LV49152 digital audio amplifier for Sanyo DP46840

We recently had to work on a main board for Sanyo LCD TV from the DP series, specifically DP46840.

It had a hole burned in the audio amplifier IC LV49152 and we apparently had to replace it.

It turned out hard to find LV49152 here in the States, so if you find yourself in the same boat perhaps this will help:

I am quite certain LV49152 is also used in other main boards from Sanyo and likely other manufacturers.

Please note it is a bit tricky to solder the IC properly on a board. Pay special attention to providing good soldering contact of the exposed pad underneath the IC - cook it slowly and do not overdose soldering paste!

Hope this helps!
