How do I re-attach the power switch?

Is there an easy way?

    Great advise. I was able to access the switch through the front grill and replace the little plastic extension to the switch.
    Thank you!

Pop the speaker grill off and you will see 3 little screws holding the bottom of the screen to the set. Take those out and lift the screen up and out. Be carefull of the cables holding the control board to the set though. You may have to take the front cover off first to loosen the stress on that cable.

Hello my name is Devin, I have a wd-65735 model and I just purchased it off of a friend and braught it home. He had told us from laying it on its side while bringing it home it said in the guide to let it...


Caveat: I am not a tech, I just read through the Mitsubishi service manual, and have worked on different model TV that I have owned (older model of this one) I am a little unclear on the second set of lights but I think the combination *may* indicate that the lamp fan is not starting (there are two fans though), if the blinking red is the status light. It is possible the connector for that got jostled during the trip, something fell into it from being on the side (wire or loose something) and is blocking it from spinning now, or a module unseated a bit,and is loose, or the lamp is no longer seated correctly (though the lamp light does not appear to be on) or none of these. :) These are just guesses.
Be careful if you open it up, due to potential for shock. Wear gloves, and power it down first (then unplug). Reseat any fan connectors.

Google: I used "wd-65735 status lights" to find a service pdf , it's for V39 chassis (several models)

From page 24 of Service Manual :

3. Error Code Operational Check Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Opera- tional Check. When the TV is switched Off, the code automatically resets to "12" No Error.
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds, activates the Error Code Mode. The "TIMER LED" flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must be used, NOT those on the Remote Control.

  • Theflashingthenpausesforapproximately1/2second.
  • TheLEDthenflashesindicatingthevalueoftheLSD(onesdigit)oftheErrorCode.
  • The Error Code is repeated a total of 5 times. Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

A speaker wire on my Toshiba 43A10 rear projection tv came loose when I wanted to replace the speaker, it fell onto the cuircut board and made a short, tv switches on but no pictute or sound


set has a number of pico fuses (up to 7) that are not glass and look like a small resistor and are usually orange, green in color--all will have marked on top of board amperage which is a easy way to find them--have to test them like any fuse (set unplugged please) as they will look perfect even when bad.

Tv wont stay on . i changed the color wheel and bulb and now it turns on then shuts it self off right away and the lamp light is flashing still


When you changed the lamp did you clean the "lamp temp sensor"? When you removed the lamp housing from its cradle, you can access it from where lamp goes. It can be cleaned with a Q-tip.

Also, there is a little blue safety switch that is located on bottom right of the light engine tray. It MUST be in the DOWN position when the TV back is reattached to TV. You can use tape to hold it in the DOWN position while attaching the back of set.

Also after replacing your lamp did you reset the lamp life?, You can do this by:
1-TV off
2-press mute+1+8+2+Power. This will access factory settings.
3-scroll to "Options". Press right arrow to next menu. scroll to "lamp life" hit right arrow and click reset.
4-power off.

That resets the lamp life hour meter.

use solder wick or a desoldering iron from radio shack which will **** up the solder so you easially remove the IC. Radio shack has a in-expensive desoldering iron with a rubber bulb which makes this easy.

Toshiba 65hx81 65" Rear Projection tv. black & white color/green


Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck
