EEPROM swap in convergence module box (Hitachi 55FX20B)
 

Which EEPROM IC can be swapped from old to new module? Just finally
got a OK to replace this module ($400 cdn!!) even we warned owner to
stop investing in that old crap (blue tube is weak).

Original fault: convergence splits apart in two directions very
intermittently, way off not in that way like with all convergence
yokes unplugged. In fact the resistors were replaced because of
extreme pull to one side too long long past. That module was worked
on twice, once by previous shop, once by myself (more caps to no
avail).

This is a small tin box with 4 plugs behind the front panel on the
floor of the cabinet.

Thanks & cheers, Wizard

May be simpler to just order the registration overlay and setup the product
that way.The service manual will indicate which is the main Eprom in the DCU
Assembly, if you want to go that route.
