Colored lines at top and bottom when tv comes on and seeing double vision in different colors at all times


If your tv is not a DLP the problem is in the convergence, try to adjust it using your original remote control go to the setting menu then to the convergence section. Adjust the red and blue convergence. you should move the red and the blue in up, down and left, right if this color does not move far enough your convergence IC is already defective. Replacing this convergence IC will solve the problem. In locating this convergence IC you should remove the back cover of your unit but be sure to unplug it before doing this. This convergence IC is attached to a large aluminum plate, it is the heat sink, and it has a marking of stk- ### followed by numbers. You can try to pull it out using a soldering iron and soldering pump but be careful you may damage the board and cause much problem to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards.

Convergence circuit problem


I would clean the lenses with alcohol and q-tips before i try to change an IC chip. My RCA had the same problem. I tried to use the auto convergence and the picture was out alignment. I took off the button bar by taking off the speaker cover and taking out about seven screws (7/64" allen key type) 3 in the front and 4 in the back. Let the power bar hang. You should be able to get to the lenses. Turn the power on and clean them so you can tell when there is no more streaks.
If that doesn't help maybe your convergence IC is bad. If you have to ask if you can replace it yourself you probably shouldn't try it. It take special tools and some practice to solder IC chips. Good Luck.

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.
