Mitsubishi WS 55805 nothing but blue screen and black square in middle


A full service manual is available online---I will presume you tried to unplug it for a while and then power back to see if will reset itself.

This set has three hidden menus---one is the OPTION menu--in that menu with the Mitsubishi remote you can do a hard reset of the entire set= sets all back to factory except convergence adjustments which are stored in another area--cures all kinds of oddball issues.

I can give you a link to the manual and the page numbers for the OPTION menu.

Note: the other two hidden menus are Convergence and adjustment--do not go into adjustment menu as one wrong move and poof!

Mitsubishi WD-57734 TV Powers on, Have sound, No Pic, Shuts down!


Hi,if you hear constant clicking or trying to turn on it could be your ballast.But if tv is between 1 yr -2 yrs maybe its time to replace the lamp.This will be the part number you need 915P061010 you can find it in discount-merchant to get the Philips lamps that normally last 2-4 yrs.God bless. The price will be around $129.99 you can replace it your self just put the part number 915P061010 on youtube and you'll see instructions to replace lamp.

I have a WS-55805. Was working great, then suddenly no picture, just audio. When I press the Menu button, I get the menu but I see three separate colors for each menu item. Could this be the lamp, or...


This TV does not have a single lamp but a set of CRT tubes.

If you get menu displayed on wrong clors or colors are not matching then it is either a bad CRT, a bad CRT high voltage power board, or sometimes a problem with convergence board and convergence ICs, however in this last case you usually get no picture and no sound .


You can get service manual from link below:

Mits ws-55805 No sound no Pictuer


FIRST CHECK CONNECTOR "DR" FOR PROPER CONNECTION, BETWEEN THE DEFL MINI PCB AND THE MAIN PCB. 2. CHECK C5A09 AND C5A50 BOTH 33 UFD 50 V OFF OF IC5A01 ON PCB-DEFL MINI. 3. CHECK FOR LEAKY IC5A03 PART # 270P704010 ON PCB-DEFL MINI 4. SUSPECT THE HIGH VOLTAGE BLOCK PART # 920P016010 IF STILL NO HELP PROBLEM CAN BE INTERMITTENT (TEMPERATURE RELATED) CAUSED BY IC7D04 PART # 275P245010 ON THE DOUBLER PCB THIS WOULD BE A THIN VERTICAL LINE IN CENTER, IF GUNS WERE ON.
