RCA RT2870 Theater System Questions & Answers
Subwoofer not working
The subwoofer is normally the main power supply for the other speakers. When setting up the system, there is a set up guide which allows you to control the power supplied to each speaker. You may have inadvertently set the subwoofer to have 0 output.

It will turn on with
It really shouldn't matter what inputs are attached but...
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.
When you turn it 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?
