Hi! I have red led problem on my VU+ DUO genuin BOX. U801, C807, C814 and C850 are replaced. Voltages on F803, F812 and F813 are OK. My problem is a short cut to ground on C819 and C820 (poth pins of C819 and C820 are connected to GND when tested with multimeter). Actual I desolderd R811, U802, C819 and C820 but still both pins of C819 and both pins of C820 are connected to GND. Cant find C817 on your "VU+ Duo P801/5v2 informatuion" but C817 also both pins are connected to ground. JTAG Connection switch to green "connected", but can not access memory. Any idea what I could test?
