Who Made Randix TVs 1980's ?

[Dan Schafer]

I found a Randix 13" color TV model CM 1330 just wondering who the manufacturer was? I'm trying to find a close Sam's photofact for it. It has a Goldstar CRT 370FCB22, Flyback # 154-074N, Yoke # 153-047E, Audio out transformer 151-167B. Has a STR 30115, D1453 and Vert out chip is LA7830. Do any of those part #'s belong to a particular manufacturer? I like to give these sets a chance before I send them off to a land fill. I get audio for a few seconds and then it goes into shut down. How do you start to troubleshoot these flyback derived power supply sets when they are in shut down?
Thanks
