Yeah, that’s what I’m thinking as well. I’ve checked all cabling, reseated everything, and no change. I don’t think it’s the backlight because there’s nothing on the screen at all & even when shining a bright light at the screen, there’s nothing on the panel. I guess it could be the inverter, but I haven’t seen any source for parts online yet. The seller (SoCube) has only been willing to repair the unit after I pay to ship it back to them, they’ve been unwilling to consider a refund and there are two days left on the dispute through AliExpress, so I’m unsure how that’ll play out. I’m not keen on sending it back at my expense, getting what’s essentially a refurbished tablet back, and having paid considerably more than I otherwise would have. This feels like a very poor QA/QC job.
