    I checked the areas, everything is fine

    I used the Hitachi STK's

    still no luck on vertical blue convergence

  • JohnTVman Jan 03, 2008

    can't get into that site, so, is the problem coming from the power supply board?

  • JohnTVman Jan 04, 2008

    I checked the power board this morning, then turned the tv back on-now No Power only clicking

  • JohnTVman Jan 04, 2008

    the red standby light stays on

  • JohnTVman Jan 04, 2008

    oily substance coming from power supply board, from unknown part

  • JohnTVman Jan 04, 2008

    all checked good

    also cleaned board & rechecked fuses

    would the red standby light still stay on, all LED's are on, could it be the power regulator?

    your assistance is greatly appreciated

  • JohnTVman Jan 06, 2008

    the power is now back-2 pins were touching & caused shutdown

  • JohnTVman Jan 06, 2008

    yes we are back to no blue control now

Changed ICs Chips but still got bad convergence

After the IC replacement, convergence adjustments should be done. If you wish to get some details; visit the site linked here. Pull up older posts. Details of this adjustments are given.

I have a Toshiba CT-90121 and my convergence is off. I can adjust the blue and red in the menu but cannot aline them with the green crosshairs. Do I need a new green projector or something else?

You need to remove the convergence Board and repalace the convergence IC's and and replace electrolytic caps and check for resistors that have changed in value. You can getb the parts at com or just purchase a new board at .

My tv has like a blue tornado going across the screen whats wrong with it?

Have the convergence Ic's replaced. Your blue convergence IC has failed, when replacing have them both changed as the other one handles RED and Green convergence

The Screen looks 3D & Colors don't line up on my big screen????

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

I would change both ICs STK392-110 and also the 3.3ohm 1 watt resistors and the 1.8 ohm 1 watt you would need 2 of each resistor. Then your convergence would be new again. You can get replacement ICs and resistors at the following link with free shipping and free instalation instructions with pictures.

43H70 Blue Convergence out of line and will not line back up

If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
