Question about Zenith R57W46 57" Rear Projection Television

1 Answer

TV hesitates 15 seconds when it comes on. Will play until you turn off. Then will not come on until 10 to 15 minutes. We think it is on the main board. Do you have any suggestions?

    We changed the chip you said is breaking down. It seemed to work with the back off TV but when we put the back on it does not come back on after playing and getting hot. It takes about 5 minutes or so. We will replace the used part we put in the set and make sure the part is good. Do you have any other suggestions if that fails? Thanks, Elizabeth

Your horizontal output chip is begining to fail if you don't replace it eventually your set will not come on at all. You will push power and the indicator light will flash but your set wont power up.

    Is it any way you can send me some pictures of the Circuit board that you put the Output chip in. You can do this with your camera phone. Then send the pictures to willardbroughton@yahoo.com. We need to get to the bottom of this. Send as many close up pictures as you can.

    If you have a meter check the resistors and capacitors in the circuit something is allowing to much current to get to the chip.

What causes the TV to go on and off when first turned on, until it warms up for 5 to 10 minutes


Try turning the volume all the way down then power the TV an see how
long it takes to bring a screen up if you still hear a popping sound then you have a bad part with a bad connection most likey a lamp and wiring.
Call to have it serviced a must if so.

I have a Westinghouse LTV 32 in HDTV. Have had it for about two years. Last night when I turned it on I got no picture. I can play DVD's but still have no picture. Have tried everything I could think of....


I have a Westinghouse LTV32W6HD. Turned it on and there is no video for about 10 to 20 minutes. When the video comes on there is no sound until I go into the menu and select stereo and internal speaker. Don't know if this helps, but it works for me though my wife doesn't like it.

Extremely long warm up time 25 minutes. ok once it comes on.


Just a shot in the dark- I think your main projection lamp is going bad- If the set is more than a year or 2 old it can happen. Unfortunately they are a little expensive.
How is the brightness level after it warms up??

The solder joints on the vertical output IC have cracked. This is a very common problem on those sets.
