Don't know about any factory reset option, however...
Maybe the RF modulator is switched off. Try this to check...
1) Press POWER on the front of your VCR to switch it to standby.
2). Press and HOLD the PROG "^" or "V" on the front of your VCR for more than 4 seconds.
3) This should turn on the RF Modulator and set it to CH22.
You can obtain user manuals online at LG's website..
