You have a component failure in the horizontal deflection circuit thereby sending the set into protective shutdown. It will have to go to the repair shop unless you have some basic troubleshooting skills and the service manual.Let me know if I can assist you any further.

When I turn it on there is just a horizenal line. This is on a Mitsubishi cs 35 ax 1 35" from 1992


hi there, it seems you have problem with your VERTICAL IC, this is similar to all CRT I have repaired. horizontal lines in the middle huh! well the picture is deflected in the center of the screen. it shows your TV is oscillating. means it is good. the problem is that you cannot adjust the picture to occupy the whole monitor. By replacing the Vertical IC it will remedy the picture to view widely. the vertical IC has these many 8-10 pins and mounted on heat sink. Usually mine is serial with LA 7837. good luck on your troubleshooting, hope this help, please rate and vote.

Curved blue lines on screen.


You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

Blue streaks across picture


Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

Hello, the problem regarding horizontal blue line can be around vertical output stage with IC(LA78045). Please check for cold soldering, resolder the suspected solderings. Best regards.
