What do the mitsubishi codes 3 blinks then 4 blinks mean

If the LED's blink first red and then yellow, they are giving one of the 2-digit error codes shown in the last eight rows of the table, below. For example, 3 red blinks followed by 4 yellow blinks would represent error code "34."That means the lamp requires replacing.

On mitsubishi there can be 3 dots on the front and how/when the blink can be interpreted as codes. Do you have a POWER, a LAMP and a TEMP light on your mitsubishi?

Count the number of blinks...it is displaying the error code.
The number of blinks will repeat several times...count them.
Then contact Mitsubishi Tech support, they will tell you what the code means. For example, if the TV blinks 4, then 3 several times. The code is 43. Good Luck

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

It is a little misleading but means something in Horizontal or high voltage circuit (covers a lot of area inside the set) is bad.

Going to need a service manual, etc to try to track it down.

Entire chassis for this set can be removed====called a light box.

1blink-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

If it is 2,4 you have a problem in the vertical circuit and I would suggest you first look for any signs of glycol there.

Let me know if you need more information.

SD TECH

Mitsubishi self check: 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.

DO SELF CHECK IT HAS: WHEN SHUTS OFF PRESS AND HOLD BOTH THE MENU AND INPUT BUTTONS ON THE FRONT OF THE SET FOR AT LEAST 5 SECONDS AND RELEASE BOTH BUTTONS.

POWER LIGHT WILL BLINK TWO DIGIT ERROR CODE LIKE: 2 blinks, 2 blinks, a pause and repeat 4 more times.

let me know error code found and I will tell you what it means.

SD TECH

after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.
