Dynavin Noise Fix
From the Dynavin message board:
“At first, we are very sorry for the design errors.
After one week of learning and survey , we found all the background noise and station interference noise are high - frenquency noise, but we used the common low – frequency speakers for testiong, so we did not detected this bug before.
Now we have found the solutions, that is to replace two capacitors and two resistances in the mainboard, in this way the background nosie will be reduced to 25% than before, station interference noise also will be lower substantially. we have sent the solution to our distributors , please clients whom has this problem contact with our distributors and consult with them to deal with this issue.”
“For managing it, we need to open the dvd player ,detach the dvd loader and see into the mainboard. So we highly suggest the client find expert to do this work.”
Doesn't look like an easy fix.
