Main electrical discharge | Has different versions. transferring components from one to another using the old board reference (if you have the other version on hand*) | Adaptation: place or remove regulator q410 and adjacent ones (cap and smd resistors around it), replace the ic1603_ut memory and remove and add some resistors close to the 2 lvds connections (with a lot of patience, compare and replace little by little so as not to get lost). works perfectly. If you don't replace the image memory, it will be turned to purple. God bless us! bysc | |
