Question about Mitsubishi WT-46809 46" Rear Projection Television

1 Answer

Fine Yellow Lines

In addition to the bowtie effect that others are talking about, I have fine yellow lines running across the screen. Any ideas as the the problem and the solution? Will repairing the convergence issue also take care of this?

The lines I believe are retrace lines (if I interpert correctly) and may or may not be corrected by turning down the screen controls red green and blue. But first I would see if the 200V source that feeds the video outputs on each crt board is there or low. If so the problem would be a resistor or 200-250V capacitor that feed them. (200V source usually off the HV transformer secondary.

Fine interference lines running diagonally across picture.


Hi There,
Sounds like your Horizontal Output Circuit is leaking current causing diagonal lines across the screen. I hope this will help and thank you for using FixYa!

Thin red horizontal lines across screen


replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

P42W46X Zenith Plasma - No Picture - Mostly Yellow on screen


Mine looks like too, but the line running across isn't on my set, picture looks like this, and the sound works fine. I took the tuner board all the way out and turned the set on and it did the same thing, then I unplugged the top wire on the board next to the tuner board and the screen went black. plugged it back in and the screen came back with the scrambled picture. Anyone know why? Bad mainboard maybe? the left of the tuner board?

I had the same problem with my monitor, saw only coloured vertical lines. I opened it, opened the back of the metal casing to get access to the circuits. There I found a loose connector. I reset it and it worked again!
