Question about Emerson Televison & Video

Ten year old emerson 27" flat-screen tv has multiple thin white horizontal lines and has audio

My ten year old 27" Emerson flat-screen TV has multiple white thin horizontal lines across the screen. At times, it is nothing but nearly solid white "fog." The audio is perfectly fine at this point. What kind of repairs does it need? I particularly like the close caption features of it, and I do not have tools to do soldering or things like that. It is very heavy and not really feasible for me to carry, as I have physical disabliliies. COuld you please help me figure out how to fix my TV? Thank you so much!

SOURCE: Emerson flat screen tv with red stripe

The pixels on your screen are controlled by a matrix composed of switches that turn off and on to produce light.

They are located vertically and horizontally, row-wise and must function together to produce everything from black (everything turned on so no light, or very little, can escape) to layers that represent the three colors that are used alone or in combination to produce the millions of possible shades of each.

One of the switches that controls one of the vertical columns has failed and has turned on the entire column that allows red to display.

The problem switch (a semiconductor combined with many) is permanently turned on, probably part of the screen assembly itself, and was placed with others by robots.
The pin spacing on these 'chips' is very small and often makes the assembly unrepairable.

While LCD panels have fallen hugely in price, you may be looking at a parts cost (labor is probably not too bad) that may make you decide to replace the set.

Unfortunately, the once-proud Emerson name has sadly been degraded and there is a lot of their electronics available from companies that specialize in 'refurbished' products, an indication that they have a large failure rate.

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

Your not alone with this problem.
I had to fix mine. The warranty is less than impressive.
The trouble is going to be the Power Supply/Backlight Inverter board.
This is the picture of yours:
11e1946.jpg This is board # BA71F0F01042. Replacement boards are hard to come by.
Fixing the board like I did seem to be the only option. If you need info on fixing it, let me know.

Thin white horizontal line in the center of the screen when the tv is on.


Hi Tim,
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.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

I have owned an emerson tv for two years now. All of a sudden the picture has become very blurry and white. It is not the cable connection and a DVD is also white and blurry. Even the input channels are...


you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

My 27 inch emerson flat tube tv only shows the picture in a thin strip how do i fix it back to normal


You will need to replace the Horizontal IC around $80 bucks for the parts and labor. What happen here is when the Horzontal ic gives out the screen basically folds to the middle. Do not shoot the messanger here but have the TV looked at by a professional locally.

I hope this was Very Helpful to you today please leave your feedback and ratings.

There is only a 1" horizontal line on my tv screen.


This is a problem with the vertical circuit and is either the vertical IC or a few capacitors that have failed in the same circuit. If you can solder you should be able to fix this yourself. The part cost will be in the $20-$40 range.

Update this if you wish to attempt the repair and I'll supply additional details and instructions.
