No you have drained the cooling liguid and now the set will not work untill it is replaced. First off there is no picture tube in these tv's, I guess your wanting to replace the bulb, or the three color tubes.

Because of the fact that the TV is a big screen, labor might be around $70-$150, depending on who you hire to perform the repairs. AND, this is also assuming that the repair does not require any replacement parts.

I would recommend that you shop around to find a repair shop that has the lowest rates (but be sure they also have a good reputation). Also ask if the shop gives free repair estimates and if they will do house calls so you won't have to lug the thing to a repair shop.

A new big screen will cost you more money than getting your broken set repaired (unless the problem with your broken set is REALLY big).

But, consider what you've gotten out of your set. If the set is certainly old (like, say 10 or so years), then it might be a good time to consider replacing rather than repairing. A bigscreen that's old enough will exhibit certain problems related to age, such as old coolant for the CRTs and the projection lenses (which can be replaced relatively inexpensively), old high voltage components such as the flyback transformer (which do fail over time from constant use since the internal windings have insultation that will break down and allow the windings to short themselves after enough hours of use), and/or old electrolytic capacitors (which were a really big problem with Mitsubishi equipment from the 1990s since they had big problems with leaking). If you are considering replacing, donate the set to any repair shop that's willing to take it in. They will either refurbish it themselves and resell it or, more likely, they will strip it for parts and dispose of what they can't use.
Otherwise, it may be best to go ahead and find someone to fix your current set. Just go to Welcome to Mitsubishi Parts and plug in your model number. I will assume you're talking about CRT RPTV since you mentioned 55" in addition to bulb(s). Anyway, I just noticed the Mits website only returned 6 items when I plugged in my WS-55511 so you will probably have to call 1-800-553-7278

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.

Relay Connector on Mitsubishi TV


IF IT IS A WS-55511 what you are reading is with the speaker grill removed--there will be one or two sets of wires coming from the front keyboard--before you remove the entire screen assembly you need to follow them to the right and unplug both plugs.

The screen assembly will have about 5 screws at the bottom edge--with both plugs free and the screws removed you pull up and lift the screen about 4 inches and pull it off--if you have questions ask before you attempt to remove the screen unit--tell me also why you want to remove it.

Ws-55511 replaced all 7 caps in the dm, still wont power on


I have seen this only 2 times----you may be able to unsolder and remove the reset micro switch---you have to remove the whole screen to get at it---the micro switch board may not be available---the switches can be tested with a ohmmeter set to high end and of course should not have a reading across them--I bet the reset switch is bad--you can remove it and put the keyboard back---most of the Mitsubishi sets use the same type of switches--Only other thing is leave the keyboard disconnected and just use the remote.

Glad you found the problem.

I had a power outage and now the tv will not power on. This is for a 55" Mitsubishi WS-55511. no green blinking lights.


Hi,

You may have a blown fuse. Unplug the TV and remove the back. Look for a small fuse near where the power cord goes in.
If it is blown that may be the problem.
Use a magnifying glass to read the AMP rating.
replace the fuse and plug it in. If the fuse blows again you need expert repair services.

If the fuse doesn't blow then try to turn it on.
If it turns on then check the operation of the TV.

If the fuse blows again or the TV won't work correctly then you need expert repair service to fix your TV.

You may be able to have your household insurance pay if it is damaged by lightening or a power surge.

WS-55511 55in volume turns up by itself & can't switch devices


The remote is not the problem. The switch for volume up on the control panel has become leaky. Very common problem for this generation Mitsubishi. If you don't mind not having the control panel working you can disconnect it and the set will work just fine with the remote. To disconnect the control panel pull the speaker grill, it just snaps off, and remove the front access panel. Once that is done you'll see a cable going to the switches just disconnect it.

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!

Will not power on. Please Help!!


Error code 12 means normal operation. On these models we have found that a switch is sticking on the control panel not allowing the set to turn on. Disconnect the control panel. You will be able to use the remote on it. To find the plugs for the control panel: Remove the speaker grill and front panel, then follow the wire to the connection. Remember to unplug the set before putting your hands inside of it. Tell me how it went. Lead Tech
