Hair like black lines on bottom of screen

I noticed cracks on my picture but it is not on the surface of the screen. You can't feel any scratches on the screen but they are on every channel and video. They are black hair like lines that are on the bottom of the screen.

It could be either something on the mirror or perhaps the coolant has leked from one or more of the picture tubes. You would have to gain access to the interior of the set to check both of these possibilities.

Hitachi 51UWX20B spider web like lines help


I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck

Sctratches on 46" lcd tv. Two of which is noticeable in dark scenes.(White lines) How do I fix this?


used thse methods myself
Vaseline Method
  1. Clean the surface of the screen.
  2. Take some Vaseline and fill the scratch with it.
  3. Gently wipe off the excess Vaseline, being careful not to press too deeply so as to leave some inside the scratch.
  4. Voila. This works because the optical density more closely matches the LCD face than air.

Pencil Eraser Method
  1. Find a pencil with a clean, soft eraser. It must have no pencil graphite on it as you won't want to smudge that on your monitor.
  2. Lightly rub the eraser over the scratch or nick on the screen.
  3. Keep rubbing until the scratch completely disappears

JVC TV 27" Black line on top of screen


This is for the original problem.. Not the second post.

It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.

This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.

Toshiba pic problems


Hi, have you realy look at inside the picture tube, it sound like you may have dride out oil in on of the tube, if the line's or still there, look , this or repairable, you must pull out the crt, wash them , replace the oil and put it back together.
It seem easy, but it's not, will notice at the end you will have to re iline the picture tube and some time it will take 10 hr's.

Look again and let us know.

Scratched tv screen


I replaced the screen on my 62 inch projection TV for about $50 and the the picture quality is good! Have a sheet of plexiglass cut to the EXACT size needed. BEFORE installation it MUST be frosted on both sides by either a fine particle sandblaster or by sanding it VERTICALLY on BOTH sides with a power sander and a fine grade paper.
If this is only an OUTER protective screen and the image is projected on the inner screen then DO NOT frost the replacement screen, just install it.
