Question about Audio & Video Receivers

Open Question

I have a roland rd-250s with a dead g and a flat in the 2nd lowest octave. I have had filaments replaced and keypads adjusted in the past. The usual charge for this service is prohibative. I need to learn how to open the keyboard (keys, keypads, filaments, computer boards, encased above metal) so that I can adjust keys/keypads, repair/replace filaments.

    this is a digital piano, not a receiver. If you have someone waiting to teach me exactly how to open the actual key/hammer assembly and isolate the filament/chip/pad/key assembly;diagnose problem with g/a flat, repair or replace worn part as necessary and reinstall to restore to working condition then I would define my problem as solveable through you and upon receipt of some good faith effort to inform me that you do, in fact possess this solution in contrast to 'you might have some basic tips, for example, then I will consider actually paying your $10 fee if necessary. I appreciate your services, however, the point of seeking online help versus taking my equipment in person to a repairman is not to spend money I can scarcely afford. I understood your premium offer when I read your site and posted my problem. Had that option deemed valuable to me I would have taken it. Your prompt made me wonder about the validity of your forum versus your paid information, and titling my problem as a receiver is inaccurate entirely. I have and plan to use this device for quite a while so if any of you can impart this information to me please respond in some specific manner which relates to the issue. Thank you, I hope you smiled a little, and I really will appreciate the help.---cc

Roland RD-300SX has no sound output unless foot pedal is depressed.

Make sure that the pedal is connected to 'DAMPER' and not 'CONTROL'.

I have an rd 7103. Just moved. Hooked up again and no sound. Reconnected every wire several times and no sound even through the headset. all functions on the remote work even the aux outlet ?????

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead

I need a replacement woofer for a Roland DS90-A 24 bit digital studio monitor. Serial # BT46344

If you want an exact replacement you will need to contact If you want to replace the speaker yourself you can contact (out of Cleveland Ohio USA). they stock many speakers in all sizes and prices, but they are a wholesale company so the prices are very low. I suggest you replace the woofer in both of your monitors though so your sound will be balanced. besides if one speaker has malfuntioned chances are the other will soon anyway.

My Sherwood RD-6105 shuts off if I turn it up past 28 or 29 db (which isn't very loud). I'm using it in Dolby Digital mode. It even happens when I use it with my components that are analog. This just...

It's acting as if a short or near-short exists on the amp outputs at medium levels.

Disconnect one of your speakers at a time and try it. Make sure your speaker wires are tight and not shorting to anything and all channels have 6-ohms or more load.

Concerning my Sherwood RD-7500 6.1 Channels Receiver

That still doesn't make much sense. Please slow down and say what you mean with detail and accuracy. We're not mind readers. You are our eyes and ears.

Is the following true?

"Video 1" video output goes to the TV and works ok. Though it is irrelevant since you don't have a video problem. That you mention it at all is distracting. Do you feel it is important?

Tower speakers are the main or only speakers. Do they work ok for other sources?

So, to be clearer, you have a problem with a particular sound source (the game console) being less loud than usual. Is it unusable or drastically different in level than other sound sources?

Where and how is the game console connected for audio? Can you move it to another input?

Have you considered that the game console or its settings may be the reason volume is lower than usual?

Hear sound but cant get any real volume even at full blast

I was playing around with my Sherwood RD 6513 and adjust the the output level to its maximum, amongst other settings. This limited my output on the amp to a maximum volume of 65 not 90+.. Anyway i pluged in the microphone and done another 'auto setup' of the volume levels and distances, and this allowed the volume to exceed 65 again!

Also if you have an external source such as a DVD player - i would assume you have already checked its output volume setting?

Yamaha B5CR organ... 3 notes in each octave are not sounding

Open up the top cover and check the tone generators (12 little black "barrels"). There are 12 generators in total, one for each note in all octaves. Try to adjust trimpots on the generators.

The Output Volume Is Extremely Low!

Sometimes the rear channels can be used as a 2nd zone. Does the unit have A&B speaker selection on front panel? Usually if it has a 2nd zone it will say in owerns manual or on back of unit or on front panel as well. That is when you have the option to adjust the volume in the menu on the 2nd zone. GURU JAY

Led display goes dead

I suspect intermittent 31V supply, filament supply or bad connections on fluorescent display.
Check Q801 31V reg , R802, zener on base of Q801 located on DC board. Inspect all boards for bad solder joints, reflow and tighten pcb grounding screws.
