to mess around with the factory service codes... this will effect the programming of the computer brains that run most all modern tv sets and will void your warranty if you do something to it which results in you needing to call in a service tech. For picture tube tv image alignment, it sometimes requires to physically move the yoke on the back of the tube which presents the possibility of electrocution... even if unplugged... as the condensers can hold a sizable charge, especially on bigger sets. Also certain test equipment may be needed to properly do the job.
Finally... this kind of info is what tv repair people pay thousands of dollars for when they go to manufacturer sponsored repair classes to learn how to repair certain brands along with getting a book containing these codes. Good luck in persuading someone who spent a lot of money for this info to give it away for free.
try giving us more info as to what the problem is, what kind of tv set and how old, and do you have the original remote (you would need that anyway to get into the factory codes). May be someone can help you tweak it without getting into the sets coding.
I have read, on line that there are special codes that can be entered by service techs. for aligning tv's?
Has anyone heard of this? If true I want the Toshiba service code.
