Title: LG 50PC1D-EC Power supply components identity needed! YPSU-J012B
Post by: cheeky2 on May 01, 2013,13:26:12

I have power supply from a LG plasma YPSU-J012B LG PART NO. LGE6709900020B has a few components blown namely Q151 and the wattage of the resistor R151 10ohm
so if you know what Q151 is can you let me know.
The 5V standby is not available on the psu which means its as dead as doedoe! Replaced a load of blown caps on the secondary side and need to replace the strw6251 as well!

Just removed it and have managed to identify it as STP6NK90ZFP as casing had blown on it.
I think the resistor i will put a 10ohm 2watt inside

Hi Tv Tony, i managed to get hold of the transistor thanks but have also found that the diode D152 has gone short cct almost certainly as result of other transistor going! Any idea of the value of the diode? Its marked up as a R60 on diode just googled it and haven't found anything so far!
 Any help would be great
