Work is needed on the convergence board; Could be just resistors or the ICs and resistors. Seems to be an ongoing issue, especially for sets that have their brightness levels turned higher than usual to compensate for room ambient light..accordianman

Hitachi 42 in tv approx. 5 yr old. from center to left of tv is out of focus. have tried the magic focus, does not help . there is a green image next to the original image.


Convergence output ICs starting to fail and may also have a resistor or two that changed value. Would be best to hire expierienced tech as there are many necessary adjustments after changing parts.

Hitachi 57F500A Projection Color TV all of the sudden is very blurry. Tried magic focus with no help. Checked all connections and there is nothing wrong. All other TV's in house work fine.


Have the convergence IC's replaced in this model. They are the two large Black IC's located on a large alumium heatsink. Have replaced.

Thk please leave comment.....

Hitachi Projection TV 57F500A red looks double.


You need to replace both of the convergence IC's and any bad resistors around them that protect them from damaging the power supply.

This repair can usually be done in the home and takes about an hour; I have done hundreds of them and now is a slow time of year for TV shops; look around if you are not able to do this repair; you can buy the chips on Ebay for less than 15 dollars for a pair plus shipping.

This is a very common problem in projection sets.

This is usually cause by bad convergence IC's with part# STK392-110. There are two that need to be replaced.

My Hitachi 57F500A Projection TV has developed what seems to me double exposure and it different colors than the normal headers,i.e., ESPN. I have tried to just use the DVD player to see if that would cure...


Just to clarify, it sounds like what you are saying is that the image appears to duplicate in either red or blue along the edges of the image (especially white lettering and probably increasing along the boarder of the TV). This is resolved by converging your TV. Convergence will drift normally on large screen projection TV's over time or through moving them. The Hitachi 57f500a has a feature called "Magic Focus" (pg 36 in your manual) which will auto converge the image. If the auto converge feature doesn't work, on page 37 in your manual, it explains how to converge manually. If you do not have the manual, I have the image of the pages below. If for some reason this doesn't work, please provide additional info and detailed prior to rating the help.

Hitachi TV HELP!


Hi, magic focus button is behind a small door on the front of the set just below the screen, I don`t think it is going to help I believe your convergence IC`s have failed,try pushing it once and let it finish, if still 3d image you need to call a tv tech, good luck, video-tek

Magic Focus does not work.


Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
with upgrade Stk394-160E Hitachi part # CZ 01341,change both
for reliability.....check B+ feed resistors for over-heating....T.
