    Yes that is the fault on my Yamaha CPL130 and I agree it is likely to be digital. What is my next step to fix the problem?

I think you must also ensure that there are not varies at AC line to power supply.
Utilize power outlets that are on different branch (circuit breaker or fuse) circuits or install AC line filter/s.

Intermittent failure of some of the keys could only mean that you need to clean the keyboard from within. another possible remedy for this is to have it serviced as there may be faulty chips.

Well..that is caused by one of three things

a. the sound board(really a digital one) could have some glitches on those keys.

b. the tone recognition firmware, which looks for particular 'keys' may need to be revised and updated

c. is it the case that all 'C' and F# are bad, then it's most likely digital and not mechanical..

please confirm actual failure mode..

The AV amplifier cannot be switched on by pressing the Switch-on button. It just shows a blue light and goes back to standby mode with a clicking sound (a relay failing to energise)?


I would check the capacitors. If any have raised rounded tops then they are blown and will need replaced with the same value. Attached is a photo of blown capacitors. The ones on the right are blown and bottom left appear to be ok

How do I get a teac ag-55manual


There is not much to it. All you will get is a 2 speaker stereo audio. You need to be able to get the stereo audio output from the TV and with 2 RCA cables connect the red and white connections from TV to the TV/ VCR in connectors of the Teac Receiver. But I doubt you will get this output from modern TVs. They usually provide digital or optical output connections. Make sure you have selected TV mode at the front piano key on the receiver.

Hi, i have a sharp cd-ba2000 compact stereo system and when i put the plug on, on the display appears the word "protect" and there's nothing i can do to make the whole thing work... can u help me...


Please see the link below for an explanation of protect mode. Specific to your unit, there is an AMP-PAC IC that is likely defective. This part can be anywhere from $60 to $100 for the part. I can look up the part and its availability, but this is not typically a DIY repair. Further investigation inside the unit is necessary to determine why the unit failed.

memory. For details on what will be cleared, see
“Clearing the receiver's memory” on page 15.
• There will be no sound when the demonstration mode is
activated.

and...

Note: If the AC power cord is disconnected for about two weeks, the receiver’s entire memory will be cleared and the demonstration will start.

We just bought a new 52 inch Sharp LCD and the right speaker is muffled. Is this common? How do I fix it? Should I just take it back?


If the set is new, don't waste your time trying to diagnose the problem. The sound should not be muffled. It can be as simple as a piece of sealing foam that has moved during shipping, but return the set for warranty exchange. It should not have failed this soon (or at all!).

I have a Roland HP2e digital piano and one of the keys has lost its touch sensitivity. It works initially but when it passes a certain threshold of loudness when played it goes to full volume on that key...


Just managed to fix key loudness problem on my sister's HP-2E after talking to the local Roland Service Center. Basically I had to remove all the rubbery strips under the keyboard, clean them and clean all the contacts on the keyboard PCBs with CO contact cleaner. Not a trivial procedure - 80 or so screws to remove and replace and a lot of parts.
It has completely solved the problem (apparently its not unusual on any keyboards). I have posted more details and a couple of pictures on my blog (http://web.me.com/iain_sommerville/Home/IainBlog/Entries/2009/4/20_Piano_Repair_2nd_Attempt.html not sure if that is a permalink - if it doesn't work go to http://sommerville.info and search for HP-2e).
A roland service center can fix this as well however it is pretty time consuming so they will charge you. They can also sell you replacement keyboard contact strips if cleaning them doesn't work. Hope this helps

Clavinova electric piano keys easily stuck and slow to raise on it's own after pressing a note. How can I fix it myself? Thanks, Marcel


by any chane a liquid has spilled over your keyboard? it's kinda hard to dismantle that keyboard. but it can be done. i wonder only how it could get sticky as you described. i am from yamaha service before and i have seen the mechanicsm of clavinova, it should not go like that except if you had spilled something on it.

P-200 piano some keys are louder than others


Hi there marklyster

The keys are all touch sensitive. Generally speaking, there is not alot to go wrong in this area. They key contacts may be dirty creating the problem you have.

The keys are not as heavily weighted in the treble cleft on this model, could this be causing the problem. If it is certain keys that are affected, then I would suspect a contact problem. You may need to have the keyboard serviced.

I have a Wurlitzer Omni 3000 organ that was given to me. When I turn it on, everything lights up but not getting any sound except in piano mode. With volume turned to maximum, you can very faintly hear the...


Hello!
I had several friends over the years who've had Wurlizer organs and they always "swear" by them. Guess they would be somewhat like Maytag products.

Anyway, I called one of them and she said she finally was able to get a partial solution from a friend of hers.

However crazy this sounds, she assures me that this procedure helped:

Look on the middle of the back of the organ, equidistant from corner to corner. There should be a knob of sorts which is kind of gold or bronze color. If the numbers haven't worn off, they should be around this knob. She said it works like this: turn the knob three times to the right, then four times to the left, and then push up. This supposedly resets the mechanism inside the organ that was loosened when your bench contacted the big pedal.

It's certainly worth a try, isn't it?

Intermittent audio output


It's quite possible one of the relays is failing that is part of the switch between audio output choices.  Do you notice any output difference between a certain output (i.e. dvd, tape etc)or is that point arbitrary?
