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

Re: Screen goes green with white vertical lines

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.

Re: Screen goes green with white vertical lines

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.

Just got this tv from friend. has no remote. screen is black. sound is good. when you push menu button, white line goes across horizontally the screen.

The horizontal line indicates the vertical deflection circuit is not working. Either the set is stuck in service mode for adjusting color (turns off vertical), or the deflection circuit has failed.

Some RCA TV sets have a "Service" switch in the back, down near the bottom of the set. Most of the newer sets use a combination of remote control and front panel buttons to get into service mode, and that can be turned off by unplugging the set and plugging it back in. Try looking for the mechanically operated service switch in the back first.

Line across middle of screen.

The line of color is due to a failure in the vertical circuit. The main suspects are the vertical Ic AN15525A and/or capacitor c308 220uf@35volts
If you have the capacity to do so, you should check the other electrolytic capacitors in the vertical circuit which are USUALLY located near the vertical IC in most cases
you can purchase the part at
or mcm electronics
