Mitsubishi ws-55511 Sound & Cable picture turns on and off

I just bought a Mitsubishi WS-55511 and had picture and sound from my cable connection. After a period of time the picture went blank, but sound remained. Picture and sound still worked on the Hi-Def inputs. After unplugging the TV and playing with settings the picture with sound came on. Then after a while the picture shuts off. Is there any code combination on the remote that will cause the picture to shut off and leave the sound on?

If you have picture in a picture feature and a button that controls that ,maybe you hit the pic.in a pic. button.It would go blank cause the other source for pic. ina pic. does not exist.Thats just a guess.The this behavior happen when you use a dvd or antenna connection?If so there might be something wrong with tv.Try a different input b4 anything else.

Hi,

DO A HARD RESET: Unplug the power cord for 4 hours. This will discharge all the voltages on the internal eproms. When you power it back up the factory defaults will automatically replace the eprom data. This will correct any corrupted codes.

Of course, this may not be the problem, but could be. So this is a first line check.

WHACKING TEST: Many times these sort of mysterious conditions are a result of loose wiring or cold solder joints. About half of the strange complaints I get fall into this category. While the set is on and while you are trying to address the OSD, bang on the cabinet in several places with your hand or fist. This will jar the set hard enough to restore the faulty internal connection that may have been the culprit.

If nothing pops up by now, it is most likely the controller IC and/or screen graphics driver is defective and needs replaced. This is not related to the picture or video that comes from the program, they are really quite separate.

The cost of this repair could be quite high because it will require a tech to do some clever analysis in order to find out exactly which circuit is the offending one.

I don't think you will find this kind of problem written up in any of the manuals or service books. It is quite strange and really, if a tech is needed, well require one who is a cut above the ordnary one: Someone who really knows how to troubleshoot and analyse and think about what is going on inside. Most Mitsubishi techs are "phone jockeys" the merely call an 800 number and someone tells them which board to replace. They replace until the repair is made and they don't really know what is going on inside - but you get a bill for $400 or $500!

Gooddluck,

Would you like to bypass, defeat or reset your Mitsubishi HDTV Parental V-Chip parental lock? Have you forgotten your V-Chip passcode or password?

If you forget your V-Chip passcode, you can view the locked TV without entering your password.

When your passcode is requested, press the number 9 and the QV button on the original TV remote control at the same time. This process temporarily unlocks your TV.

When you enter the V-Chip Lock menu, pressing the number 9 and the QV button on the original TV remote control at the same time will delete your old password and prompt you to enter a new passcode. Pressing HOME at this time will cancel the entire passcode.


I hope that helps.

How to get laptop connected with vga connector to


Unplug the television. Connect the VGA compatible monitor cable from the laptop's VGA monitor Output to the VGA Input on the back panel of the television. You will need a splitter to connect the audio cable from your laptop to the VGA Audio Input on the television. Never mind if you have speakers connected to your computer.

Press the Device button on the remote control or on the television front panel to display the Device Selection Menu. Select the device you want to view, in this case VGA. The only compatible resolution is 640X480 at a sync rate of 60 Hz.

Do not leave stationary or letter-box images on-screen for extended period of time to avoid uneven picture tube aging.

My television only puts out a pic in 480. The 720 and 1080 are not working. Getting sound no picture


No input on a WS-55511 is capable of 720p . Inputs COMP1 and COMP2 ONLY accept 480i/480p . Input DTV accepts 480i/p and 1080i . When using Input DTV with a component connection(YPbPr) and you get a green or no picture then you will need to navigate the menus and setup input DTV for YPbPr instead of RGB.

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!
