Protect My Mitsubishi M-VR1000 turns on then breifly flashs "PROTECT" then immediately shut down. I can find no fuse or reset externally to change or push. So, what do I do and does anyone have a user manaul?

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!

Mitsubishi WS48413 makes a clicking sound and turns off right away

this is a V22 chassis circa 2003/2004
you could have an issue in 1 or multiple circuits. it is key if you can determine any error code. Error code is determined by blinking LEDs on front of unit after it shuts down. It will blink a certain number of times, pause then blink another certain number of times. It repeats this cycle 5 times.
12...no fault detected
21...X-Ray protect
22...short circuit protect

23...deflection circuit
Continuous flash...most likely DM circuit.

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.

When I power up thr TV it immediately poers back down BEFORE the screen shows a 'picture'.

I hate to be the bearer of bad news, but it sounds like the "over voltage protect circuit" is doing its job. There is a 130 volt regulator circuit in the power supply that limits the high voltage to around 30,000 volts at the second anode of the picture tube which limits the x-rays emitted from the crt. If the regulator fails, there is this over voltage protect circuit, which immediately shuts down the power supply and the TV. Turning off the TV resets the protect circuit. Turning the set back on, will cause the protect circuit to engage again. If you're competent in electronics, it is possible to aquire the parts and do a successful repair for under $20.00 in parts, but beware, there are a lot of dishonest people out there ready to take your money. Hope this helps! Dano

Protect flashes. I reset as manual instructed. I

Don't forget to disconnect your sources also(dvd,satellite,vcr,cd player,etc) they could have a short in any of them causing receiver to go into protect,If still flashing "protect" your Sony could have an internal short of it's own, or caused by an external short previously mentioned. Good luck !

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.

Projection TV keeps shutting off

Good Day, checho3435;

Try this to help to narrow it down:

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. Good Day, big IRISH.
