Convergence?? on Samsung SP-403JHA rptv

If this happened suddenly the last thing you should do is try to adjust it back to normal - whether it uses a service menu or manual controls. It sounds like a classic convergence problem. You or someone who knows how to service electronics must diagnose which components are bad. It's likely to be a few convergence amplifiers, and probably so low-ohm resistors. After the defective parts are replaced the set will likely need minor adjustments to the convergence.

If you try major adjustments before properly servicing the TV, when the defective parts are replaced it will need major adjustments to put it right. This could cost you an hour or two more worth of labor added onto the repair costs.

On the other hand if it happened VERY gradually and it is a CRT (Picture tube) based set then this is common as the tubes age and adjustments will likely make it watchable until the tubes totally wear out.

it has happened gradually, over the past year or so now. it's not a crt based one unfortunately,, it's lcd I had it adjusted about 18 months ago, as it went badly out when i moved, and that cost enough just to get an engineer out, and he used the standard remote to make adjustments, which cleared it up. I shuffled it around, and it went out again, the entire picture shifted about an inch and a half to the left, leaving part of the picture missing and a black line down one side.

I sorted that myself, but cannot get the rest to align. Hence why looking for menu codes to re-align.
