Vertical size About a six inch black space at top of screen

To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

If you hit full screen on the youtube video and its not full screen, then it sounds like your monitor resolution is to low.

Rt click on a place on your screen and pick screen resolution, then pick resolution and increase it.

The first number is width, so say it's on 800x600 then go 1024x768

well its all new now could be bad caps or vertical i.c. okay if you have a esr meter check around the i.c. for a leakey cap good luck

There should be a way to go into the screen settings on the set (either from the remote or on the bottom of the screen). From that menu you can adjust the size of the screen, stretch it, align it, etc.

Call 323-767-6030 and I will go through with you.

you might have bad caps or the vertical output integrated circuit, try to locate the vertical ic and check the surrounding areas for bad capacitors.


good luck

I have found an fix for this a capacitor 2494 needs to replaced.

More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.

hi there, you have vertical section prob., repalce imeditely the electrolytic capacitor at the vertical section. do some test and check up. ty

you can use the menu and adjust the vertical size.or if did already but it doesn't work,try to open your monitor and look for a trimmer in the vertical section,then try to rotate by these you can adjust now the vertical size
