Re: Toshiba 40L1333b Bad psu
That is the typical MUR series PFC diode that failed as shorts, if you search badcaps' site with 'MUR *' you will see that happens a lot on SAMSUNG P.S., you will not get PFC boosted Voltage when it failed.Last edited by budm; 05-21-2015, 08:47 AM.Never stop learning

Re: Toshiba 40L1333b Bad psu
may be the brand or the series that they were using are bad.
600V seems to be too low for me, it should be 1000V.Last edited by budm; 05-21-2015, 10:03 AM.Never stop learning
