Built in speakers no longer work
we had the same unint in our store with the same problem.
the cause was a manufactior defect.
a heatsink was shorting to a electroletic capasitor on the main audio amp.
fix was to isolate with a non cunductive plastic over the capasitor causing the short.
hop this helps.

Panasonic TC-L32X1 The picture blinks on and off but it still has power
These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.
