Rca rt2390 lost remote 5 years later lost electricity reciever reset and no optical input designated cannot designate optical to input source without remote...help

Hmmm, lack of ventilation, shorted speakers or wire, excessive volume?

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 '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.

Hi

wait a moment pls

wait a moment pls

put source on SAT. use the remote and hit "set up" use right arrow button until the word "coax" shows on unit, Now your digital.

Good Luck

If I'm Correct There Is Only One Set Of Inputs On That Model TV. What Inputs R U Reffering To?

Depends on the capabilities of your un-named components and what your intentions are.

Do you want the TV to be the audio source? As TV's are not the best sound sources, being designed to just make high-quality flickering visual images with passable audio accompanyment, this is NOT the optimal way to go, but it is do-able. You know this. Run its RCA audio L and R Outputs to any available RCA AUX Line Level Input on your system.

Do you want to hear TV-related audio on on your audio system? This is HIGHLY recommended as it tasks the specialized audio hardware to deal with the audio while bypassing any handling of the video. You can still run your vanilla analog RCA pairs between Cable Boxes and/or DVD's to the TV if the TV has sufficient audio inputs AND you can run the nice digital audio outputs of those video-producing sources to your HTS, if IT has sufficient digital inputs (*).

>>>> * A word on coaxial vs spdif (optical) audio cabling - I always use coaxial if I have the choice because it is A) cheap RCA cable availabel anywhere in any reasonable length you want to run; B) can be extended and SHARED with other components if you have limited jacks available. You just have to be careful to make sure only one digital source at a time is turned on while using the other; C) RCA cable is impervious to problems arising from tight bends; optical is too delicate and won't work well when bent. <<<<

My $.02:

My system is set up this way for one main reason: it allows casual TV, DVD/Blu-Ray watching (News, Weather, Imus in the Morning, etc) without the full-blown power-hungry audio equipment turned on at all.

When I want to melt the paint on my listening room walls I can also fire up the audio stacks and go ballistic with Top Gun on Blu-Ray, for example.

I never could understand the prevailing design goal of AV receivers and HTIB's to collect all video sources to a single point (of failure, possibly) and redistribute them to the TV or monitor. By design, that means you have to have the audio equipment turned on at all times to watch TV. Not very power-conservative and who needs hi-fi surround to watch Regis and Kathy Lee on live TV or Dave Chappelle on DVD?

I have found that on some units you unfortunately need the remote for more advanced settings. Sorry man.

the problem is that you need to select the source on the remote of the unit and then select setup, you will be able to change the source from analog to digital (i don't remember the setting) and voila! it should work

Hmm. let me see if I get U correctly. you use u'r theater system with a TV and the audio is fed via optical or U have DVD player that you can feed the audio via optical or coax. I think it is the later, if it is U could be having trouble with sound decoding setting of the DVD player itself. It's like mpeg out or PCM out instead of full DTS or 5.1 dolby digital decoding. If this is the case just use u'r dvd remote and check the audio play back settings. If this does not solve u'r problem, pls state u'r set up briefly, so tht I can understand the type of connection u use. Happy troubleshooting Rifaa

your system needs to be servicedtake it to a tech and have him clean it up.
