            Lucky for you I have this spare main board sitting on my desk. The chip is labeled 4435GM on mine.

              That will probably be a Fairchild FDS4435 (I have used this MOSFET on other boards before.)

                VIZIO or the Westinghouse board?

                    Q in the refdes usually means transistor. IC is usually either IC or U.

                    Besides, if an EEPROM ever burnt out like that, it would very likely be caused by a very bad power supply or lightning strike.

                          Hi Ricosavy.. Did you ever fix this unit? Which mosfet did you use? I have the same issue.. The mosfet is smoked.. I was going to replace that then attack the ribbon to see if I can find the short..

                            Sorry for delay in answering did not notice the question.the answer is yes i replaced it also had a shorted ribbon they short out in front panel.if you take off the front cover you will see which is causing the problem.
