I opened the display pcb and checked the switches but they seem ok ..also cleaned them.

I cleaned the Boot room and the memory also....

I checked J5 but no connector was in ...

i also removed the connector of the Dc board and put them back in i did all this but nothing happened...the same problem...

i try to enter service mode but no success and than error code e602-0002 back in ....

Is there any other way to make firmware???

Also Teckat in you opinion maybe the dc board or the video board defective?
