My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


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.

Good Day, I have 3 sony ex3 projectors - 2 of which have an intermittent lamp/cover error where the lamp/cover led blinks and the machine does not light. The problem is still there even after i press...


The small lamp cover dimple that is supposed to activate the protection switch doesnt reach the switch if the cover is slightly curved due to age and heating.
So I put a small dob of silastic on the dimple of the lamp cover and let it set for 24 hours. Then I put the cover back into the unit and all is OK.

In your testing, make sure you are pressing the switch down manually before you power up the unit.
Then the error message is not likely to be a cover error message.
If you still get the error then I would check the integrity of the switch mechanically and electrically. Check that the connector from the switch to the pcb is OK.

Replace the 2 bulbs. Unit powered up correctly and turned on like normal. Then Lamp1 and Lamp 2 indicator lights blinked (Indicating Start UP). After some period of time, it switched to Red 6 times blink...


1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.
i have nothing on 6 ligths go ahead reconect and check for proper count. hope this information helps.
Best of Luck.

Ray.

KDF-70XBR950 70 in. Rear Projection HDTV Television My TV took a power surge and I?m getting the 3 blinking lights, I read online that it?s probably my g3 board. I check the lamp and the cover but...


Hi,
3 times red standby blinking light indicates Lamp Cover is not attached securely or Lamp has not been fixed properly inside tv. Make sure lamp and lamp cover are securely attached in tv.
I do not think G3 board is bad because 3 times blinking error is related with lamp cover that engages micro switch inside tv.
Let me know your findings to provide you more helpful info.
You can download service manual from This Site for little fee.
Thanks.

Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. 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 4.

Red Light Flashes twice KDF-E50A10


Are you putting the lamp cover back in place before trying to turn the set on? The 2 blink error is a temperature error you might want to check the thermal sensor, is your lamp door warped?

Sony KV36FS100 - Has sound but no picture and stand by light blinks when TV is off


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://homenol.blogspot.com/
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
