Audio but only black screen for video on WS65807


First, the set has a hard reset but it will NOT affect convergence which is stored in a separate area of the set.

Model indicated has 3 hidden menus---all accessed with the Original remote and a 4 digit code.

At your own risk:

This is a V17 chassis that was used in 8 models.

It has 3 hidden tech menus: With set on:

Option menu is 8270 enter---The Option menu reset will return all settings to factory and also will clear any glitches out of the way--it as stated can cause Convergence not to be affected.

Circuit adjust menu: (stay out as one wrong move and fatal things can happen is : 8257 enter.

Convergence adjust menu: (better than customer and SAVES adjustments made in to the DCU or digital convergence unit in the set.

I STRONGLY SUGGEST YOU TRY THE OPTION MENU FIRST, IF NEED DETAILED INSTRUCTIONS I CAN LOCATE THEM FOR STEP BY STEP OF THAT.

SEE IF IT CLEARS THE MAIN ISSUES UP FIRST---IF YOU TRIED TO ADJUST CONVERGENCE IT MAY NOW BE MESSED UP BUT UNLESS YOU GET THE SET BACK TO WORKING SOMEWHAT NORMAL NOTHING TO WORRY ABOUT.

keep in mind I do this here for free and have worked on hundreds of these Mitsubishi sets.

NO PICTURE!!!! Please HELP! I am going to kill my husband for bringing this TV home!


If the model number is correct and all you can get is the menu or on screen displays to work the set may need to be reset--not on the front or in the menu.

The set has 3 hidden menus: adjustment (keep out), tech convergence, and the OPTION menu.

Option menu enables a hard reset to factory of all settings except convergence and is designed to fix odd issues.

You need the Mitsubishi remote and a 4 digit code (model specific).

If you have the remote and want to try it let me know what the actual model number is and I will give you a link to the service manual which tells how to do it correctly.

I would like know how to reset settings for the colour brightness sharpness etc (factory settings)


Usually factory defaults are set to the middle settings in your menu structure. If you have values then it would be the middle of the value.
Is there any certain reason why you wish to go into the service menus?

Color


see if there is a "default" option, if not set everything back to the middle, if the colors are still off you sure its not the convergence?
most big screens allow you to change "color temperature" it's like a default adjustment for 3 different brightness levels.... ie...COOL, WARM picture will show obvious changes in brightness

No sound


Look in the menus for a setting to turn the speakers on and off. Make sure there isn't a switch on the back to turn off the internal speakers.

No sound or picture


Try 2 things:
1. If you have a cable box with the yellow/white/red outputs, use a compatible cord to run the 3 to another input on your TV (ie input 1 vs cable). and/or
2. Do a Factory reset. Hold the "menu" button on your TV then on your remote hit "menu" then "8" then "select" and go to "factory reset". You may have to unplug the TV as it may freeze on "factory reset". Replug it then try it out.

Hope it works.

Just bought a PANASONIC PT-47WX53G On ebay for what I thought was a steal. It was explained that somehow someone got into the service menu and messed something up with the convergence on the green gun....


You can try restoring to factory defaults, and you can try the manual convergence option. If the manual convergence fails to reset (as in, the crosshairs physically will not move), then the convergence board is bad, and will need to be replaced or repaired (if you are a good circuit solderer).

go to you menu settings and be sure speakers are turned on and are not set to external,if this does'nt fix remove your dish input to see if you have noise comming through with no picture only snow, if yes the dish is the problem.
