Question about Hitachi 60FX32B 60" Rear Projection Television

Open Question

Model number 60fx32b blue convergence seems to be off and shows to curve in from the top and bottom. The convergence screen allows me to adjust the convergence left and right only and not up and down. It started as a flicker at first and now looks as if screen is in a 3D look.

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

Check the resistors right next to the Convergence ICs often 1 or 2 of them go oen when the ICs fail.

Convergence problem


The convergence board is bad in this set. Samsung no longer has this board in stock. You will have to take the board out and rebuild it by replacing both of the STK convergence amp IC's These IC's are soldered to the printed circuit board. They will be standing up against a metal plate, called a heat sink. They are black in color and are about 2" by 3" . They have white lettering on them that start with STK and the some numbers. You get those numbers and go to mcmelectronics.com, enter the exact number of the IC and order two of them. Before you install the new IC's you will need to apply some heat sink compound onm the back of the new IC's. This heat sink compound is avaialable thruogh radio shack. Good Luck

Convergence issue... I tried to manually fix it through the menu option without any luck. The convergence does curve at the top and bottom of the screen.


It seems the solder is broken in Vertical Convergence Amplifiers or it is damage internally. This model has 2 Conv. Amps: 1 for Horizontal (Red, Green and Blue) and 1 for Vertical Convergence output (Red, Green and Blue), if the convergence does curve at the top and bottom, it is because Vertical Converegence output is no good. The Conv. Amp. costs around 20 dlls. Thats why you can not fix it with the Menu option. Good luck!

Hitachi 46F500 and there is a blue curved bar


Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

50hx70 blue projection light is concaced at top and bottom of tv


When the convergence amplifier ICs go bad (STK392-xxx), they RARELY cause more than one color to go out. The fact that the top and bottom of the picture are effected indicates the vertical convergence IC. Replace both, and while you're in there check the bias resistors... it is likely one of these is open. Once the ICs have been replaced (as well as any open resistors), customer convergence followed up with the auto convergence should do the trick.
