I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...


The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.

Lost picture all color lines are at top of screen


Thats what happened your convergence went out, those parts can be found online for as little as 12.50 a piece. If you are good with solder its an easy fix. I found a guy on craigslist in denver who fixed it for 150
good luck

I found the blue drive tuner..


have you checked for an open resistor or shorted transistor on the blue CRT socket . Usually its a failed component on that circuit board when there is a color issue

Black horizontal lines appear after tv is on for 30 minutes


Kellia,

I had the same problem with our VS-55705 Mitsubishi. It seemed to me that this was a problem of heat.

I unplugged the TV and then took the cover off of the back of the it. I then used canned air to blow off the collection of dust from the components. Then I vacuumed as close to everything as I could without touching any of the components. I then used glass cleaner to clean up the surface of the three bulbs.

I plugged in the TV and it has worked perfect ever since. I haven't put the rear cover back on it yet. That could have been all that I needed to do to fix it. I'm too busy enjoying a nice picture to try putting it back on. Cleaning the bulbs really helped the quality of the picture.

Good Luck!

No Blue. Horizontal Lines.


Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.
