These 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://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Testimonial: "Thank you for the reply. The set will not power up at all so checking for fault codes is impossible. When the problem occurred the set was off and I could hear the main relay clicking, then I noticed the power lamp flashing, the only way I could stop the clicking and flashing was to unplug the power cord, after plugging the set back in, all I have now is the set not powering up and I just have the continuous flashing power lamp. The main board faulty? That sucks, looks pretty easy to replace though. Mark"

It is possible that you have a bad power supply, or the TV has been hit by a small power surge and if you unplug the set from the wall for 40Min., it will rest back to normal.

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.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

Green Blinking light on Mitsubishi Unisen lt 40164, tv wont turn on?


Hi Since that did not work, The next thing is you have to take the back off the TV and find the main power board. On that board there will be some bad capacitors. Look for bulged or leaking CAP(s).
Replace them with same capacitors types. If you're not tech. savy Go to TV repairman. Good luck.

TV turned off by itself one day. I pressed reset, timer light blinked green for a minute, then I pressed power and it sounded like it wanted to boot up, but nothing happened and the status light turn


Two thoughts:

First is this is a DLP set and the lamp may have failed

Second is it should have the self check which reads error codes---most of these sets that is the same:

" After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
(then release both)

The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
This is for a earlier Mitsubishi DLP but should be the same as your set as Mitsubishi rarely changes things like this.
If you get the lamp abnormal it is likely your problem.

On a mitsubishi tv (LT-46149) the manual intructs us to wait exactly one minute for the LED green light to stop flashing and then its alright to turn on the tv, the problem is that the light wont stop...

Call MITS, and try to get a tech to assist. Green timer flashing is "waiting for CPU to boot". Normally 70 seconds after plug-in. If doesn't stop, then not booting, and you won't be able to turn on. It only boots after being unplugged.
