Question about Mitsubishi WT-42315 42" TV

Red color shift and ghosting

Thank you so much anyone who can help with this:

When looking at my screen, I have a band of blue along the left side with no ghosting of the picture in that band. In the center, it is ghosted with a red hue that seems to ghost towards the center (i.e something on the left will have a red shadow to the right of it, while something on the right of the screen will have a red shadow to the left of it), and then a band of red along the right side of the screen. It looks as if I have colored transparencies that aren't lined up covering the picture and distorting the color. The tv works fine for about 10 minutes after starting it up cold, then when it warms up it stays like this. Any idea of what is going on?? Is it worth fixing or will it be more expensive than just buying a new tv?

I was not able to find any service or schematic for this model. The colors means that the value is 22.6 volts zener diode with the other blue band indicating where the cathode is.
Could you tell me where or what other components this zener diode is connected to?

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):


1) turn color and tint fully counter clockwise until you have a black and white picture.


2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray


3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.


4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.


5) adjust the focus screen and control grids to match the ones on the schematic diagram


6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.


This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.


However if you do not have a background in electronics please take the TV to a shop for repairs.


I hope this helps,

Thank you,

Picture shifted and ghost image

Try using an input other than the tuner. I.e a DVD player or game system on the front inputs. If the picture looks OK on the other input, your tuner is damaged and will need replaced, if it looks bad also, try unplugging the TV for 5 minutes and then go through the setup process in the menus. If this fails seek a repair shop.

No blue screen

what you are describing is a degaussing problem. It normally occurs if some Magnetic source has been brought close to your TV. Perhaps you have shifted your TV from part of the room to another? Or to another room? Did you or someone place a magnetic source (Speakers, Tape recorder, Walkie talkie, some toy of your children, etc near or on top of the TV? Just remove it. And wait for a few days. The problem will get automatically cleared up, as the TV set's Auto Degaussing circuits will clear the color patches.

Color ghosting on left side

A magnetic field such as would come from a speaker might cause the ghosts but would not stop your set from coming on when it's hot. You may have a horizontal deflection problem such a bad flyback transformer or some other component that gets worse with temperature. You need to have it checked out by a technician. Stargazer
