank you.

    Mine just went off a couple days ago. Everything else seems to work fine, but no LED display. While I'm trying to figure out what to do, I worry that I'll accidentally hit the wrong remote button and put me in a mode that I cannot get out of with the still working onscreen menu.

The service manual might help, if you're a tech, but the circuit board assby is : onkyo part # 1A928503-1A also called NADIS7403

I would have a technician check the power supply lines for the circuit card and the solder joints for the flex cables to the circuit card.

I would also suggest unitedradio.com

I just bought an led light set for my new diamondback bike. Which is fine except I don't know how to attach it to the bike the pieces that came with it only attach together. Am I missing something?

If you feel pieces are missing, return the unit and get a new one. Aside from that, you would have to improvise a fastener to attach to the frame or handlebars. 7_16_2013_10_17_55_pm.jpg

When pluged in the On/Standby LED will light. When pressing power the On/Standby LED with flash then go solid but nothing apears on the display. I can select what speakrs to use (A or B). All the LED's...

Most likely the unit does not receive power from main transformer. Possible several reasons:
- bad power transformer
- bad main internal fuse 7-8amp. Bad fuse most likely because of one of the channel is blown and shorts the power, so before installing new fuse good idea to check all channels by meter or at least visually for burned parts
- bad power relay
- bad connection, cracked soldering joints

Harman/kardon avr 247 no audio or LED display on the reciever

I've had the exact problem. HK in the states is no help, you need to deal with a company in Montreal (Jan Industries). Regular techs are unable to fix it without schematics that only authorized dealers have and the manufacturer. This problem happened to me just after 2 years and outside warranty. I've bought a Yamaha today.

Garage Master 1/3 HP 1997 Door Working, not responding to Remote

I have the exact same situation, except my model (139.53607) is older than yours and does not even have an LED. Remotes only works after after shop light goes off (5 minutes or so), but wall button works fine. Did call Sears Service and the tech told me the logic board is probably shot. Don't want to waste money on service call so I'll probably have to buy a completely new unit in the Spring and go through the winter without the use of a remote.

RCA RTD315W Receiver/DVD LED display

If you are referring to the information display, it doesn't activate until you take the system out of standby (the bright blue LED at the corner is shining). When you hit the OFF button (on the system or the remote) and the blue LED shuts off, your info display comes on and says WELCOME.


Onkyo TX-SR502 AV receiver

this could be the pre amp transistor or the power amp that needs replacing
the pre amp transistor is cheap but the power amp is not
if you did not crank it , then it is probably just the transistor that needs replacing


Code for Sony BDP-S300 Blu-ray player on Onkyo remote

Player can be made to work without remote. But it is a pain.
You need to press pause then play in the right combination.and you can get both DVDs and Blu Ray disks to work. I bought a store floor model that did not have a remote. I went through the same problem when I would lose the remote for the HD-DVD player. My four year old daughter knows this trick pause pause play for DVDs and pause play pause play for blu
