hey guys first post. quick rundown is got it for 100 on craigslist with apparent backlight issues. after some testing with multimeter found it was inverter board. so 60 on that and it worked awesome for 6 months. i thought it would be smart to update it since one was available. followed instructions and the update failed halfway through. upon restart there is now only black screen and green light. Any known way to reflash the update, a recovery menu that will save me, or anything i can do other than get a whole new mainboard for 130? the upgrade menu no longer comes up. and if i do have to replace...
