Question about Televison & Video

1 Answer

I have a Sharp 56DR650 rear projection 56" TV. The color wheel has already been replaced two years ago. Tonight the TV stopped abruptly with a small clink sound but with no whirring sound like the wheel failure before. The code blinking is three green, two red. I have not pulled the bulb yet to see if it failed. It is too about two years old.

    The diagnosis was correct as after I posted the question, I pulled the bulb to find that it had exploded internally. The new bulb is ordered.

I would start out with the Lamp. Lamps only last between 5,000-8,000 playing hours so if you play TV 24hrs aday or alot chances are you need to replace Lamp PN# ANR65LP1/1
Sub/Part# 9NK3797094200.

Mats Electronics has Lamps for $99.00 and up 1-800-628-1118

Also Look on Power Supply board for Bad Capacitor It will be vented or Puffed up on TOP, 180uf 250v, This Cap[aciotr has been know to be bad cause TV to shut off and only clicks when TV is being turned on.

The tv will not come on . The power led is blinking 3 greens and then 2 reds. I have changed the light but still can not get the tv to do anything. I can't even shut the power off with the buttons.


Most likely its not the lamp thats bad but the color wheel is stuck. Check if the color wheel starts or not. You can make this out from the typical dlp switching on whine. If you have already changed the lamp, and there is no color wheel start noise, you have a bad color wheel.

Loud Buzz


loud buzz is the color engine, turning the color wheel. Find instructions on how to take it out and clean it and that should fix that problem.

56" sharp 56dr650 rear projection tv


Hi - wanted to let you know that I have the same problem and I contacted Sharp (800) 237-4277. They offered me a prorated exchange. Select #1 prompt for Operations and then they will create a case number if you don't already have one and then send you over to the Disbatch Dept. They are picking up my 56" TV and are selling me a LC52"D65U for under $450 current retail value of the new TV $1900. Give them a call and see if they can work out a deal for you too. The whole transaction will take 7 - 10 days. Good Luck!
