Question about Onkyo TX-DS555 Receiver
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.

Testimonial: "ok. i was expecting much worse news! thanks a lot for your help!"
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.

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.
