Are they very thin vertical lines? If so, you most likely have a bad plasma panel. A picture would help to confirm the diagnosis

I have a Sony KDFE50A10 50 inch HDTV When I turn it on for it has the lines verticle on it it takes a few minutes and then clears...tv or cable?


Hi,if its a an LCD RPTV it sounds like a light engine problem.Basically your tv uses 3 LCD chips that create the image .Each chip is like a tiny screen that blend together to get the colors and picture right.They are green,red and blue.When they start to fail you will start to get color discoloration or vertical lines.You will need to replace the light engine.God bless you!

Screen fades to blue.


The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).

Sony 43 inch rear projection tv, I have lined up the convergence but still seeing red and green around edge of the tv on the images, seems fine in the middle of the screen though.


Always start at the vary center of the screen with Green. Position Red over Green, then Blue over what now will look yellow. If all is perfect except the outside, you will need to adjust "Mid-Size" until the middle is just as far off as the outside lines. Then adjust the main "Size" adustments to match. Go very slow or you can make a mess of it.

Sony 60" LCD projection TV has yellow screen discoloration


It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

Convergence is when you aim all three of the projectors, your tv has three, so that the images they produce all line up with each other. This usually doesn't generate a white line across the middle of the screen though, there is a button on the front panel of your set that automatically converges the three projectors, you can try using that.
