Tv does not power on

A button may be stuck down, this is what happened to my TV when a button was stuck.

It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



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: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

I happened the same problem and the solution must change the power pack

A constant flashing light near the main power switch normally indicates a problem with your device's electronics, ranging from image board errors to power supply failures.
It is best to contact the manufacturer's customer support line to get the appropriate trouble codes and best advice.
Hope this helps.

Replace the Lamp P/N 915PO20010 if it has never been replaced.
Mats Electronics has them for $99.00 1-800-628-1118

Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.

If you replace the lamp, but get the same problem, check the inverter board.

If you're not sure where the inverter board is, then you may need to contact a pro for your safety.

Good luck and have a good evening!

Most likely the lamp is burnt out (indicator goes to constant red status). Replace lamp (get lamp P/N from User Manual for replacement), clean any dirt around lamp, fan, and rear filter. Do NOT get any fingerprints on new lamp.

The control systems on power mobility equipment have a "prevent" circuit that immobilizes the equipment while it is plugged into a charger, so folks won't take off with it plugged into the wall outlet. When you turn it on when plugged into a charger, the display will flash constantly, or sweep constantly, depending on the manufacturer. This is normal. Your off-board charger should have a red light to indicate power to the charger, and another light for the charge status. Yellowish means it is charging, when it turns green, you are fully charged. If the status light is green all the time, that is an indication that the charger is not functioning properly, or that the batteries are below a chargeable state. Check charger output, which should be 26-28 volts dc, and each battery should show at least a 12 volt reading, but around 13.5 volts with a full charge. If one or both of the batteries drops below 12 volts after a short period of time, it's time for a fresh pair. Fully charge new ones before using the chair.

The 18 code does not exist. To read the code press device/input button and menu button at the same time on the tv. count the LED flashes 1st digit short pause 2nd digit long pause, repeats.

The red status lamp indicates there is no communication between the format board and the DMD board (light engine). The most common problem for this is capacitors on the Format board that require hours of labor and possibly sending the entire electronics package to Mitsubishi if the caps don't do the trick. Expect a very large bill, contact you local Mitsubishi Authorized repair facility about this, DO NOT take a chance on your corner repair shop to know how to accomplish this.

A steady red light: there is a short on the DVI cable from FMT to DMD disconnected
