Hello guys, is there any expert here on flash memories??? A few months ago i was brought some receivers, to be exact, the Digital 1000 and 801 models. The receivers had problem with their flash memories(HY29LV160). So i replaced them with new ones.i downloaded dump files from their site and programmed them on my flash programmer into the new flash chips. But when i soldered flash back to board and turned on the receiver it just didnt work. I did the same procedure with other models and did it many many times but with no result.
Yesterday i had a WORKING!!!! Digital 1000 receiver and just wanted to retreive its dump file. I unsoldered it and read the dump on my programmer. But when i soldered it back the receiver that worked 30 minutes ago, it didnt work!! i checked all flash contacts, they r all ok
why when a working flash chip is unsoldered and then put back without being altered the receiver does NOT WORK again??? the same when a new programme d flash is replaced?? what do i have to do to get them working??? please give me your help with these Digital receivers, i would really appreciate it!
