Weak LCD on Yamaha PSR-E413

by Koen
(Netherlands)

The LCD screen on my Yamaha PSR-E413 is weak. The backlight is OK, but the black LCD shows very weak. Is there an option on the E413 to adapt the brightness? The manual doesn't mention it.
Thanks for any help.

Regards, Koen

Dear Koen: I believe your keyboard is still quite new, and it should not be having any serious problem with its Display. You aver the light is working but that the "text" looks dim. You'd be surprised to learn that it can be just a matter of line-of-sight, and if you lower the bench (or raise the stand) to change your eye level you may find a change. Also, keep any house lamps away from the Display area and move your keyboard away from windows which let in any sunlight to reduce any reflection. I hope these simple actions help, as Display problems are serious, and have to be replaced at some expense. Let's hope my suggestions work, and if they do, please post a follow-up comment in this Forum so other participants can benefit. Thanks and good luck.

Dear Alfred, Thanks for the suggestions. Unfortunately it was not a matter of line-of-sight or bright houselamps. I could only read the display with my chin on the keys. However, when turning the keyboard on the next day, the problem was gone. Hope it doesn't happen again, otherwise I'm afraid I'll have to have it repaired.
Regards, Koen

Dear Koen: Appreciate fast response.Glad to learn the Display seems to have returned without problems.Hope its cured itself. I have trying to tell participants in this Forum, "WHATEVER YOU DO, DO NOT OPEN YOUR UNIT TO ATTEMPT REPAIRS". The innards of these machines are complex and require professional attention when problems such as yours arise. Good luck.

by: Tonny

Hello I got the same problem. Bought mine second hand. The shop were the keyboard was bought (Sol, Breda, netherlands) said that al their keyboards have the same display. When I said why not contact Yamaha, maybe a factory problem. The got a little bit angry?
So I don't know what to do now.

Dear Tonny: Sometimes it's risky to buy used electronic equipment, precisely because defects soon arise. or because sellers tend to brush off any complaints from disappointed buyers. It seems that you may have been the victim of such developments. Your purchase probably had no warranty, and I doubt Yamaha would do much more than suggest replacement of the LCD Assembly, which in itself - not icluding labor - would make the cost prohibitive in comparison to whatever you paid for your unit. You have to decide whether your budget allows you to buy a new unit (with Yamaha Warranty) from a reputable music store, or to find another used unit in the hope it will be in good working condition and making sure you test it before buying. If your budget limits further spending, and you feel you have NOTHING TO LOSE, an alternative is to open the keyboard and attempt a repair yourself. I ALWAYS AVOID SUGGESTING SUCH DRASTIC ACTION. however if you are a HANDY PERSON,go ahead. There is really ONLY ONE AREA TO CHECK. It is where the LCD should have a plug-and-socket Connector. It may have become disconnected or is loose. DO NOT FIDDLE WITH ANYTHING ELSE. or as I hinted earlier, YOU HAVE EVERYTHING TO LOSE. Please post a message in this Forum letting us know the outcome. Thanks and good luck.

Just a follow-up on my problem that started this discussion: the LCD went weak again, so I brought it back to the shop (under warranty). Yamaha looked at it but couldn't find anything. The shop gave me a temporary substitute keyboard. I used my own power adapter, and I had the same problem. I changed the adapter, and the problem was gone. I also never had the problem again with my own keyboard. Looks like the adapter was the problem: it didn't give enough power to fully light up the LCD display.

Dear Tonny & Koen: Koen's post is a wonderful and timely one. It could well be the answer to your problem, Tonny; so buy a new Adaptor and try it out. It certainly is better than opening the unit, and is not an expensive accessory.
Koen: Could you please quickly add a post informing us of the SPECS (name & Model) of both your new and old Adaptors. This way, Tonni will know what to buy, and I will be able to set my records straight. It is obvious that the PSR E 413 Current requirement was not being matched by your old Adaptor, and this may well be the reason why so many Forum members have been having problems with the Displays of their units. Our exchange of Forum posts is truly an excellent example of how well this Forum can function. Keep well, and my best regards to both of you.
