Hi all, I know these monitors are total garbage, but I have a Bestech BTM-13 model that has a perfect tube. Looks like there is a diode that blew up near the flyback .. thought I'd start there ..

I was wondering if anyone out there had a lead on identifying the diode I need to replace it ... a friend with an exact non working monitor could make out ER20 DEC on the diode, no idea what that means. As you can see in the pic, it's located at D418

Any help is greatly appreciated!

I forgot a friend had an exact chassis w/the diode in tact ... it's a HER204, but I'm not 100% sure where to find this particular one, mouser says it's obsolete. Anyone have any idea what might be a suitable replacement?
