Question about Sony KP-46WT510 46" Rear Projection HDTV

1 Answer

Convergence and lamp problems?

Hello, I have been reading these forums for a couple weeks and have come to the conclusion that I am having convergence issues on my KP-46WT510. What I can't figure out is for the last couple months the screen has been displaying a red hue that is barely visible with a picture, but is very bright when the screen is blank. In addition, there are red "arcs" on the screen. Just a couple weeks ago the picture will be displayed for about 5 minutes and the red hue completely takes over the image. Are these problems something I can take care of myself? Any help would be greatly appreciated.

Well I hate to be the bearer of bad news but besides the convergence issues you have a bad red picture tube. Us techs refer to your problem as a 'floating grid' in the red picture tube. More bad news is that the tube is no longer availible. The only solution is to have a professional remove the red tube assembly and ship it off for rebuild. A company called Video Display does this work reasonably and I've sent several to them with great results. It takes about three weeks and the whole repair is very spendy, around $400 to $500. Sorry for the bad news.

Replace Both of your STKs if they are STK392-110s do not go back with them use STK392-180s better ICs, The 110s fall apart and do not hold up.

Hitachi 43F300 convergence


Hello,
Do not replace whole convergence board.Because convergence data stored in old board cannot transfered to your new board.Means in your new board there is no convergence data.Unless you have the service manual and know how to get service menu.

I believe if you have convergence problem one of your IC (STK) is bad along with couple of small
Value resistance.

Dont forgat to Rate!

Good Luck

51mp392h Blue Convergence Problem


Hello rogeuryder,

This is the one thing that even make TV repair persons shudder. You don't really have a convergence problem in the normal sense. The convergence works. What you have is a misaligned convergence situation which any documentation and or book on TV repair will tell you that at this point manual convergence adjustment is needed and the only thing you will have to do is keep trying to adjust the convergence until you get the center aligned, and then work towards the outer edges using both static (Center) and dynamic (outer edges) convergence techniques.

As this may sound it is; Very Very Tedious.

Here is something that may help you:

http://books.google.com/books?id=ttBofTJM7FEC&pg=PA112&lpg=PA112&dq=static+convergence&source=web&ots=hyUMeeY9s6&sig=DZm27q1aMbLiwKA__fyysBd2yUE&hl=en&sa=X&oi=book_result&resnum=9&ct=result#PPA112,M1

I have used this book when I use to teach TV repair. I hope you discover what I am tried to convey in my e-mail, this is no longer a question of can you fix a TV? It has become a question of do you have the patience to adjust a TV.

Good fortune in doing this, you will succeed if you just take your time and do static convergence first and then do the dynamic convergence with the manual controls. The procedure will be in the service manual.

I hope this helps

Thank you,

Resetting convergence daily on Toshiba 43h70


Hi Mark, tough call without putting a scope to the circuit, either the convergence IC`s are going bad, signal from DCU is going bad (digital convergence unit), or possibly bad solder somewhere in the convergence circuit, I`m afraid your going to need a tv tech for that problem, BMW Rider
