RNS510 - no boot, only backscreen ligh

[vopi]

Hi,

I have problem with one RNS510.
When I try to power on I only see dark LCD with active backlight and after 1or2 min radio power off.
I tried to do reset and reset for flash but still the same problem - dark screen wih working backlight. I can´t put any CD to the radio - it is impossible to flash via CD/DVD

Radio is (label information):
3T0035680A
HW: H42
SW: 2724

I am ready to flash S29AL016 or ST proc with elnec but I don´t know which dumps is good for this repair. Please could you help me what I have to do for solving this problem??

Actual state:
I flashed S29AL016 - still the same
I flashed ST10 with 29F400 - still the same

is there anybody who have full backup/dumps for this HW version? or know how to solve the problem?

I supose it is a break in the PCB (it is multilayered). I don't know anybody to solve this. Only another motherboard.
