Question about RCA RT2500 System

1 Answer

DSP settings not being saved.

I had a problem with the buzzing and changed the capacitors and that fixed the problem. Now my DSP seetings aren't being saved when I turn off the receiver.

I.e I set the DSP to club, turn off the receiver and the DSP is off and the prologic is on. Before I changed the capacitors I could have the DSP set to whatever and when I turned the receiver on it was still set.

    No, I'm turning it off with the remote or the power button on the unit. The remote is the original remote.



    I suspect it has a writable eprom that got burnt out but the fact that the only thing not staying set is the DSP settings leads me to think it's not that. It doesn't matter if I set the DSP to club, theater, arena, etc. When I turn it off and then back on it's always reset to the prologic setting. Plus all the other settings are being saved. Like the bass and treble settings, speaker volumens and settings. The digital.analog audio setting. These are all staying the way I set them.



    I'm not an electronics person, but I know enough that if someone tells me what to replace I can replace it.

    Hi there Flux690, are you turning it off at the wall?

    Does it have a super cap for mem backup. These caps fail frequently. 5 volt, often 0.05 Farad in capacity, they are recognized by their shape, about 4-5mm think and diam of 5 cent piece. Check the voltage across this cap after being turned off. Replace it with one out of another junked unit to keep the cost down.

I think you've answered your own question, circuit power is not going from one side of the DSP chip to the other and that suggests that the DSP's core is at-least partly DOA. You are indeed correct that functional power should be at 3.3V and yes 0.3V does make a difference to the components that rely on a 3.3V feed, however if the DSP is fried you are not going to see normal functionality or be able to diagnose further.

No sound, just a Buzzzzzzzzzzzzzzzzzzzzzzzzzzz!!!!!!


As I found somewhere on the internet; there are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #: 272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will probably last forever now.

I cannot get the functions on the remote to operate.ie pbass dsp/eq etc?


The P.BASS function is only available with 2 channel LPCM sources such as mp3,Divx,cd
and wma. Press P.BASS button and "POWER BASS ON" will be displayed on the screen.
The P.bass does not work with DSP/EQ or DOLBY PRO LOGIC ll modes.
If you press P.BASS in the DSP/EQ mode, the DSP/EQ mode is automatically shut off and the P. BASS function comes on.
The DSP/EQ function is only available in STEREO mode.
Press the PL ii mode button to show STEREO on the display.
This feature works with CDs, MP3-CDs, 2 channel DVD-Audio, DivX and Dolby Digital discs.
When playing a DVD disc encoded with two or more channels, multi-channel mode will be selected automatically and DSP/EQ function does not work.

As far as installation instructions go; you have to have some soldering experience, first. You will also need some type of de-soldering device, be it a solder ****** or solder wick to remove the caps. Make note of the polarity before removing. Then it is just a matter of popping the new ones in (they are slightly larger than the originals so they might not go all the way down flush with the PCB) and soldering them back in. Make sure you do not make any solder shorts or your system will be toast! Your unit will be as good as new and will probably last forever now.

Continous Buzz/Pulse from speakers No other sounds come out


Sounds like you have an open filter capacitor. Your gonna need to look at the b+ and figure out what cap is bad. A circuit diagram would assist you in this repair. If you have no experience with electronic repairs then your gonna need a pro to assist you with this as there are no user replaceable parts inside this unit. Sorry Man. Good Luck
