My convergence keeps going out, I can readjust in the convergece user menu, is there a service tech adjustment, or do you think I need to replace the convergence chips, seems like it changes back and forth by it self sometimes.... thank you very much for your time...

    Have a Toshiba TP55 H60. Tried to turn TV on and right light would only blink. No picture or sound..just blinking red light. After a bit, the TV did come on but the colors are skewed and has ghosts. Can not set the convergence on the menu...does not change at all. What is it and is it worth fixing??

How to fix the convergence on a toshiba TP55D81 tv using the remote control


The convergence is adjusted with the remote by entering a tech menu and adjusting there====if convergence is really bad adjustments are not going to fix it.

The set should have in customer menu a limited convergence adjustment with up to nine points where you can adjust---if it will not adjust there in some way----convergence circuit needs repair.

Do lamps have adjustment? I have a yellow and blue rainbow effect along bottom of screen. I am pretty handy and well equipped.


This would be a convergence adjustment. Check your user menu on the tv. Look for an item under video settings for a something called "Converge" or "Convergence". See if you can adjust it enough to fix the problem. If not, you may need to access the service menu and adjust from there.

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

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 $200-$400 Be sure to vote/rate me if this helped Thanks!

I'm having a problem with my Toshiba 57H81 Rear Projection TV where there is to much green in the picture. Adjusting the tint and colors only helps some. I notice when I turn the TV off rather than a ...


Two things---first if you don't mind give me a vote here--I am rated on how many problems I fix

Second---with the original remote go into the customer menu and select Convergence---see if you can adjust the other problem that way---I can if that helps you email you the instructions for going to the tech menu to adjust convergence all over the screen and and saving those adjustments----if you find the convergence will NOT adjust in some area of the screen you may have a convergence problem.

I would appreciate a vote here for my help and if you need the directions for the advanced convergence let me have your email.

Not able to adjust convergence


Hello there, its possible it is way out of adjustment where you are no longer able to see it.
I don't know if you want to play with this, because t can be very frustrating inching each line into the proper alignment and it maybe better to call a repair person and pay them and also allow them to suffer in that time consuming headache.
I hope this helps.

Convergence problems TOSHIBA TP55H60


you need to replace the convergence ic's these are the stk-xxx-xxx chips found on heat-sinks
on or around the main chassis don't adjust the tubes or anything else this will only make things worse after you replace them you can do the user alignment also check the values of the resistors in the circuit as they may be off now pay close attention to the resistors that have a value less than 10 ohms these are critical to the correct alignment if in doubt replace the resistor.

Red is way out of convergence/alignment


If the convergence adjustment is not moving the beam chances are the convergence IC(s) are defective. If you know how to solder and understand TV safety you may be able to fix it. With power disconnected remove the back. You should see two large heat sinks with large ICs (3 by 6 inches) with about 30 leads going through the circuit board. Numbers on the ICs should usually be something like STKxxx-xxx or some variation with x being a number. These ICs control the position of the three beams. If they go bad you can't adjust one or more beams. Replace them both as you don't want to get in there again in 3 months. Cost is not that much. http://www.tritronicsinc.com or http://www.partstore.com should have them at a reasonable price. Before replaceing the ICs look at the circuit board closly for cracked solder joints. Resoldering any bad joints might just solve your problems and avoid replacing the ICs. Good luck and remember safety.
