20 Most Recent Mitsubishi WD-65C9 65" DLP HDTV Questions & Answers

Suspect the bulb/lamp has failed. If you didn't get the factory replacement the cheap ones sometimes only last or a few weeks, unfortunately.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Hi,

I am Sorry to Hear regarding the Problem.

From the information you have provided the problem is being caused by the optical block. Sorry to say replacement of the optical block is the only thing that will correct the problem. You are looking at a $1000 to $1500 repair if the TV is out of warranty. Sony had the same problem with their DLP TV sets and extended the warranty to cover the repair. You might want to call Mitsubishi and complain about the problem. Persistent consumers can often get the manufacture to cover at least part of the repair cost.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

check for capacitor burned out and replace it

Sounds like a failing DLP chip.

You need to replace the main board, call Mitsubishi help line, they did not charge me a dime (If your TV is less than Yr old)

Hello,
There is a software update that is available for some Mitsubishi dlp models. The wd-65c9 is one of them. When I experienced your problem, I went to the website, downloaded the update, and installed it on my tv and boom, its fixed. It's super easy, free, and takes a few minutes.
