Question about Zenith C32V37 32" TV

2 Answers

Screen goes green with white vertical lines

After about 40 minutes of operation the screen goes green in color with white vertical lines across the entire screen. By shutting the TV off for about 3 - 4 hours the picture will be fine for about another 40 minutes or so and then it does it again. What do you suspect the nature of the problem is and what parts would be needed to repair it? Thanks, Bob

    C32V37 32" TV - The degauss solution didn't help. What I would like to get now is a schematic for this TV, preferably the schematic only without having to get the entire service manual. Where on I get the schematic? Thanks

Your problem is that you have a shorted transistor on your CRT board. You have 3 that will be located on CRT board and sometimes 3 on Main board. You need to look for the Green bias transistor. A three leg blk. trans. is shorted or going bad.

I think either your red and blue filaments are not fully intact causing the green to take over or you have other electronics like subwoofers too close to your tv.

Try degaussing your tv, it might have a degaus button at the back or check the menu.

If you've tried those things without luck, respond with more details.

Hope that helped.

Vertical color lines


I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.
