Panasonic 32" dead.
M # CT-32SL14J Ch # AP 411, relay just clicks on, & off repeatedly at
plug in. Nothing gone in the power supply, or horizontal, & the SMPS isn't oscillating, getting almost no output on all secondaries. Looks like the Micro, & EEPROM are bad, & Panasonic Tech just confirmed this. The Micro is a 64 pin QIP. Pretty hard to change. Have you guys seen many of these sets go bad like this? Thanks, Dani. |

Panasonic 32" dead.
quirk of fate
static event perhaps, or some random piece of iron filings/manufacturing solder balls shook loose and went where it should not have these things usually just dont fail like u describe or could be one of those chip failures of the 1 in ten million of the MTBF actualy occured, & u the winner! i would surmise it was a power glitch or out of bounds power supply excursion that did the nasty.
