Just as I went to my theater room to verify the type of flashing LED I had (fast green blink, about 5 blinks per sec.), I can't believe I got the thing to power up.
I had tried on at least 4 occasions to reset my 7200 by unplugging and waiting even as long as 3 hours. Finally about a week ago, I just left it unplugged, and tonight upon finding this bulletin board, I figured I would try again since I was down there.
After plugging the power cord into the back and seeing the fast blinking green, I tried to press the power button, and nothing happened, so then I unplugged the power cord again, and noticed that the fast flashing green led still blinked a few times even after the power cord was disengaged. So, like double-dutch, I plugged the power back in real fast trying to keep with the rhythm of the fast blinking green, and quickly hit the power button, and to my surprise.. the unit made that "oh so marvelous "BING" (power-on) sound.
I wish I knew what caused my unit to go into this LOCK mode in the first place, (It's as if it never really shut down properly), and what I actually did to wake it back up.
I had exactly this problem. After plugging and unplugging it multiple times over several weeks (even plugging it in quickly after it was unplugged but with the green light still flashing as suggested here) all to no avail, it just started working on its own one day. It worked for a few weeks and then the problem re-appeared.
InFocus tech support recommended: 1. Check whether the lamp door is securely closed. 2. Check the color of the LED and the number of time it blinks. (For me, a very fast almost flickering flash) 3. Does the fan operate? (My fan would go on when plugged in) 4. Remove the lamp module, shake it gently and reseat the lamp module.
For me, these steps did not work. InFocus then recommended that I send it to ProjectorDoctor http://online.projectordoctor.com/, and it was diagnosed with a bad power supply. $395, but it is fully functional again. Good luck.........

Depends on how fast you're seeing. Cheap LED power supplies are what we call, "half wave". This means that they only work on half the AC cycle, and do blink 25 or 30 times per second (depending on where you are). If that's what you're seeing, it would be normal.
If they're blinking at some other rate, do you have them on a dimmer? Some dimmers don't get along well with LED power supplies, and blink at 1 to 10 per second.
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)

The front panel LEDs, refer to Figure 4-4, also assist in
determining the cause of a symptom. Figure 4-5 illustrates
normal LED operation. Figure 4-6 shows the
LEDs response when a problem is detected and indicates
the possible cause.

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/
Kindly provide the following for us to provide a direct and final solution to your problem
1. Does the blinking light changes from yellow to green or vice versa?
2. Is there a blinking red light?
3. How many blinks do you think it blinks?
Should you have any questions regarding the questions above, feel free to approach and ask us.
Good day and God Speed.
There are actually some certain meaning on the red light and green light showing different information to user. The summaries are: 1) Green On, Red Off = Printer Ready. 2) Green Fast-Flashing, Red Fast-Flashing = Printer warm up. 3) Green Fast-Flashing, Red Off = Printer off-line. 4) Green Slow-Flashing, Red Off = Processing Data. 5) Green Off, Red On = Cover Opened, Toner Empty or Developer Unit / Drum unit missing. 6) Green Off, Red Fast-Flashing = Paper Jam or waiting for jam reset. 7) Green Off, Red Slow-Flashing = Paper Empty or Paper tray is not inserted. 8) Green Off, Red Off = Printer power is off. 9) Green Very-Slow-Flashing, Red Off = Printer in sleep mode. 10) Green (any condition above), Red Slow-Flashing = Toner low or paper empty.
So what is your printer condition? Better know what is going on your printer so can solve the problem.
Ok, this is acting as if your MB is getting power but doing nothing with it. This very well could be a MB problem where something (unknown without looking at it) is fried. Just for grins, take the cmos battery out and let the pc sit for 1/2 to 1 hr before putting it back. If this does not work, I would contact HP for a replacement MB.
