WS-65815 Not Responding

Hi, I have a projection TV model WS-65815. It does not respond to remote control or front panel. I have tried unplugging and plugging it back in. The light flashes normally (fast for 70 sec.) and I can hear the fan working fine as well, but it still does not respond. I have tried the reset button also. I held the device and menu buttons for 5 seconds to display an error code (if any) and it gave back a code 12 which means no error was detected. I have taken a look at the circuit board, but do not see any visible issues with the capacitors or anything else out of place. I find it strange that it was working fine one night and the next day it would not turn on at all. The problems started when the TV would freeze when I pushed the Device button on the remote control to try to put a DVD on. The sound would continue playing on the channel I had it on, but the screen froze until I turned the TV set off and turned it back on. The menu did not display at all. It simply froze the instant I would push the Device button. Any suggestion as to what it could be, or is it really necessary to take to a technician? It is a heavy TV and difficult to transport about 20+ miles to the nearest repair technician. I also do not want to end up paying more for repair than a completely new TV.

SOURCE: green power light will not stop flashing and tv will not turn on or off

You need to replace the 1000uf capacitors on the DM board thats the classic symptom of the DM caps being bad the light continues to blink repeatedly. If you need more info on the repair let me know.

SOURCE: My Mitsubishi WS-65511 won't turn on.

I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

You need the WS55909 - WS73909 DM kit. You can get it at the following link which contains the capacitors and the CD with instructions on how to do the repair.

SOURCE: I have a Mitsubishi WS-65909 w/a steady blinking

Only one of two reasons for your problem--either the DM is bad OR:

These sets sometimes develop a problem with the front keyboard---micro switches in back of the plastic buttons can fail (reset one is common).

Remove front speaker grill and inspection plate behind it and follow the group of wires coming down from the front keyboard to the right top edge of the opening.

About 8 inches to the right you will find two plugs that are inline--they go to the keyboard--disconnect both and turn set on with REMOTE (remote receiver is behind the screen).

If the set now functions you have a bad micro switch on the keyboard (most likely the reset) and two choices---either leave the keyboard unplugged and just use the remote or remove entire screen and get at the circuit board and locate and replace defective micro switch.

Lots of people miss this as a possible choice--easy to do to either know it is the keyboard or not.

If set does not operate this way DM is bad regardless of how caps look.

Clean/Tweak Rear-Projection MIT WS-65815


There are really only two things that need to be done for service on this set.

FIRST: with the set unplugged remove the back cover and wipe the three large black lens----a paper towel with glass cleaner sprayed on it works fine.

SECOND: WITH the original remote go into the customer menu and select convergence--select the advanced menu and use the remote to adjust--there will be instructions on screen to tell you what to do.

Some people pay 50 or more for a house call when for the most part it is a do it yourself thing.


Let me know if you have questions--I do this kind of work in my area----15 job.

Mitsubishi WS-55511 not responding to remote or front panel. Tried System Reset Button several times. No luck.


Sometimes the control panel switches on the front of the set go bad.
Try running your fingers across the buttons to see if it helps.
I ended up disconneting the front panel switch board and just use the remote now.

TV is not responding to the remote control.


The set may have defaulted to a front panel lockout. To defeat that on the front of the set hold down the MENU button for 15 seconds and see if it will then power up. I know that doesn't solve the problem with the remote but one step atta time. These sets are prone to leaky switches on the control panel and when that happens the micro cannot accept two different commands at the same time. That could be why the remote is not working.

Tv wont respond because device menu is changing through each device


I had a similar problem: my WS-55511 would not respond to the remote and the front control buttons (with the exception of Power) cycled through the Device Menu. I solved this problem by disconnecting the front panel. Here's how to do it: 0. Unplug the TV
1. Remove the speaker grill from the front by pulling forward: there are no screws. 2. Disconnect the two cables that are exposed after the grill is removed. 3. Plug the TV back in, wait for 5 minutes to reset. 4. Try using the remote.  Hope this helps!

Tv ws-65511 volume stuck


Did you ever get this problem fixed? Ours just started doing the same thing. It worked fine the night before, but today it's doing what yours is doing. The remote stopped working for the TV. The remote still works for the cable box, but volume and anything related to TV function not. The screen flashes when we try to adjust volume or anything else, but resets to previous volume. TV not responding to any commands either on the front panel or remote.
Any ideas? Thanks, Patti
