by: Gigs

Hi Guys. I have done the cap on the Dm pcb for the initialization problem(sorry for the spelling) It worked great but a new problem/s has come alight. When i layer with strings at some point its as if it just starts to hang, it stays on the last notes played and just before it does that it starts to crackle. Probably a loose/dry connection but before i start resoldering all the pcb's, do you think it might be the DM pcb that is starting to go? Thanx for all the info on here. It helps when someone knows what theyre talking about.

starstarstarstarstar 		Distorted sound from Yamaha psr2100
by: Muralidhara

My keyboard produce distorted sound especially in the left hand keys in accompaniment section. One may be under the impression that keypads below keys may have dirt deposited.but strangely it happens for some styles and works fine for some styles and voices. One can take a chance by replacing all the capacitors One by one and each time to test the unit.To make the above statement,i have an experience which proved fruitful.
In addition to above issue, my keyboard had initial booting problem indicating assertion failed, pg 133 bla bla ....
I checked with you tube videos and found that one capacitor in the processor board(no.C116 of rating 18volts
, 47 micro farads, electrolytic type) would be faulty. I replaced carefully and to my astonishment, problem got resolved.I will try this myself when problem aggregates.
It's always a capacitor which gives away over a period of few years. other components will not deteriorate.

by: Alfred

Dear Tim: Thanks for update and good news. If by any chance the guy who's going to fix your unit tells you what he did, it would interest me personally as a tinker. I'm really glad you've found him. YOU are a MAN OF YOUR WORD in submitting the followup. Thank you. I await your next post. Regards.

I did a complete testing using the unit and found nothing. I did talk to yamaha and they told me it is usally a problem in the prosseser board. I did get some repair shops from them in my erea and was quoted base prices of $71 an hour and they figured 2 to 3 hours work. For that price i will do it myself. But as good luck would have it i found a local keyboard repair shop on craigslist. i called them and he already new what the problem was and had fixed many 2100s already. he is charging me $50 and will fix it while i wait or go have coffee somewhere for an hour. hell my own time is worth more then that to tincker with this. he said it was a bad solder joint just as i thought. he did not go into detail but i will update when it is fixed.

I am going to call yamaha here today and find a cheap repair center. thanks for all the info guys and please send more. if anyone needs this manuel let me know. Tim

starstarstarstarstar 		Fuzzy sound
by: Mike Burke

Hi there.
About your distorted sound. As it comes and goes, or rather came and went, you may have a dry joint at a de-coupler capacitor in the sound board feeding the speakers. This capacitor may be part of a chip so it won't be mounted on the board.
This can be a very tedious search and I would advise that you leave it in to be repaired by an expert technician. It will be well worth the expense. I have a PSR 2100 and it is a great keyboard, and may I say you sure got a bargain.
The repair will probably cost at most $50.

Well I worked on it a little bit and cleaned all the rubber pads under the keys. they really did not need it but since i started i figured i should just do them all. It was pretty simple to do. If anyone ever cleans the pads under the keys do not take an eraser or any kind of solevent to the board contacts. You will ruin them and they will not work. just wipe them with a clean soft cloth. If you have rust or dirt from spillage use contact cleaner with a qtip and very little of it. do not use alcahol. I know i did not spell that right.back to the 2100 i did notice when turning it over while plugged in it would start to work right. then when move it would go bad again. So I am convinced it is a bad solder joint somewhere. It must be comming off the sound board. i wish someone had scamatics for this unit.As of know i don't think i need parts i just need information and time to trouble shoot the problem erea. I did find 2 connector ribbins not fully pressed into there sockets. Sloopy work for such an expensive unit. Alfred I am getting this going for my son whom is in a band he's 14. He played piano for 6 years but also plays a mean guitar. There band is pretty advanced for 13 and 14 year old. They have real talent. i play guitar also since 13 and he is better then me already after playing 4 years, go figure. there on you tube under the band (unoxidized). they have played many gigs already and make all there own music. So we were trying to connect the 2100 to a mac ibook with no luck. So know another problem to figure out.he wants to record with the unit.

by: Alfred

Dear Tim: Yes, you could be correct about a bad solder joint. It may have failed completely breaking continuity in the intrnal circuitry. I don't have to remind you that while poking around the components some may be static- sensitive, so watch what you are doing. Anyway good luck and keep in touch.

Thanks for the help and yes I will keep reading post maybe i can help someone. I had another thought on the pads, I do not think that is the problem because when I run the find music or any other automated music it does the same thing without pressing any keys. there is a guy on PSR Tutorial whom had the same problem but never updated what he found. that is very important information since many most likely had this same problem. My thoughts are know kerring toward a bad solder joint somewhere.maybe in the sound board. Tim

by: Alfred

Dear Tim: Thanks for fast reply. I have a selfish interest in what you and your friend discover, as I'm an electronics tinker. Furthermore, there are other members who might also learn from your eventual analysis and repair.
We look forward to your news, and I hope you get a good bid on your Roland.

by: Anonymous

I will take a look at that. But it almost seems like a power problem somewhere. I did contact yamaha to get there thoughts but have not talk to them yet. Waiting for a call. But they did leave a message but i don't think they will be much help. I am going to trouble shoot it with a friend and start testing boards and the power inside the board. I will bet some part on a board is bad somewhere. Then again yes it could be the pads being dirty. I don;t think they are bad as the unit is mint and looks to have been well kept up.Since I bought this i was thinking of selling my Roland E5 so i put it up on craigslist i hope this Yamaha is not alot to fix. As my Roland is like new.Tim

Dear Tim: One POSSIBLE (maybe probable) point not mentioned are the rubber pads under the keys. They could be dirty/deteriorating. If they have to be replaced, contact Yamaha Parts Department at (714) 522-9011 or 1 800 940 8806 to place an order over the phone via credit card. Visa, MasterCard, or American Express. Be sure to have the Model number of the product available so that accurate information can be provided. Good luck, and come back often to this Forum. We need active members with your "smarts" Good luck and keep well.
