Reading the model number off the back 719C1, I did a Google search to see if there's any info on it, I have found there's a service manual for it on the SAMS Photofact site on this page
https://samswebsite.com/en/photofact...ndex/id/182072 which you can buy for $22, also the manual is available on this site
http://www.smcelectronics.com/samsclrtv3.htm for a much cheaper price of $7.50. Apart from that no other info or pictures on the Google search so it is indeed a rare set!
