Hitachi 50ux26b projection TV, the color lines separated...


It sounds like a convergence problem; either bad solder connections at one of the convergence Ic chips or a bad Ic. if this was helpful give me a vote----if one of the chips is now bad it will have to be replaced(usual thing is to replace all the convergence ic chips---most use two and a few 3.

The blu display on my sony 65" tv is arched, making the convergence adjustment in-effective.


its failure of Convergence Out IC chip and requires replacement.
TV has 2 IC chip in convergence circuit and I would recommend to replace both at same time.
Let me know exact model of Sony 65" TV to provide you more technical info.

60PP9352 60 in. Rear - Blue convergence issue


Replacing only the ICs MAY solve the problem, however, many people have also had blown resistors requiring replacement. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.
You do not have to replace any transistors to fix this convergence failure.

43UWX10B problem with green


if you have a 2 IC convergence chassis they dont control the green , However if you have the 3 IC chassis the green is controlleed by the third IC these are usually STK4275 or simallar single amp ICs. Which type chassis does your hitachi have? Its possibly related to the digital convergence board if all resistor near the ICs are good. Do you have the service manual? I can post a link where you can get the full service manual if you need one

Convergence chips


The convergence IC or in a sense ,amplifiers and the resistor are output resistors... if they are burning up the current going through them is spiking too high... TO me this is an indication that the "convegence yokes" are shorted. These are coils around the tubes that control convergence. I would suspect maybe that these are shorted to ground somehow. This is my first guess for this problem
