Question about Zenith Z46Z70V 46" Rear Projection Television

Open Question

TV Shuts Off On It's Own

I have a 47" Zenith rear projection TV. Recently (about 2 weeks ago) the bulb blew out on it. Well before the bulb went out, the TV use to turn off momentarily, then come back on. We figured it was because the bulb was on it's last leg. Finally, it popped, fizzled and went out, and we replaced it. Now, the TV is still turning off, but this time it's turning off for longer periods of time. Before it use to only be a couple of seconds, now it's about 2-3 minutes. The light (indicating if it's on or off, usually green or red) turns completely off, like there is no power to the TV, a few minutes pass, and it turns back on by itself. I have no idea what to do next.

SOURCE: Need a red bulb for Zenith PVR5263RK rear projection tv

It sounds like your looking for a CRT (red) the part # is on the CRT and could be puchased through any Zenith (LG) distributer- usually around $300- $500. Google the part # when you get it and you may find a used Picture Tube (CRT)for cheaper.

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.

Bulbs keep blowing


You may be touching the bulb (ampule) and leaving a fingerprint on it which creats a hot spot and blows the bulbs up prematurely.
