Where/how can I get a replacement copy of the instruction booklet for my LG
video (model no. W903H - G-Code), which  I bought it in Australia approx.
4-5 years ago. How much will it cost?

Hello sr030377-ga,
  
Thank you for your question.


The Owners Manual (instruction booklet) for the LG Video Model No.
W903H - G-Code is available for download from the LG Electronics
Australia Website.
There is no cost for this manual.


Here is the direct link to download the LG Video Cassette Recorder
with G-CODE - MODEL W903H - OWNER’S MANUAL
http://au.lgservice.com/jsp/common/download.jsp?DOC_ID=KROWM000001041&FILE_NAME=KROWM000001041.pdf&ORIGINAL_NAME_b1_a1=W903H%202AL1L.pdf&FILE_GUBUN=I


I downloaded this 36 page manual and verified that it was the correct
manual for the model you require.


Should the above link fail to work you may locate the owners manual 
by going to the LG Electronics Australian Website
http://au.lgservice.com/

- Choose “Owners Manual”
- Choose “VCR” where it says Product
- Enter “W903H” where it says Model Number.
- Press Search

Choose “W903H%202AL1L.pdf” to download your manual


Search Criteria: LG Electronics Australia
I then searched for the Owners Manual


I hope this helps. If anything is unclear please request clarification
and I'll be glad to offer further assistance before you rate my answer
and close the question.


Best Regards,
Bobbie7-ga

Fantastic!
