Question about Onkyo HTR500 Receiver

Open Question

Onkyo HT-R420 will not power on. Sometimes if I unplug and plug back in, the standby light will blink for a few seconds and then go off. One time I got the system to power on and it just clicked on and off about ten times before going dark.

If you look at the manual, there are steps detailed to reset the receiver. This usually happens if the receiver becomes very hot. Try resetting and you should be okay.
The other problem is short circuit on the speaker wires. Check the speaker wires again.

SOURCE: onkyo ht-r500 no speakers attached goes directly

I have a HT-R520 - First thing stated in the manual is 'Do Not Apply Power to the System Until All the Speakers Are Connected to the Receiver.' This practice avoids any hot connects to the speakers. As with any high-outpiut system connecting spreaker wires to the system while in operation can spike the speakers as well as the amplifier curcuits. Hook up your speakers first and give it a try. Good Luck!

The unit most likely blew up a capacitor. If you look in through the slots on the top of the unit you should see 2 big black caps (C6901 and C6902) with shiny silver-ish tops. I should also point out that you probably flew up a 125v 8A (F901) glass fuse on the board that the AC cord plugs into. The glass fuse can be found at Radio Shack, but the caps are a bit more troublesome to find. They are 10,000uF 69v and thats just not a standard part, so you may need to up the voltage requirement and buy a 75v cap. Total to fix the amp yourself: Should be about $35 with shipping.

What do 7 blinks indicate?


The Vieras have standby codes that are not published because few Plasma TVs are serviceable by owners. Power surges will cause the blinking sometimes and the only remedy to the owner is to unplug the TV for a few minutes to let the power supply reset and plug it back in to see if you still get the shutdown mode blinks. If you do, the only remedy is to contact Panasonic at 1-877-95VIERA (USA) or 1-866-330-0014(Canada)

I have a sony trinitron wega 32HS20 when i power it up the standby/timer light blinks 11 times then the picture appears sometimes it will stay on all day and sometimes just a few minutes then it powers off...


Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

Power problem


Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

Onkyo HT-SR800 won't turn on


If you call Onkyo directly, 201-785-2600, there is a procedure to "reset" the system, something like holding the power button on and holding down another button for a few seconds. Can't remember which, so I can't be sure, but try giving them a call.
