Re: help pls samsung la327r1b

It's odd, but some types of mura are only visible under the right conditions. In the service menu you can access test patterns, what do these look like?

[vinceroger69]

Re: help pls samsung la327r1b

the voltages are usually marked on the board itself by the sockets make sure your multi meter has a good battery in it as well.

Re: help pls samsung la327r1b

Re: help pls samsung la327r1b

double check your meter battery i have been caught out before chasing a low voltage changed the meter battery it then read ok.
