Check the solder connections on the audio output ICs and also around the external sound connections often the ground trace will develope a solder crack and will cause a loss of sound.

My ws-55311 shows blue screen on all inputs except the DTV input


This set has 3 hidden menus accessed with a different 4 digit number code----You need the Mitsubishi remote to enter.

One of them is the Option menu which will allow a hard reset of the TV back to factory original---98% of the time it will restore all inputs--cures all sorts of odd problems.

If you have that remote and want to try it let me know for sure the model number and I will give you a link to the instructions for doing it.

Is it possible to use the rgb input on the sd-643hd5 as a computer monitor input? My laptop has a female 15 pin video out which seems compatible with the tv's input except that they are both female...


O don't see why not. They are both female by default, as we don't want VGA pins poking out of the rear of our laptops to catch on stuff.
Don't forget to tell the laptop to switch to external screen.
Hope this helps.

RCA HD52LP: Composite video inputs don't work


RCA Authorized service tech looked at it. He determined that the DM Module need to be replaced. The part alone costs $550 + labor. Since the HDMI and component video inputs seem to work, he suggested buying a VCR DVD combo with HDMI output which would be far less than repairing the tv itself. I'n researching the possibility of purchasing the part myself.

When i have my cable tv hooked directly from the wall into the Ant A input on the tv i will loose picture and sound for a little while for no apparent reason. It started about 6 months ago and i learned...


check the tv setup menu for rf input mode [choices will be 'air', cable' and cable hrc'] usuallu when this is set incorrectly, the upper channels will be most affeced, and in most cases the video quality suffers- however, if the set is otherwise functioning properly, it is possible that this setting is not set for the signal you cable provider is sending. in hrc mode, some channels are shifted a half megahertz. good luck

Child Lock is on and I am second owner of tv with no code


This function will block out the picture and sound of the selected channel or video input.
It can also be used to keep the TV from being viewed for a scheduled time period that you set.
The code to enter the Locks feature is a four digit secret code number. The factory preset code is 0000.
Use the number buttons to select access code.

Use CURSOR G or H to highlight function and then press the SELECT button.
To change the access code number, select Change Access Code. Enter a new four digit key number you prefer.
Select CHANGE ACCESS CODE to change factory preset code (0000) to your preference.
When ENGAGE LOCK is selected, SET CHANNEL LOCK, SET INPUT LOCK, and SET FRONT PANEL LOCK can be set individually.
When SET CHANNEL LOCK is turned on, the picture and sound for the chosen channel will be blocked out.
When SET INPUT LOCK is turned on, the picture and sound for all video inputs and the picture and sound for channels 3, 4 will be
blocked out.
When FRONT PANEL LOCK is turned on, all buttons on the Front Panel will be deactivated, except the Power button.
When TV TIME LOCK is turned on (r TIME LOCK) you can set the BEGIN and END times (CURSOR E) and the TV
cannot be viewed during that time period (Set clock first). Use CURSOR G or H to highlight ONCE (TV will time out one time
only), DAILY (TV will time out every day), WEEKLY - SUN~WEEKLY - MON (TV will time out one time a week) or OFF (to disable
this function).
When MOVIE RATINGS is selected, you can block various types of movies and video tapes based on motion picture ratings. Picturein-
Picture will also be blocked automatically (see page 45).
When TV RATINGS is selected, various types of television programming based on a parental guide ratings will be blocked.
Picture-in-Picture will also be blocked automatically
If you forget your secret code, use the factory code 7777 to erase your key number. This will reset the secret code number back to the
factory preset 0000.
Press EXIT to quit the menu.

Satellite input


Most tv setups require that you change the input source to gain the ability to watch the proper peripheral e.g. if satellite is connected on video one and the dvd is connected to the tv on another input such as video 2.

If the satellite runs into the dvd unit and from there the dvd is connected to tv you may have to power off or on the dvd player to resolve conflict.

Another problem may be the resolution setting if your tv is Hi Def. Set the tv and receiver to the resolution e.g. 1080i.

You can also changed the way the satellite is connected to the tv possibly if you have other inputs.

Check the channel also, if the unit is connected with coax it would more than likely need to be on ch 3 or 4 if you are at the satellite receiver box location. If you are at a stand alone tv off of a dual tuner you may need to search the channels for the right source both air(analog) and cable(digital).
Hope this helps you out. If I can be of more assistance let me know.
