If dust has built up in any of the cooling fans the system will detect that the fan is not turning and will not power up...The fans have an internal switch that tells the system not to boot ...blow out your fans and try again..the same thing happened to my plasma wouldn't boot..blew out fans and it was fine after that

Blu-ray unit won't power up. Any suggestions?


it will not hert you to unplug the unit and open it up, inspect the unit for any type of burning, or the smell of burned parts, if it does have a fuse it will be located near the power supple where the cord goes into the unit. remove all screws, some screws maybe hidden behind stickers that say quality control stickers.

you mite try unplugging the unit for a few hours, try a different outlet in the power strip, resetting the power strip default button. i do not think the blu-ray has reset.

This unit has two locks for demonstration purposes so discs can't be stolen.
Eject lock:
With the unit powered on, press and hold stop button and power button on main unit for at least three seconds until it shows unlocked.
Function lock:
With the unit powered on, press and hold play button and power button on main unit for at least three seconds until it shows unlocked.

Hope this helps.

When you turn it on The blue light flashes and it returns to the red light and will not turn on


This is a power problem from the unit. The unit receives power into it but does not supply the power sufficiently enough to get the unit to function well. This is why the blue light flashes when the initial burst of power is sent into the unit but due to lack of follow up power the unit fails to remain on.
Best get an expert to identify if the power supply distributor in the unit is bad or the ic which is responsible for the distribution is the cause.
Hope this solution has been helpful?

Yamaha rxv-992 receiver wont power up


Disconnect all your speakers from the receiver. Turn the power on, and see if it stays on. If the unit shuts off with all the speakers disconnected, then you most likely have a faulty unit, and it will need to be repaired or replaced.

If the unit stays on with all the speakers disconnected, then you most likely have a bad speaker or a bad connection with the speaker wire.

Starting with one speaker, hook it up, and turn the unit on, and again see if the unit stays on, or if it shuts off. Do this until the unit shuts off when you connect a speaker.

Then disconnect all the other speakers, and leave the suspect speaker attached. Again, try to power up the unit. If it fails with that speaker attached, but works when it is not attached, then that speaker is your problem.

Hi,

Take every single cable out of the unit, now power on the unit.

If the power protection still shows then there is an internal fault, usually a short or a component defect.

If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.

Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

Cheers

Power issues: will not turn off or function


Unplug all of the speakers and power on.Its possible that one of the speakers is causing the protection circuit to activate.If powered on and subwoofer works start reconnecting one speaker at a time( after powered off) and retest each time.One Speaker may be bad.Its also possible the output ic is failing under a speaker load.There are no fuses related to this issue.If its not a speaker problem then the subwoofer will need to be serviced.

Disc Tray Won't Open


I have contacted Venturer Electronics Inc. (which have recently purchased RCA); they are in Toronto, Ontario. They suggested to perform a Manufacturer Reset (as follows); and if it works; system should power up [this means there was a glitch in the software]...(this usually happens when system is plugged into a power bar or surge protector) if not, contact them @ 1-800-721-4007. They honor the manufacturer's (RCA) 1 year warranty... with receipt.

To reset Unit:
Unplug Unit from AC power (other wires can stay connected)
Press the On/Standby button in front of Unit 15 times
Wait 30 minutes
Replug Unit to AC power
Press the On/Standby button to power up unit
Wait couple of minutes for unit to do its thing

**If unit works properly, then ensure not to plug unit into power bar or surge protector, keep plugged into wall.
**If unit will not power up properly, contact them for further instructions.

Hope this is helpful....
My Unit powered up wonderfully and is currenlty working like a charm.
Good luck!
