    This is interesting since I just had a technician to the house and he just replaced the bulb to try to fix my problem with the tv going off.
    This is the second bulb that he put in.
    The first bulb was the wrong one or defective because the tv picture was very dark.
    when he put the new bulb in at least i got my good picture back but i still have issue with tv turning off by itself at random.

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.

I changed the bulb on my Zenith Z44SZ80 and the TV picture is really dark and not bright like it used to be. The old bulb was 100w and the new one is 120w. I tried adjusting the brightness and contrast...


curthansen,

You should revisit the lamp by removing it and checking for any obstruction in the light path. When satistied that nothing is blocking the light path and if you still have low light levels I would contact the vendor and try to exchange your lamp for a new one. If the unit is still dim after installing a new, 2nd lamp, I would replace the ballast board assembly. I have a tip at http://www.fixya.com/support/r4977572-when_change_ballast_in_dlp_tv which explains the problem, how to fix it and where to get the parts at the best price.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank You.

How to reset the DLP TV Lamp Counter


Press and HOLD the ENTER (or OK) button on the TV
Press and HOLD the MUTE button on the REMOTE
(hold both until the LAMP LIFE HOURS appears on the screen)

Tv keeps turning off


Almost certainly the lamp. You should be able to take the lamp out and get a part # off of it. They are easily obtained and easily replaced.

Zenith dlp projection t.v. model#z52sz80 t.v. turns off randomly


This solution is for the zenith 56" DLP. Unplug the tv, either from the wall socket or the TV. While the TV is unplugged hold the power button on the TV for 40 seconds. This lets the excessive power drain from the TV. If this does not work call 1-800-243-0000. This is the number for their help line. This is the fix the tech gave me and it worked right away. Hope this helps and have a great day.
