Is there schematic for Turboexpress?

TE differs slightly from PCE and TG-16 in that it has internal sound, LCD, and tuner support. The video is what I wanted to see as LCD has analog RGB plus inverted sync, I wanted to see the schematic of that area to see what I can do rather than tapping directly off HuC6260 chip. It's much easier to repair damaged trace than to repair broken pin off the chip.
