I have tried to turn my television on and the status light blinks for about a minute, you can hear the TV try to start up and then the whole system shuts down without anything actually powering up. Also...


Unplug the tv for about a minute - plug it in and press the reset button on the front of the tv - hold it until the light blinks. The set should come on in a minute of two - if not try the same routine again.

I replaced the lamp however the green light blinks for a minute then the lamp light comes back on and the tv can't be turned on. WD-Y57 model


with that model after the tv shuts off pres the "menu" and "device" button on the front panel buttons together for about 8 seconds and then the power led will blink green. it will blink a certain number of times then pause and blink a different number of times this will be the error code for the fail that the tv thinks it is having. for example it may blink green 6 times then pause and blink 1 more time that would be code 61 check the code and repost and i will tell you the next course of action good luck

We have a samsung HLN 5065 w projection tv.


Hi,if you hear clicking it could be the board that powers the lamp its called the ballast Was the fan
running ok? You can clean it w an air pressure
can. If you heard clicking or like wanting to turn on the problem could be with the board that powers the lamp.The board it's called the ballast.If its not able
to provide the power to the lamp it will not turn it on
and the red light will blink.Also pay attention to sounds off buzzing which could indicate a color wheel issue.

Mitsubishi WS-55511 Problem TV out - Getting only continously blinking green light on the front-panel


I had the same problem with the blinking light on the front of the TV and it would not power up. I read all the problems everyone was having and thought I was going to face a huge repair bill. The service guy came out, pulled off the front panel where the speakers are and disconnected the circuit for the front display panel. 3 1/2 minutes in my house, $90 service call. Apparently, when you give the TV too many commands at once, it's safety feature is to"shut down and lock up". He mentioned also that sometimes when these sets get to be about 4-5 years old, the wires in front can "leak" causing a shortage and then locking up the TV. I keep the circuit unplugged and operate the TV solely by the remote. Give it a try, what can it hurt!! Hope this helps.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Blue screen and shut off by self


You will need to reset the Netcommand and tuner settings in the set. The little indented button in the front of the set needs to be pushed in (when the set is off). The front light will blink for about a minute or minute and a half. Then, reprogram the Netcommand settings. This should solve your problem. If you need more information, then, reply to this post and I will respond.

The color wheel is the most common problem when it comes to noise from DLP's. To determine if it is a color wheel or fan: Turn on the set. When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is bad. If the noise goes away after one to one and a half minutes after the set was shut off, then one of the fans are making the noise.
