Chances are it's the STK392-110 convergence IC's....check for blown resistors in the area of the STK's also. It's a really simple solder job. I'd suggest buying a desoldering tool (about $30 off ebay for a good iron style with spring loaded "******") and I'd also suggest replacing BOTH stk's and not just the one. NORMALLY if it's only one STK that's gone south - if the TV is on you can see the STK's with the back cover removed, they are attached to large heat sinks, and look like black blocks....ONE of the heat sinks after operating for a half hour or more would be noticeably hotter if it's burned out. Touch CAREFULLY to check for heat with power on (duhhh) and beware that if the STK is failed - the heat sink may be VERY hot. Heat would be the indicator that something has failed miserably.

STK392-150 is an upgrade part# to replace STK392-110, and they will last longer due to higher heat tolerance. If you're going to replace the STK's - get the 150's, and MAKE CERTAIN they are authentic sanyo IC's. The generic **** won't last long.

Hitachi 43fwx20b. Blue color will not reset in auto or manual focus. If it is convergence what and where do I need to look to locate them in the set?


the convergence is an automatic adjustment. if the auto isn't working after you tell it too from user menu,then the convergence amp is not working. this requires a tech or a good hobbiest. most of these amps are just ( stk's ) chips 3 in the unit you should replace all 3 making sire there is enough heatsink compound on them.

Hitachi 43fwx20b Convergence Problems


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Picture has shadows with different colors (red, yellow, green)


Sounds like the convergence needs adjustment. You can do this through the menu-follow the on screen instructions. The idea is to line up the red, green, & blue.

Good Day,

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,
1-800-458-6053, www.bdent.com and ask for KIT10 for your Hitachi TV.
If you want some else to do the repair for you call an Authorized Service Center.
Good Luck, big IRISH.

Hitachi 43fwx20b convergence repair help needed


In all probability, the resistors are effectively fuses and were "blown" when the original STKs went bad. Repalce the resistors and you should have your good picture back.

Tv picture shaped like hour glass


The link you posted has been deleted, so I cannot see the picture you posted. If the sides bow in like an hourglass and the red, green and blue colors are still aligned then there is a horizontal width or pincussion problem, but if the sides bow in and the 3 colors have separated and are no longer anywhere near aligned then you have a convergence problem, both of which should be serviced by someone with experience in servicing projection TV's.

Horizontal hour glass picture


The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
