I was given a sony kv-40xbr700 tv and there is some picture discoloration down the side edges of the screen that I think might be caused by the speaker magnets in the sides of the cabinet. Also, the picture seems to be slightly shifted down and to the left. Are these problems repairable? If they are repairable, is it worth it?

I too would like to know the solution to this question...we are having the identical problem and Sony doesn't seem to know how to fix it. Although, the picture from the DVD player is perfect, the pictures for cable & video games are terrible. Very frustrating!
Almost certainly it will be necessary to remove the set from any enclosure as access to its innards is gained by removing the rear housing completely.
If you feel around the back edge (hidden) of the bezel, I'm sure you will find several depressions; these are recesses for the screws that must be removed.
Sorry about your Sony problems, their quality has greatly diminished in recent years.
If the display seems normal when present, you may have what is called a 'cold solder joint,' possibly in the area of the horizontal power supply.
This can be caused by normal heating and cooling of a particular spot on the circuit board that finally fractures the solder and making the joint thermally sensitive.
Most component failures, even when intermittant, would affect the display in some obvious way such as distortion, contrast, brightness, etc.
First thing I would try is a degaussing coil. The problem was not caused by the speakers in the TV (they are magnetically shielded) but by some kind of external magnetic field, like speakers or refrigerator magnets. Could also explain the picture shift, if it's severe enough and someone used a strong magnet. You can find degaussing coils here:
They usually come with some basic instructions. You can also make your own and instructions for using one can be found at the same place:

Exact same problem. KV-40XBR800 wont turn on, blinks six times. I am in the process of changing both Ic's part# MCZ3001D with part# MCZ3001DB. Ordered them frm ebay and waiting for the new parts to arrive.
here are the pictures of both chips and after i removed them from the d board.
As soon as i receive the new ones i will put them in. I can't wait to see what happens and i wanted to say thanks to all of you out there for putting this thing up. Thank you very much.
