When it just makes just a chime the LCD is under some kind of stress. This is caused from the back metal bracket out of alignment creating upward pressure. Try realigning it to test it remove it. WOW! it now boots up but only if you remove and re-install the battery connection. Now for all you Red and Blue screen people out there your motherboard is damaged with the wrong screw installed or over tightened! No google result will fix a bad trace on a motherboard so stop looking and consult a professional board repair specialist.
