Zenith IQC60H94W 60 inch rear projection turns off
Hello, my TV turns off while watching TV or playing games. When watching TV it happens every once in a while. Video games it happens all the time. High def TV all the time also. After a few years of dealing with this I have noticed that the brightness effects how often it happens, at least with video games.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.
The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.
Some time i may be the simple thing and as dumb as you may feel. If you have kids or other that push buttons. Check the menu setting make sure the color setting is turned up 3/4-1/2. yes some times we dont thinks it can be that simple. let us know what you find.
you can try to shut the tv off ,unplug the power to tv and anything that is powering the tv[pvr] .now plug in the power to the box first wait,30 seconds or so ,now plug in the tv wait,now turn the t.v. on,WAIT unless it starts smoking just wait.see what happens.
Sounds like a power problem to me. Possible shorting out inside the tv. If its old I would recommend discarding this tv. The price of repair costs are really high for TV's. You can probably upgrade to a flat panel for what the repair cost would cost you to repair this older tv.
Does it turn off and on as if you were pressing the power button? Or does it happen really fast? If its happening as if you were turning the tv off and then having to wait for it to come on again I would say its the power supply which is probably going to cost you hundreds in a repair shop. However you could possibly find a power supply for it on ebay buy searching for the model number and brand in the search area of ebay. Putting a power supply in a tv isn't really that hard, unless there is something in the way to get it in or out of tv. Usually it just involves unscrewing it from the chassis and unscrewing the hot wires and ground from the supply...then putting the new one in and screwing them back down.
Check the Vertical output IC and the Solder connections on the Vertical deflection yokes. Bad solder on the yoke plug connectors will cause the same symptom, and the Vertical IC may just need to be resoldered as thats fairly common with that model.
Everyone is right. The manuals for both projection TVs and video games specifically warn against playing video games on these sets. The result can be "pattern burn" from parts of the image that stay in one place for extended times. Once the face of a tube is burned by a bright image, it's visible all the time. If you intend to watch this TV, don't play games on it!
It's been a while since I faced one of these, but I believe the bezel around the screen pulls off to expose the screen mounting screws. As I recall it is held on by snap fasteners. It's also possible there is a snap-on trim strip between the screen bottom edge and the speaker grille. If that's the case, remove that to expose screws securing the bottom of the screen. Once they're out the screen swings up and off. Zenith used a couple of methods on different models.
