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. "Jason D." wrote in message ...
