Re: Red power button & "lamp" indicator blinks

Having similar issue with my PT-44LCX65. Lamp blew and replaced it (last month), never figured out how to reset timer. Now red indicator light blinks once every 5 seconds and after about 4 minutes TV goes black.... Any ideas?

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.

The lamp light is blinking once every 5 seconds. The manual says that " Lamp will not light or light is abnormal"


Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.

You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.

Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.

The user's manual has a description of what the Blinking LED indicators mean.

TV was working fine when we went to bed Monday (August 30) night. Got up the next morning and turned it on. It appeared it was going to come on, the green light flashed and then the lamp indicator light...

1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. 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. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6.

Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).

Panason PT-50LC13 TV won't come on, light blinks green then red

Ballast failure is more that likley the problem. Is the lamp light blinking,...once every 5 seconds? Discontinued part and can only be purchased used or rebuilt. Rebuilt units are available, check Ebay. Have a service type person confirm problem before throwing good money after bad!

Had blue screen, now no picture and red light

Press the menu and the device/input buttond on the det both in together and hold in for 5 seconds to see if the led will blink a two digit code such as 3 blinks slight pause then 4 blinks. I would almost bet that you have a 34 code come up. But respond to this same post and let me know which two digit blink code came up, and I will assist you with whats wrong with your DLP.

Turn on and Power and Lamp Lights blink.

Just because it doesn't look broken doesn't mean it hasn't failed.
Is the TV over 2 years old?
If so, buy just the bulb (not the whole lamp assy) from us at, install it yourself and save about 75% of what Mitsubishi charges.

Hitachi 55VG825 rear proj television blinking light and screen doesn't light up

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
