20 Most Recent Mitsubishi WS-55311 55" Rear Projection Television Questions & Answers


If model number is correct WS55311 this set has a hidden menu (actually 3 of them) and one is the "Option" menu where you can do a hard reset of the set; it buts everything back to factory default.

It is done with a 4 digit code (I know depending on what model number is) and the original Mitsubishi remote has to be used for this.

Confirm actual model number and I will give that code to you.

When power light goes out on front of set press both the menu and input (device) buttons at the same time for at least 5 seconds and release both buttons.

The power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and then repeat it several times.

Let me know what error code you find and I will tell you what it means.

If this told you something you did not know rate this solution as very helpful as I do this here for free.

When it shuts down have you tried accessing the self diagnosis feature to retreve the error code?If so whats the blink code your getting?

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.

2,4 is one of 5 error codes and means:

2blink-then 4 blink---------vertical circuit problem

The set may have a loss of sweep or even Glycol may have leaked from the picture tube above it onto the board in that area.

Vertical circuit is on middle board at front right edge.

Please listen and try this:

When the power light comes on and goes off, on the front of the set press BOTH the Menu and Input (Device) buttons at the SAME time and HOLD them both for at least five seconds and then release both.

The power light will blink a two digit error code and will repeat it about 5 times. To get it to repeat you would have to unplug the set and turn it on again etc.

The most common error is 2 blinks, pause, 2 blinks.

Let me know what error code you find and I will direct you as to what it means and what may have to be done.

This is a V20 chassis and if it shuts down it should trigger an error; note if no error the power light should blink 1, 2 pause and repeat it several times---this is no error found.

I would unplug the set for a few minutes (this clears the error buffer) and turn on again and wait for failure; you must push menu and input and hold for at least 5 seconds and let both go.

IF no error code this is a model made around 2002 (date will be on back of set) and it must display some error code.

If you find none I can suggest looking for any signs of Glycol leaks inside the set. If you need to know what to look for let me know and I will tell you.

Again: All models after 2000 (and some before) have the error buffer.

Let me know if you have questions.

Hi.

If there is sound but no picture it means that the three CRT picture tubes are not receiving power.

The first part to test is the power supply (PSU). The PSU supplies power in different DC voltage to the different circuits of the TV. The higher DC voltage line goes to flyback and then to CRT. Testing is done reading the VDC line to flyback.

Here the part: Power V20/V20B

If the PSU is OK the flyback transformer is usually responsible. This part is tested reading voltage in (if it is OK part is usually bad) and testing solder joints and components. Here the part:
Transformer -Fb

The contacts and solder joint in the individual CRT housing must also be tested checking if there is continuity between contacts with CRT and solder joints on the other side. It is unlikely that three CRT housing go bad at the same time. This test in more of a routine check.

If the parts mentioned above are OK the problem is the digital controller board.

Try first disconnecting power for five minutes. If that does not help the TV must be disassembled to test parts mentioned above and to replace faulty part.

Here all parts for your TV.

Regards.
