The blue tube if fine
you need to replace two convergance
chips or have a shop do it.99.9% shure

the chips are cheap around 20.00-30.00
etch and even less for the generics 10.00-16.00 ,so dont let the shop charge you
to much for the dirt cheap parts.

I have a yellow line on the right side of my Toshiba 50 rear projection TV and yellow shadows around people


It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.

Cross hairs


Hello, You need 2 convergence ICs if you cannot converge the red and blue lines on top of the green "cross hair". You should be able to use the front panel controls to move the red and blue around. If you can move them around and they just won't move completely on top of the green then the ICs are bad. The ICs are mounted to large,finned heatsinks and have numbers that start with "STK-" and have numbers following. These parts are available from http:\\www.tritronicsinc.com.

Blue shadow


Good Day,jmurf1037;
Yes, you have a convergence problem.From what you say it sounds like the Convergence IC's have failed. Part number 267P150010, STK392-570, replace both IC's. They are on the middle board secured to a large heat sink.
Good Luck, big IRISH.

Toshiba 56H80 Convergence Problem?


There are 2 large IC's in your set and one of them has burned out. These are called convergence output IC's and are usually the STK392-010's. A good idea would be to go ahead and replace both with the newer, upgraded STK392-150 IC's. A good tech can change those IC's in about an hour and a half, and when I do a housecall for a set like that I charge $150, but shops in your area will vary so be sure to ask around.
