Aaki 42" red line

Hi, i'll need a bit more info to be able to give you an opinion , am i correct in assuming the "new kenwood " is a radio/cd player ? If so do you have a car phone or a hands free kit for your mobile/cell phone ? Assuming the kenwood is a radio the mute wire has to be connected to the car phone/mobile hands free kit , this is usually described in the phone installation directions , how the mute system works is when you recieve a call the signal is sent via the phone system to the radio , which is where the mute wire comes into use .If you have either of the phone set ups i've described post back with there details , make , model etc ,if you do not have this type of system and are using an ear piece then the mute funtion can't be used , i hope this is of some help to you

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

The image sensor is defective. There is no quick fix other than replacing the image sensor.

This intermittent problem is very difficult to rectify. Just contact the authorised service center for Hitachi at your town. The work is really a skilled one, that a user cannot do it with ease.

poor contact in the vedio connector , open the cover and rmove it , clean the connector and reinstall again

Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

use you're remote to enter code mute 183 while tv is on then press 7 for red 8 for green and 9 for blue control. arrows or knobbie will move cursor. if you still can not control the red you will need to change the red convergence ic...press perfect focus to save changes if pf is not on remote maybe on tv if neither you will need to get a remote that has it to save info.

The individual dots (pixels) that make up the picture are controlled by vertical and horizontal drivers that are rapidly switched off and on. They are arranged as columns and rows with these further controlled in time in a synchronized fashion. The line is being caused by a driver that is failing.
Depending on the degree of integration, these final integrated circuits may be part of the display and not individually replaceable by hand. You may only have the option of replacing the screen with the failed part. 
It will be necessary to contact Sanyo (who may not have manufactured the set) to find whether the repair is cost effective. 

I was not sure if the line was going from top to bottom or left to right. the X driver board is for left to right and the Y board is for top to bottom . The Y driver board is a common issue with these sets there is a Y main board and a upper and lower buffer board for the Y axis
