Model # PTH5498 Red and Green horizontal lines show up after the set has been on for a little while. They don't stay but come and go

If it is being fed by a component video source you could have a loose connection. Component sends analog video signals via Red Green and Blue cable. If the blue cable is loose then you will generally get a redish or greenish looking picture. If the cable isn't the problem try using a different input such as the S video input. If this still doesn't fix the problem then you could have a problem with one of the lamps most likely the blue. Hope this isn't the case for you though.

Green line running vertically along the edge of picture

If its a LCD projection TV (such as Sony Wega, Hitachi, Epson, Philips, and some Panasonic, some Mitsubishi), and the green image is in the whole screen or just one part as a blob or a line. Is most probably that one of your LCD Color Filters is damaged (burned out or starting to get busted), I don’t know if you can just replace the color filter, I believe you need to change the whole light engine system or the optical block. There are some places around, I found some on ebay but you should definitely try on discountdashmerchantdotcom their price range $260.00 - $330.00

I have a KP-65WV700 and the screen looks a lil to green

OK, I'm the guy that was having the same problem, but had a blue tint to the screen. I also had blue lines running across the screen, and when I followed the steps below that were posted by another user not only did the lines disappear, but the blue haze vanished as well. My tv looks like it's new again, so you may want to try this:

I have fixed this several times on my KP 65WV700

As Slinteriors posted if it is a thin curved line you need to adjust the screen control, it's sorta like a brightness for each color, and if one color is too high it will produce a thin curved line.

The best way I have found to get to the controls is by removing the lower grey speaker cover front the front of the TV. There are 6 screws if i remember, 3 on each side. Then it snaps off, seems like its going to break but you have to pop it off pretty good.

Once its loose you have to remove a cardboard like cover plate in the center that will give you access to the small controller board.

Now be very careful while experimenting on which knob controls which colors. Turn them very slow, if you turn to fast you will cause your TV to shut down. If this happens, turn the adjustment back to original spot and turn TV back on and take it slow.

Adjust the correct color until the line just goes away. Its easiest to do this with a black screen.

I had the same problem which was caused by a bad solder connection on my Green CRT driver board. The fix isn't too difficult if you've had some soldering experience.

1) Determine which CRT is going out (Reg, Green, or Blue). Looking at your convergence adjustment screen will help.
2) Unplug TV
3) Remove the front panel
4) Locate the driver board attached to bottom of the bad CRT.
5) Locate the two large heatsinks on the driver board, each has a transistor attached to it.
6) Touch-up the three solder connections on each transistor. Adding some new solder helps.

Green spot on picture

Greenish yellow spot only means one thing. You have a defective lite engine. The only fix is to replace the engine. This part is very
expensive. Average cost $835.00 Part number A-1606-008-A

PT-47WX, Blue streaks across the screen?

It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.
