Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

My T.V. Will power on for a couple seconds then immediately turn off! Please help!


Hi,
Unplug the unit from the outlet for at least 1 hour and check if the symptoms persists. If yes, check if the unit can give an error code by following the steps below.
- Power on the unit and wait until the initialization takes place.
- Press the front panel "Input" and "Menu" buttons at the same time and hold it for 5 seconds, it will activate the error code mode. LED flashes a two digit error code. Example, if the error code is "22" the LED will flashes two times pause and then flashes two times and will repeat the error code for 5 times.
"12" means no error has occured.
Please let me know what will be the result to assist you further.
Regards,jimvincentvillanueva@yahoo.com

Takes to long for unit to come on, when pressing power on remote, green light comes on, but it takes over an hour for the picture to come on.


could be a lamp problem, turn the set off, watch the front led light next to LAMP, count how many flashes in sequence, eg. 2 flashes indicate lamp problem, 3 flashes internal overheat problem. if a orange light flashes next to POWER indicator you have a power malfunction.

7.1.4 The method of power-on (for service)
When removes the Front Grille, remove the
connectors from POWER SW Assy, FRONT INPUT
Assy and FRONT LED Assy and remove the Grille.
This set is not turned on the power in the state that
removed the connectors.
At this time, connect a connector that connected to
the POWER SW Assy to the SHORT Assy, and can
turn the MAIN POWER SW to ON.
Be careful there is a case to be turned on the power
in the state that front side of this set opens.
In addition, the front input and front key do not work
because each Assy does not connect it, but the
remote control unit works in the same way normally.
There is a Factory Key on the FRONT LED Assy.
When enter the Factory mode, transfer a code with
the remote control unit or connect the FRONT LED
Assy. (Turn the Main Power SW to OFF when
connects it.)

Mitsubishi WS-65613 tv green power light keeps blinking tv will not turn on


Unplug the unit for 5 minutes then plug it again. Turn it on. If it does not power up, press the SYSTEM RESET button on the front panel with a pointed object such as the point of a pencil or end tip of a paper clip. The green LED light will flash quickly for about a minute then stops. You may turn on the TV then. The changes you made most recently, before using
SYSTEM RESET, may be lost. Changes you made previously, however, are not lost.

Green light on front rapidly blinks after power outage. No picture, or can't turn on


This unit, when first plugged in or after power interuption takes 70 to 90 seconds for the digital module to boot up. During the time the LED blinks green and the set will not respond to anything. After the appropriate amount of time the blinking should stop and the set should operate normally. If the blinking never stops then you have to have the Digital Module repaired.

Tv mitsubishi ws-65315 doesnt turn on,only green light


Good Day, cutito35; 1. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds. 2. (Power LED may be on after plug in) check for no less than 4.4 volts DC at pin 3 of PC9A21 on the Power PCB, if low or missing replace PC9A21 part # 268P058020. 2.This model is also 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 open fuses F9A04 and F9A05 part # 283P144080 on the +24 and -24 volt lines. If the fuses are open the convergence output circuit would be suspect. 2. Shutdown at power with self diagnosis error 2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C52 part # 441D009020 on the Signal PCB. Good Luck, big IRISH.
