Re: t.v turns off while watching

Yes, it could be as simple as a cable inside coming from the auto link and 4 event timer. This needs to be redress from front control panel away from Blue CRT-yoke HV lead. For more info

Why won't my TV turn back on even manually??

total dead usually means the fuse---unplug the set for safety and remove back cover---follow power cord just inside and you will find the fuse in a snap in holder--check to see if bad.............if good let me know and I will try to assist you.

A friend gave me a Zenith LCD projection tv. model no E44W46LCD. She said that when she turned it on the screen was white then it turned itself off. when I got it home I plugged it in and when I hit the...

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Had a power outage while watching tv. Then 3 blinking lights.

This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

My tv screen is green

there is a code to reset the HDMI video, i think it is--hit Display on the remote, then sleep timer and video statice at the same time, then the number 2, then turn the tv off, after it shuts down all the way, turn it back on, should take care of it

Probably a solder issue. try soldering around the flyback, line coilsand vertical and yoke plugs. You can get a service manual for 10.99 emailed to you at the following link. they also offer free support to help with the diagnosis of your Set.
