Question about Televison & Video
My TV convergence is messed up and looks 3D like so many others.
From searching this site, I found the most likely problem is my convergence IC's. The pico fuse supplying the left IC was blown however the right one wasn't and none of my resistors seemed to be blown. I replaced both STK392-040's and the pico fuse on the left.
When I powered up the tv, it looked exactly the same as before the repair and the right pico fuse was blown this time.
Do you have a clue of what could be the problem.
I also would like to know which resistors usually go out with the IC's.
The old IC's had the letters B2H12 at the top right and the new ones have B3C25.
Thanks for your help.
Did you remove one side of the resistors from circuit to check them? If you leave them in circuit a blown resistor will test good as it will read the resistance from the surrounding resistors. Usually its the 3.9 ohm resistors identified bu the bands orange,white ,gold and red. and also the 150 ohm identified by the bands brown, green, brown and gold
