Question about Televison & Video

1 Answer

I have a 1985 Zenith Space Command Color TV. It has developed thin white lines at the top of the viewing screen. The rest of the screen is clear. Is it something small or am I looking at a new picture tube. I hope it is something small because I love this old tv.

The picture tube is fine.
Those whites lines at the top of the screen are caused by a dry or leaky capacitor(s) nearby the vertical amplifier IC.
Let me know if you require further assistance.

White line across screen


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.

Take it to a repair shop.

Hi i have a Zenith z20la7r lcd tv.Leave it on overnight next day i notice a white appearance in the background of the screen and some color stream at the top. can this problem fix?. is it the board or


I doubt you will damage it unless black or bright blue on screen which could burn the image.

Before trouble shooting I would call Zenith (they are LG) and inquire if this is a known issue in this model and also if any software upgrades exist for this model.

32 INCH ZENITH PICTURE IN PICTURE ABOUT 15 YEARS OLD.PICTURE DISAPPEARED AND ONLY HAVE A THIN WHITE LINE RUNNING ACROSS THE SCREEN.THE SOUND STILL WORKS FINE. IS IT WORTHWHILE GETTING IT REPAIRED ??


When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Please rate my help++++Thanks for using FRIXYA

Black screen ecept for thin white line around all four side. Channel buton changes colors in various section of screen. On/ off button does not work


I found the solution on mine. To restate, I just saw a thin white border around a black screen. Pressing the channel up or down buttons changed the screen, in some kind of test mode to shades of gray, and red, green, and blue. I started finding a solution when I noticed when on one of the color screens, that the volume up or down buttons brought up a new menu for color intensity. Finally, I got back to the thin white border screen and pressed the arrow keys in the top half of the remote. Finally a TV screen and I pressed the enter key! Voila!

Thin red line on Hitachi plasma


If it goes all the way from top to bottom, you have a bad panel. much to expensive to repair

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)


I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.

Zenith 60'' LCD TV a blue screen is not sky blue it looks dark blue to black


Go to zenith.com, look under the service icon at the top and then you should see a listing for "Class Action Lawsuit/Settlement". If you follow that link, they'll have specifics listed for this suit that was brought against them (including tv model #s included in the suit). There was an agreement reached to fix/replace affected t.v.s, court date was in Feb. I believe, and just waiting now until they post information on how to proceed.

Good luck and hope that helps.
