Question about Toshiba 27A44 27" TV

5 Answers

Horizontal lines across the top of the screen

There are horizontal lines running across top inch of the screen all the way from one side to the other. TV still watchable and works fine but am wondering if this is an easy fix. Only paid $200 for the set and don't want to pay more than $100 to repair. Thanks for your help. David in VA

    Are the schematics posted here?? Does "refer to qualified" mean this is a job only for a repairman?

    I have the same problem with the 21" screen. My tube is about 3 yrs old now. Can you amplify on your solution a bit. What does it mean to dry out a capaciter? Could I do that without a service call. Is that capacitor on a plugin board or does it have to be soldered into the circuits. Do you suppose I could order the parts from the Toshiba folks and repair it myself? Is there some sort of repair manual on the web (like a pdf) where I could figure out where that is?

    same problem on a 23inch

  • Anonymous Oct 12, 2008

    I have several horizontal white lines across my Toshiba 24AF43 and I only had it for 4 or 5 years. I think Toshiba builds these t.v.'s like pieces of **** so you have to keep buying new ones every 4 or 5 years so they can keep on making money! This is definitely the last Toshiba product I'll ever buy again!

    I have a 27 inch Toshiba TV and I have white lines across the top approximately 3 inches. Annoying.

  • javanfriends Nov 09, 2008

    I also have a 27 inch Toshiba with white lines across the top approximately 3 inches. Very annoying. This was my first Toshiba brand and I will not buy another. This was very disappointing. I had looked quite a long time before buying this TV in 2005. I am surprised it did not last longer.

I also have the same problems with horizontal lines about 3" from the top. There should be a recall. Called store where it was purchased (in 2003/04) and they quoted $75.00 to pick up,$40.00 service charge and then the cost to fix it. If I could lift it and take it there, it might be worthwhile however that is impossible.
But buying another Toshiba is going to be out of the question.
Have another tv, Sanyo and never had a problem and it is over 10 yrs old.
Come on Toshiba, when there is a widespread problem like this it should be recalled.

I have the same problem with white horizontal lines across the top of the screen. The problem improves a little as the TV warms up. I sprayed cold spray on Q410 which appears to be a vertical drive transistor. Is this a good enough indictator that this is the faulty part? It's a cheap NTE54 and easy to get to. Any thoughts?

So I have a 50 Lg ( LG 50LN5700). There is still a picture however about every 3 seconds it goes from regular to blurry and repeats. There seem to be about 3 black lines across the top horizontally about 3...

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.

Why has my sanyo flat screen television only got coloured horizontal lines across the screen?

That might be an issue with the TVs picture tube if it was not one of the LED or LCD TVs. Please get a technician changed it. If it was any one of the LCD or LED TVs, then it would be more expensive than you expect.

Toshiba 27

you just say horizontal lines / and across a top of your television.I expect your trouble is the vertical line of your television . sound ok? try trouble the vertical section the check the resistor?

Jvc av-29ts2ek

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck
