I have a Sharp LC-32HI5432KF lcd tv ( UMC TP.MS6486.PB710 mainboard ). There is briefly blue lines at bottom of screen on boot and then just a blank screen. The backlights seem to be working ok. I tried firmware from UMC support, three different bin files but I could not get any to work. They did not come with a UMC_KMODE.txt file, do you know if this is needed for usb upgrade? I know firmware might not fix it but worth a shot lol.
