IC no channel was found its only White display..its there memory IC need to reprogram first before i connect to the circuit? please help me what the best way to do ican fix... thanks!

Your prob could be several things from tuner to eeprom to microprocessor to missing-low voltages- really- if r/p eeprom GET THE CORRECT ONE from supplier- could be any u/s comp in circuit- there are no magic wands to wave- then again most people say "it's the fuse, or the switch, or the antenna- if not then I'll drop the set to make it work!- & drop the set repeatedly from ever greater heights- & when set is completely buggered, bring it to a repairer to fix in 5 minutes for $5!.

put back old eeprom and suggest looking into tuner fault.either resolder tuner or replace.

It is possible that this set has been "auto-programmed" with on ly one channel detected. Try entering setup and "auto-program" again with either an antenna connected or connected to cable. One other thing to look for is whether or not the set has been locked through parental lock.
