Hi,
I have a partly working genuine VU+ Duo. No HDMI output, and no ethernet LAN functionality. Lan interface show only continueou green led light. No network activity on the other led.
I have flashed cfe 3.0 as bootloader and firmware Blackhole 2.09.
This receiver does not get an IP number in my Lan network DHCP server. I have no IP conflicts. Subnetmask and IP nr is in same network. When IP nr is static, I cannot ping this from my computer.
I have working Scart output, the box look further normal with starting. It starts the image which is installed.
Could this be a cpu hardware problem ?
Serial console is working. I can also JTAG with Cypress board.
Anyone have clue of what can be the cause of the non-working HDMI output and non-working LAN interface ?
This box has C850, C815, C808, C819 capacitors allready renewed, including one voltage regulator U801.
I hope I can repair this nice receiver and that the cpu is still good.
Does anyone know of a .bin file I can flash with JTAG in which the code tests if the cpu is working (for example, if cpu is good, led becomes flashing green 5 times, if cpu is bad, you see nothing). ?
I want to know if the cpu is 100% good. HDMI and network are they directly connected to the cpu ?
One other question, is the print circuit board 2 or 3 layers (or more ?)
Regards, Erik
