WT-46809 Inputs show lines across screen

When we switch from TV to other Inputs (Wii and DVD) there are lines across the screen and flickering of lamps. TV shows fine - anyone have ideas on what it is?

1. THE SYMPTOM IS BRIGHTER IMAGE ON THE SIDES AND DARKER IN THE MIDDLE. THE PROBLEM CAN BE WITH RED BLUE AND/OR GREEN. CHECK FOR PROPER CONNECTIONS TO THE "DAG COATING AND CONNECTIONS TO PIN 9 ON THE SOCKET OF THE AFFECTED CRT. MAKE SURE THESE GROUND POINTS ARE COMMON WITH CHASSIS GROUND.

My Mitsubishi TV Model WT-46809 has the picture turn greenish pink after the TV has been on for a little while. What is the possible cause?


These sets did have one common issue where red, green, or blue would do what you are describing.

The set has 3 picture tubes and each has a small circuit board plugged to the bottom of it (bottom of the tubes faces down) and a ground would break loose or a part do the same.

I would examine the picture (see if you can take one and post it somewhere for me to see---picture will tell me a lot).

The ones with the ground broken usually show it more on the sides then in the middle of the screen.

Let me know all you can.

Have a Mitsubishi wt-46809 tv and has a 23 shut down. ARCING is seen between the focus and the screen in the red picture tube. When the HV line for red is removed I am able to see the short as the tv...


Yep sounds like a shorted red crt for sure. You can send the tube assembly to a company called Video Display for rebuilding. They do good work and are relatively cheap. I have dealt with them often and no complaints. When they rebuilt them they replace the phosphor as well as the entire gun assembly.

Mitsubishi wt-46809 46in wont power on


You need to adjust the votages going to the crt's. As the flyback transformer starts to go out the voltages to the crts can go up and down causing the tv to shut off. It also causes red, green, or blue arced lines to show up on the screen. It can also cause some color fading in and out or flickering. Adjusting the voltages can fix the problem temporarily but in the long run it's a good idea to replace the flyback. Make sure you read up on how to do this safely.

Certain HD settings won't work


no the set uses only two settings in the Y, Pb,Pr which it swithes back and forth. when a 480i,480p SD singal is detected it will switch to 480p, when an HD signal is detected it swiches to 1080i. when it swiches the picture scrambles for a second or two. to correct this in your cable box (if it's a motorola box) leave the tv on, press the power button on the box to shut down the box. next press the menu button on the box and the internal menu will show. use the cursor buttons on the box to select "480i overide" use the arrow to the right to select "streached" them hit menu to get out. hit the power button to turn the box back on.
