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.

if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

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).

51 big screen apex tv, convergence or verticle IC?


If the lines are thin and close together running horizontally, it may be the vertical driver, but that usually takes out the resistor and sometimes the diode in the B+ for the vert. Also you must replace the caps that caused the problem in the first place.
