I have a Rca RC651-A clock with an ipod docking
Do not take it apart. Instead contact RCA and explain what has happened, including having lost the receipt. They should be able to see it gets repaired or replaced. However if you have opened it, that will break the warranty that came with the device, regardless of the shops policy. And RCA will charge you for the repair.

Can't sign up for zune account
It all depends on the browser you're using.
Open your settings for the browser, and if possible, add the website root (the part up to .com) to the "Safe site list"
it could also be that the site is trying to popup a window and you should allow pop-ups for that site.
Thinking about it - I'm not sure if Zune is available anymore... even though I do have it, i'm not sure you can sign up for a new account now as it's listed as a legacy device. I would recommend if the steps above do not work contact Microsoft support or search the Microsoft Community for any additional suggestions.

My Onkyo tx-sr707 AV receiver
You may know by now Onkyo has severe HDMI board problems. If your unit comes on with no sound, forget about the heatsink solution. The second solution of wavesoldering the Ic's is chancy at best, and requires someone with proper soldering equipment for Surface mount flat pack ic's. I've seen a hear gun attempt blow the surrounding electrolytic capacitors out of their cans. Onkyo extended the warranties for many of their high failure boards. Check the following site to see if you qualify for the exchange/repair/replacement: http://www.avsforum.com/forum/90-receivers-amps-processors/1652514-onkyo-acknowledges-failed-units-extending-warrranties-until-2018-a.html.

Onkyo TX-DS494 stereo receiver won't turn on.
First, check which type of protect first.
3 seconds (DC protect) OR immediately shut down (Over Current protect)
How to confirm?
1.Unplug the amp.
2.Remove the metal cover.
3.You will see a long vertically installed pre-amp board mounted next to those large power transistors fixed by 12 screws on a large aluminium heat sink.
4.Remove this long vertically installed board mounted by 2 screws.
5.With 2 screws removed, just pulling this board out and hold it with one hand.
6.Plug the amp and switch it on.
7.If your amp stays ON forever, the problem is from this long board.
8.If switch off at once, the problem is from power amp board.
Try the above- mentioned steps. If DC protect, write an email to me via searching you tube SR600 capacitor replacement. Don't be afraid.
So many people wrote to me.
If over-current protect do the
(O)unplug the amp.
(1)download DS-TX494 service manual.
(2)open the amp metal cover.
(3)measure 7 large white resistors resistance loacated next to power transistors mounted on a large heat sink with black probe touching the middle pin and red probe to first/left or third/right pin.
(4)If this 3 Pins large white colour 0.22ohm x 2 resistor is open with infinity ohms ,
(5)replace it and jot down this channel for example left surround faulty. Usually only 1 channel went faulty.
(5a)When the white resistor didn't burn, "2 channels" were damaged due to bad soldering joint of the large white resistor, however.
(5b)When this happened, time taken of shut-down due to over-current is 3 seconds NOT immediately.
(6)the two large power transistors next to this white resistor 0.22 ohms x2 should also be replaced.
(7)plug the amp
(8)switch it on
(9)if ok, troubleshooting get done
(10)if not ok
(11)replace ALL the components of this power amp channel.
(12)pre-amp section no need to check.
remember if not OK, the replaced 0.22ohm x 2 resistor and 2 power transistors maybe shorted again. Check them first. If OK, replace ALL Components in this channel except 0.22 ohm x 2 and 2 transistors. 0.22 ohm x 2 means left and middle pin 0.22 ohm as well as right and middle pin also 0.22 ohm that are 2 pieces of resistors with 0.22 ohm in a large white 3 pins resistor.
Remember sometimes the
0.22 ohm white resistor is normal. If so, use a digital multimeter to measure the be bias transistor voltage via multimeter diode test function. You can compare the normal value,580mV to 650mV with faulty one,3.2mV. And the CE resistance is 1.8ohms only instead of 3 Mega ohms.

Need a universal code for a Sony (Dav dx255)
You have this backwards. An applicable code would be in your Insignia remote control, if it is compatible. Try using code search. If no luck, you may have to try a different universal remote control. All universal remote controls do not contain all possible codes.

My headphone slot won't work
so long as you are not plugging in a headset(mic/phones) into it. those have different connections on them which dont line up and short out. yours needs a 3 connector plug ie standard TRS 3.5mm stereo.
