This is most often caused by a faulty lamp or faulty ballast. try resetting the tv by unplugging and leaving it unplugged for 5-10 minutes or so, plug it back in and check it.

Pix shuts off, green light starts flashing, pix comes back and shuts off again

If you have an issue where your picture turns off and the green power light starts flashing, you are most likely looking at a weak or old lamp. Do not be confused with a pix loss and a RED light flashing, as this can be caused by many things. The normal sequence of events for this fix is this:
1) TV turns on normally, plays for 1 to 3 minutes (may be more or less time)
2) Picture goes out and green power light begins flashing. It may flash for up to 2 minutes
3) green light turns on solid (stops flashing) and picture returns.
4) Picture goes out again and process repeats.

You may have been told that "if the lamp light isn't on, it isn't a bad lamp".
A weak lamp will cause the process above to occur. Other signs of a weak lamp:
The reflector in the lamp is very cloudy
You may see a "growth" or "bubble" on the vertical glass tube which is the lamp
You haven't replaced the lamp in quite some time or it is the original lamp from when you purchased the TV.

In cases like these, try a new lamp. Stick with an original Sony lamp, as there are many stories (both personally witnessed by me and also documented on the web) about problems with after market replacement lamps. And remember, lamps DO NOT have a shelf life; you can store them in a good environment (not too hot or cold!) for an indefinite period with no ill effects.

Green light flashing & no picture on Toshiba 40pw13p

There is problem with the lamp. It might need to be replaced. The lamp unit is on the bottom-left side of your TV. Loosen thumb screw (by hand) to take the the lamp unit door. Using a screwdriver, loosen two screws of the lamp unit and carefully pull the lamp unit out.
Put a new lamp in reverse order.

Blue screen with Green Star-burst image in center?

Here's something that might also be useful. 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.
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

No picture, won't turn off


the noise you hear after the melody would you describe it as like a buzz or a small chainsaw? If so you have a bad color wheel assembly. If the noise is intermittent than your issue could be the ballast that controls the lamp. If you've already changed the lamp the next step should be the ballast.

3 LEDs in the front blinking.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

PT-45LC12 wont power up

You have a bad lamp. The "clicking" sound you hear is the ballast (lamp power supply) attempting to start the lamp. The warning on Panasonics that comes up on screen does so when the life expectancy of the lamp is approaching. Otherwise your "clicking" sound and the red light on front are saying bad lamp. When you replace the lamp remeber to follow the instruction that Panasinc provides with the new lamp on restetting the lamp timer. This is usually done with the volume down on the TV and the PIP button on the remote.
