My CVP-207 is 4.5 years old. It has developed two problems. I would be interested if anyone else here has had similar problems.
LCD FADING
The first problem is that the LCD screen image is fading -- it looks washed out. Changing the contrast and brightness controls does not help.
What is odd is that every now and then, when I press a button or press many keys on the keyboard, the screen will flash back to its normal higher contrast. This does not seem to be mechanical (a loose connection). For example, pressing on the background area surrounding the buttons does not cause brightening. But pressing buttons or keys themselves sometimes causes brightening.
PHANTOM NOTES AND SOUNDS, THEN CRASH
The second problem is much worse. When playing, I start to get "phantom notes". It is as if someone presses random keys which have random sounds and random volumes assigned to them. Then within a few minutes or even a few seconds, the LCD screen goes blank and there is a text-only message: "Unexpected error! Turn the power off and on again. hisysdwn.c /133 /8C1B1E14". Obviously the operating system has crashed.
The last note(s) played continue to sound until the CVP-207 is turned off.
Turning the CVP-207 off and on temporarily fixes the problem. However, depending on how long the Clavinova has been on, and on the number of notes played, the problem will happen again:
:RIGHT: If the Clavinova has been off for a while (cooled down), then I turn it on, I can play for perhaps 30 minutes (about 6 notes maximum at any one time) before the problem appears.
:RIGHT: If the Clavinova has been on for a while (warmed up), the phantom notes and then crash happen in about two minutes.
:RIGHT: If the Clavinova has been on for a while, AND I play back a pre-recorded song AND I play along with it (more than 6 notes being sounded simultaneously), the crash can happen in as little as 15 seconds after starting to play.
OTHER ASPECTS OF THE CRASH PROBLEM
This problem came on suddenly -- it just appeared one day. It has continued for the past month; I was kind of hoping it would disappear just as suddenly!
I cannot recall any changes that might have caused it (lightning storm, inserting a new disk with a virus, etc.). The CVP-207 is plugged into an uninterruptable power supply with surge protector so even if power goes off, it will stay on for a while.
I called a local authorized repair shop. They have ordered a new CPU and LCD screen. Fortunately, the parts appear to be under warranty; otherwise, it would be "about $1000".
After the parts come in and are replaced, I'll report on whether that fixes the problems. Again, if anyone else has had similar problems, I would be interested to hear about them.
