3 lights flash and TV will not turn on

Since your TV is a DLP, it could be the lamp or the color wheel. The flashing lights are a service code. Some TV manuals will describe the code and others require a service manual for the codes. Either manuals can be found online at a reasonable price. Here is a site I use.

My sharp DLP allows for the user to replace the lamp pretty easily so there is a chance you could be able to replace yours if that is the problem. The color wheel is a different story. That will probably require a service technician.

Good Luck

65dr650 color wheel

It is in case next to the lamp. Its thin cable sticks out from the case. You will to open the back panel of the TV, check for cables, remove screws for the base on the right, then pull out the base out. You will have to be very careful removing screws and gentle when replace the color wheel. Hope this helps.

Sharp 56dr650 Dlp colorwheel for Mike miaer

I have a Sharp 56dr650. The color wheel bearing failed. Sharp cares not for its customers and won't even respond to my pleads for help in obtaining the replacement. So, with that said, I went to ebay and bought a vizio color wheel (Omega TV in Hollywood, FL). Color wheel is incorrect and colors are all blue as is, so I pulled the color wheel off and did the same from the old one-BIG note, the wheels are glass and fragile, DO NOT BREAK the old color wheel! I viced the old bearing and carefully worked the shaft out of the bearing (it is snapped into the bearing). The vice distorted the old bearing but it was trash anyway. The new bearing, I broke the new color wheel off and viced the shaft. I then pulled the old bearing from the wheel. I then carefully push the old shaft and color wheel into the new bearing (you will know when it snaps in place) asserting preasure ONLY on the metal center hub with my thumb. I had to file a new slot on the cast housing as the ribbon connector is about 1/2 inch shorter on the new bearing. I installed and it all works great!!! Saved from tossing a $2,000 plus tv out! SHAME ON SHARP! Never buy another Sharp product!

My TV loudly hums when I turn it on

Ok, I just picked one of these babies up this past weekend. It was cheap, so I didn't bother with the research once i saw that it powered on and seemed to work.

It was sold very cheap because it was throwing codes, which the previous owner was told was a cooling fan. Due to my computer hardware experience, I decided to trace what the problem was. The 2 accessible fans were working flawlessly and silently, the 3rd fan (going to the input components) was stopped due to dust bunnies. A can of air and a complete cleanout solved all issues with the cooling fan codes. The loud annoying hum is the motor that turns the color wheel. Since I had everything out of the TV anyway, I decided to trace the sound which is actually behind the color wheel and sounds more like a bearing or mis-balance in the spinning motor. The color wheel itself is in perfect condition.

In the meantime....annoying hums are fixed simply by turning the volume on your tv or sound system up - it's barely noticable during normal operation and is only really annoying when initally turning it on.

Hope this helps someone.
