Strong 4400 / 4450 Circuit Diagrams

klegg

I think this might be in the wrong section, still navigating!!!

if anyone knows where i could obtain a circuit diagram of a strong 4400/4450 model sat box i'd be grateful.

Does anybody know much about the L64724 receiver module that you plug the aerial cable into (on the sat box) from the outside world. Does it permanantly store information programmed by the manufacturer or does it rely on information passed to it from the IF board its attached to...........

The 4400 series was designed and built by Techsan Korea, but they went to the wall about three years ago.

I should be able to have a couple of circuit diagrams by the end of the week

Is that Techsan or Texan... would they be linked to the TEXAT named boxes

Channel Hopper

Nothing to do with the TEXAT stuff, and the 724 demod chip circuitry is not on the schematic, except as a black box.
