In the back of the TV, there is a controller that you can use to manually set the strength and focus of each color.

Dominant green colour


The fault should be of its video output section circuit. A loose solder terminal at the green color output can cause the fault. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

Green color projection is lifting from the bottom left corner of the screen. Convergence adjustment for the green projection is unresponsive


Howdy,

The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number (STK392-110. When Convergence Output failure is
detected, it’s recommended that both IC’s be changed.

Thanks for choosing FixYA, Big Irish.

People's faces are green, seeing blue and green colours in centre of tv


hi,
it s due to damaged convergence IC.
There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. T they are located on the signal board (on the left as you look into the back of the set).Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.

Toshiba 40who8b convergeance problem


Good Day, harri1234;
Sounds like a convergence problem.
Convergence Output IC Failure
Corrective Action: Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version.
Good Luck, Big Irish.

Convergence


sone tv's have fuses on the convergance ic's so if the ic fails the fuse goes also. the fuse or fuses can be near the ic, or can be located also in the power supply. I have seen that most times the fuse does not look like your normal fuse. they call them pico fuses. the look like small like resistors. i have seen them all white, all yellow, & all green. if you find them they are usually marke in amps, so replace with the same amp pico fuse. good luck
