repair sony dvd remote control RMT-D175P |

My remote failed to work without any reason. There is no IR signal coming out from it. I've checked on-circuit the forward and reverse resistance of the IR LED which read normal. I don't know if there is a chance to repair it myself.
It is a simple circuit with only a few components:
one SMD IC with 20 pins, with label "ET0A8" (or ETOA8??) in line 1 and "F4B4A" in line 2;
one X with label "4.00K" (yes, it is not 40.0K, at least the label is so);
one SMD R with "2R2" on it, on-circuit measuring with cheap DMM read 3R8;
one SMD Q with "ZG" and then a vertical "DA" next to the "ZG".
Can anybody has any idea whether it is possible to find replacement of these components?
