The blue printing head is malfunctioning and must be replaced. If you can't recover a head from a junked printer then it will be cheaper just to get a new one.

All my prints come out with blue lines running across the pictures. How can I fix this?


It might be the photo paper you're using, if it's not the specified type then it doesn't seem to work right. All of the ink is in the paper and the camera prints by laser, so I would go after the paper first before investigating a new camera.

My priter prints blue lines across all colored pictures or text.Any Idea?When printing black only,there is no problem.any colored - blue lines are added.I did reintal the drivers,used old and new but...


Have you tried cleaning the print heads or replacing the color cartridge? where as it it printing black fine it leads me to believe the problem lies in the color cartridge. my first recomendation would be to run the clean print head wizard in the printer settings and if that does not work then replace your color cartridge.

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.

Blue tint and lines on screen.


Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
