Yamaha Full-Size Keyboard Logo

Posted on Jan 08, 2010

I have a Yamaha YPG-525. Everything is working except the LCD screen. It turns on, but doesn't display anything... I had this problem once before when I didn't use the keyboard for a while, but it ended up working after using for a couple of hours. This time, it just doesn't come back. Any comment?

I have the same problem, mine is Yamaha YPG-625. This seems to be a common problem with Yamaha keyboards. I opened the 100 screws in the back, separated the main board from the display unit which is under it if you flip the keyboard upside down, to verify if there was any loose wires, nothing of the sort.
It is so frustrating, the keyboard is working fine but it is hard to navigate because the display is not functioning. Yamaha should do a recall as this is obviously something wrong with the keyboard happenning to a lot of people

I discovered in reading the first few pages of the manual for the YPG525 that there is a battery that is soldered in and must be replaced about every 5 years. I was told to call a Yamaha Dealer in my area (714) 522-9011 for Denver, CO and get instructions. The other solution was that I had an adaptor gone bad. Needed to buy a new one.

YPG625 Humity problem

The overal sound of yamaha YPG 625 and keys operation are exellent by the price. The only problem I eperienced is the instrument operation under high humidity environment. Under this condition many keys sound loud over others, furter more with no expectation from mucisian. This problems is normal for that model because the music store change my previously YPG625 for the same problem<br /> <br /> Sometime I solve the problem to located the instrument under sun exposure and cover the keys and display to avoid direc sun exposure.<br /> <br /> Another is apply with a hair dryers over the keys. But is very disconform situation, and I dont know if the Yamaha exposed this isntrument under high humidity environment durig the product test. I has a Ymaha very low budged digital piano and Roland controller A33 in the same condition and never eperience problems, only with this model.

I have downloaded Yamaha softwear driver for my PSR 295 AND YPG 525 Keyboards to my Windows XP The files are zipped and canot access them. What do I need to do to open them . And why are they zipped in the...

You need to down load a unzip utility program to open the zip files. You could try this link: http://www.freedownloadscenter.com/Utilities/Compression_and_Zip_File_Utilities/PKZIP__32_bit_.html

The reason they are zipped, is that this makes the files a lot smaller. Smaller files are easilier to transfer, store and to download. The unzip utility will restore the zip files back to their normal size. Hope this helps you.

Window display not functioning

You need to use a transformer type voltage convertor.

DO NOT use the type for converting 220 down to 120 for hair driers.

The voltage should NOT be a problem as usually these will operate down to 100 volts. If the keyboard is sounding correctely, that would indicate there is NOT a problem with voltage.

It is LIKELY that the connections to the LCD were damaged in shipping. There are many, many connections to the glass assembly and if dislodged will have lines across the display.

Repairing this is usually not something one can do unless very experience in electronics.

What needs to be removed from my Yamaha YPG-625 to

DO NOT open the case unless you are aware of and comfortable with the fact that you could _destroy_ your piano. Easily.

Observe appropriate anti-static precautions. It should go without saying that this is an electronic repair, and dangerous voltages may exist inside the case.

1. Remove the stand if you have one
2. Lay the keyboard upside down (bottom up) on workbench
3. Remove all 90+ screws from the bottom of the chassis, including the 14 inside the speaker compartments
4. Carefully lift up on the bottom case part, taking not to damage the speaker lines
5. Unplug speaker connector and set lower case aside
6. LCD is mounted beneath main logic board
9in the center), my problem lies elsewhere, but competent and cautious service technique should lead you where you need. I would strongly recommend replacing the LCD assembly module, unless you are experienced in LCD repair.
