Its not likely to have come un soldered or loose, a lot of times when you move a big screen they have to be reconverged. not because of damage but because of the move in general...i would call a shop and have them come out and re converge it. that what it will take to get it done right

Hi in the convergence to adjust the color the red is above the plus sign in 3 spots and will not come down and they are not straight


does the blue convergence crosshairs move up and down left and right? Does the red move left or right. does the red move up at all. this might indicate a faullty resistor, bad ic or just bad convergence data. let me know i am here to help

I have a toshiba big screen tv we believe both convergents need to be replaced we do not have 300-365.00 to repair it . I know how to solder can I do it myself???? model#57H81


convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Convergence issue, replaced convergence chips, now blinking red power light and no picture


Recheck all of your solder connections for bridging and cold solder joints. Check the large output resistors under the heat sink and the smaller ones to the left of them. Check all of the fuses on the power board. And make sure that you check all of your connectors carefully. Also check that you didn't pinch a wire somewhere.
I am not being mean by saying that if you could power up before then more than likely the power up issue was caused by something you did.

Tv won't come on


Mine is Toshiba 55 TZ, have it since 98', shutdown and red light blinking problem, search the ned and found out, generally a Convergence IC (stk392-110) problem. bought 2 for $15 at suburban-elect.com (ebay). replaced following direction from http://www.casiasfamily.com/repairlog/tp50h15.html

Open back cover, 9 screws and wirings (pls mark), removed(soldered) a electronic board infront of convergence ic. removed IC (stk392-110) (screwed and soldered).

Replaced everything and voila...! it is now working again..
no more shutsdown and red blinking light. Saves mo $400 for a repariman. of course just be careful with static and stuff.
