Samsung UN55NU6900F Standyby voltage is 1V higher than expected, is this a problem?
This is the zombie UN55NU6900F I wrote about in this original post.
It originally was completely dead with no standby voltage. After some poking around, I found the solder at RM819 (see pictures) failed. I removed it from the board, it tested fine, resoldered it, and now the TV works.
The expected standby voltage at the reference pin is specified to be 11.8V but it's reading 12.8V. Couple questions:
1. What could cause the standby voltage to be 1V higher than expected
2. Is this a problem
3. Could it have led to the failure at RM819, or was that just bad quality work from the factory
