    My receiver goes into protect mode when I turn the volume up. This is just a recent problem. I have checked the wiring for shorts and found none. I hooked another receiver to these speakers without any problem. The problem only exists at moderate to high volume.

    Same Mitsubishi M-VR1000 Receiver. Ran household stereo system for two years through this and now can't get out of protect mode. I have turned off all speakers and it still kicks into protect mode.

The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Your unit has an internal overload protection system to prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized service center must do this.] But, before you take it in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!

I heard a pop and smelled something that smelled like it was burning then the protect light came on then it shut off


Where there is a smell something burned---my suggestion is have a shop look at the unit and get a repair estimate---you can try that yourself but taking apart correctly is not always easy and there is a chance you might cause more problems---even if you find burnt part/s you will not likely know what got them.

turnit it off complety, unplug, check for speaker cable shorts and then power backup, if it does it still get a service person to look at it, one of the main output power transistors could be faultiy on one of channels amps

Mitsubishi Projection TV Model #VS-50603 will not turn on.


The TV is going into a "protect mode", the micro-processor has sensed a circuitry problem and has shut the set down so that no furhter damage can happen, you will need to have the TV serviced by a Mitsubishi tech. Good luck !

As soon as i turn on my STR-SE391 reciver the protection is on


It is unlikely that the pushing of buttons caused the problem. The protect flashing means that a problem was detected and the system has shutdown to prevent further damage. The most common cause of this is a failure of the output transistors. Plan on a parts cost between $20-$40 for this repair.

My Mitsubishi ws-55511 does not turn on. I push the power button and the tv turns on but turns off right after. I did the self diag. and the power light blinked twice paused and blinked twice again, then...


1.) 2-2 is short protection and usually means one of the two fuses that protect the convergence IC are bad.

2.) This model uses a Single convergence IC--A STK-393-110 THAT can be purchased for about 14 dollars plus shipping on ebay.

3.) If one of the fuses that protect it is blown the set detects no voltage present and shuts down instantly.

4.) I have photos of what the fuses that need to be checked look like; also there are several protect resistors around the chip that need to be looked at also--I have photos of them also.

5.) I also have step by step start to finish instructions for this repair for this model--It tells you how to do the repair and everything you will need to do it.

6.) If you want the photos and instructions give me a vote here and I will email them to you free.

7.) I do this here for free so if this has been helpful take a minute and give me a vote here.

Mitsubishi ws-55819


Code 22 indicates that your set is in shut down due to what is called Short Protect. The most likely cause is the Converge Ic's drawing too much current and opening one or 2 fuses. Normal repair cost varies by area and servicer. Expect 250 to 350 plus the service call. I normally do this on site.

Can the WS-55819 be reset through a reset button?


Code 22 is short protect. Recheck your work. Did you check and replace open fuses and/or Convergence IC's. The Conv. IC's normally open at least one fuse when they go out.
