What does a blinking orange light on 65" Mitsubishi dlp rear projection TV mean?


Self Diagnostics

The V18 Chassis features Self Diagnostics to aid in troubleshooting problems that may cause the set to

automatically turn off or "shut down." The "Timer/Power ON LED" provides an indication of the sets operation,

and the possible cause of a malfunction.

1. Initial Control Circuitry Check

Immediately after the TV is connected to an AC power source:

• The LED flashes three times ... indicating the Microprocessor has initialized and is functioning

properly.

• If the LED does not flash ... the Microprocessor is NOT functioning.

2. Error Code Operational Check

To activate the Error Code Mode, while the set is OFF, press the front panel "INPUT" and "MENU" buttons

at the same time and hold for 5 seconds. The LED will flash denoting a two digit Error Code.

Note: The Front Panel buttons must be used, NOT those on the Remote Control.

• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: For Error Code is "24", the LED will flash 2 times, pause, and then flash 4 times.

3. Error Codes

The Error Code designations indicating a malfunction, or no malfunction, are listed below:

"12" ... indicates no error has occurred.

"21" ... X-Ray Protect circuit.

"22" ... Short Protect circuit.

"23" ... Horizontal Deflection failure.

"24" ... Vertical Deflection failure.

Shuts off and on while trying to watch, the power light flashes 30 times when off then the tv comes back on again


Power supply trouble. The TV keeps trying to start then operates for 2 seconds and shuts down. The cycle keeps repeating until eventually the TV will not start at all.

Power surge from storm. Power light turns on for 2-3 seconds and goes off. Previously had a power supply replaced 3 yrs ago. tv is approx 12-15 yrs old.


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

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


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

before you rate this information or if you have questions let me know what you find.

What are the error codes for a Panasonic PT-47WX 42 TV


Hi,
3 times LED blinks in Panasonic PT-47WX42 shows problem with convergence out chips failure as this tv has two big black ICs STK392-110 as convergence output, replace them to fix tv problem.
Click Part Store to see an image of required chip and price info.
Local tv tech is recommended if you have no experience of working in tv circuit boards.

Power shuts off 1 second after tv is turned on


Good Day,

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 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. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC).

2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. 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.

I hope this was helpful, BIG IRISH.

The tv sound works all the time when turned on but occasionally the video either does not come on or goes of while watching it.


It is usually a vertical deflection circuit problem. Here's the basic troubleshooting:

  1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
  2. Press MENU button. If a small horizontal line appears at the center of the screen, you have lost vertical sweep on your TV. The protection circuit shuts down the picture to protect the tubes from burning a line across them. The intermittent problem may indicate a loose solder. Try resoldering the vertical output IC. The IC along with the B+ feed resistor back in the sweep power supply is most probably bad or has a loose solder.
  3. Press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
  4. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "24", the LED will flash 2 times, pauses, then flashes 4 times. The error code is repeated a total of 5 times. Error 24 indicates a vertical deflection circuit failure.
Please let me know the code you'll and I'll tell you where the problem lies and how to fix it.

Here's the basic troubleshooting:

  1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
  2. Disconnect ALL devices from the TV.
  3. Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
  4. Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
  5. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
  6. If it still shuts down, press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
  7. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.
Please let me know the code you got and I'll tell where the problem lies and how to fix it.

I believe 4 blinks is fan error. You can take back off and watch fans in particular the fan for the lamp (this one goes out the most) The TV has a sensor so it knows if the fan turns.You can take a pencil and use it to spin fan sometimes that will jump start it (not a permanent fix just a test). You can try cleaning dust off fan and replugging the connector on the wires coming from fan.Might fix it if not fan will need replacement.

Power LED blinks red


it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
