Mitsubishi WD - Recent Questions, Troubleshooting & Support

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. https://homenol.blogspot.com/ https://electronicshelponline.blogspot.com/ If blinks continue without any pause, or the LED light stationery; the main board is faulty.

My WD-65C9 is doing the same thing. I got the update and it did not work. Only make sense, why would an upgadre fix a problem, it would give you more features or fix color problem that have always been there, but to fix a lockup. I think it is the mainboard from what I have read on the net.

9 PERCENT IS YOU MAIM BOAR

Ur tv does nt support 3D. U can still see 3D if connected to PC. With power DVD 11 u can able to watch anaglyph 3D.Dnt get confused any standard screen (e.g. CRT (big boxes with curved screen)) can view anglyphic 3D content.

I had this same exact problem with my WD-62627. I got mine to work by re-initialing the tv. I could not believe this worked. Try this, 1) turn on the TV
2) press MENU 2,4,7,0 then ENTER
3) the TV should INITIALIZE
4) Press the front reset button on the front of the TV.
5) should work again....if so.....
6) email me at [email protected] to thank me. :)

Yes, it is located on the back of the lamp housing, you take the screws out of the fan duct and move it out of the way then there is a screw at the bottom of the thermal fuse on the back of the lamp housing unscrew it and pull the thermal fuse up and it will come out install a new one then put it all back together.

Buying a new TV would save time most definitely, if it's in really bad shape the repair costs would add up pretty huge. Buying a broken TV with an intact screen might work as long as you can prove it's exporting signal though. If time means anything, and you have experience in engineering, I'd say go with buying a broken TV, otherwise based off your description, just buy a new system.

I would first suggest checking where lamp plugs into the two pins that the replacement lamp went in correctly----it is not uncommon for it to push the contacts away (not engage correctly) and you will be able to see this with the lamp removed---red should be lamp light failure and most of these have a self check button sequence based on actual model number.

Press the System Reset Button which is on the RHS on control panel If the TV fails to respond to the remote control, control panel buttons, or will not power on/off, press the SYSTEM RESET button on the control panel. The green LED on the front panel will flash quickly for up to one and a half minutes. When the green LED stops flashing, you may turn on the TV. Recent setting changes you made before using SYSTEM RESET may be lost. If that fails try pressing and holding the menu button for 8 secs user manual is here: http://content.abt.com/documents/19051/WD_C-735-736-835-series_om.pdf

When tv goes out, press the menu and input buttons. The green light will flash with a 2 digit code.

Can you try this and post the result(s) here? - When the TV is OFF, Press & Hold the "Power" button for a bit more than 30 seconds. Please post the result here...Thnx

remove the lamp and check to see if its ok, if ok replace lamp thermal sensor

My guess is that it is not economical to fix as it needs new screen. Unless it's under warranty but then you would not be asking. I had an off brand tv that I sold at my Radioshack franchise year ago. I had a customer get a tv with one white pixel constantly on. I replaced it for him. When I called the mfg, they informed me that this was allowable error in the b grade displays they used in their TVs. I quit selling them and put the bad one in my Rv. Still ticked me off when I watched it

did u by any chance open the assembly of the tv and touched the pcb board... the circuits on this board r very delicate and u shud be very if u r handling tis....

wen u switch on ur tv r u able to listen to any sound or wat?
if yes reply back, i wil help u

Yes it is. It's a cheep fix. The fans are on ebay. If you have the manual for the TV. Look in the specs for the TV and locate the fan. You will see the voltage and rpm of the motor. Most likely it will be a 12v dc fan. It has two to four screws holding the fan. And a small plug. I hope this helps you in some way. THE CB SHOP OF COLEBROOK NH. Via Facebook.

try blowing out the set and especially the three fans and the area around them---seen a number of these where a dirty fan will slow down just a little and even stop set from coming on at all or shutting down sometimes.We usually roll them outside and with a aircompressor clean the set out, it usually looks like a dust storm.I have had more than a few brought in that would not power up and as soon as cleaned outside, came up and worked.The actual air intakes are on the front of the set and dust gets sucked into the unit.
