IC module part for Hitachi 50EX12BA?

Hi, we are in the Army stationed overseas. Getting tech support is tough. We are wondering what part and where to order, the IC module for a Hitachi 50EX12BA. We are having similar convergence problems as described in the site where the Red and or Blue bow inwards from the bottom. Can you tell us how to order the part and where to get basic instructions on how to replace it. We are pretty savy and have our own technitians that work with military electronics. Thanks Joe

Here is a link to over 43 pages of parts for the Hitachi 50EX12BA. Luckily for you they sell ICs and if you click on the IC link, it will show you the particular IC number. I'd take SiverDragon up on the offer. ZT3000 "Beta tester of "0"s and "1's"

Part number for IC module Hitachi 50EX12BA?

The Hitache 50EX12BA uses 2 IC's labeled STK392-110. If you are looking in the back of the set, the convergence IC's are mounted on the large heat sink on the right side. If one of the IC's has burned out, go ahead and replace both IC's with the newer improved STK392-150 IC's. These IC's are very common and can be ordered from almost any electronics parts supplier. When installing the new IC's you will need to clean off the old heat sink compound and apply fresh compound to the back of both IC's.

Jumpy Picture on Hitachi 55FX48B

On older Hitachis the most common jumpy picture is loose connections on the vertical output IC. If you can tap on the main board and get it to act up then this is most likely the situation. I believe the location is IC401 and is located toward the front of the set on the signal panel. Not too tough to repair if thats all it is.
