Re: Samsung LE26B450C4W Dead PSU -* Fixed *

Set now working Appears zener diode ZM801 was spiked (and was shorting internally) when UM801s pins were shorted or had failed (and they killed ZM801fault finding).

After some help with this TV. I got the set from an auction and it is dead with no signs of life. The set has the BN44-00259A PSU fitted. I have done the usual checks and found that the second main fuse FM802S was blown, a closer check of the board i found that UM801S (ICE3BR0665J) had damage to pins 3 & 4 (looked like shorted with a test probe by others).

Replaced the IC and checked all diodes etc (only have access to standard DVM at moment) and all checked out. Replaced fuse and powered up set still dead but fuse now intact. Checked out voltages on large cap as another thread...
