Re: Vizio M65-C1 | Logo appears for 10 seconds then off




Fixed. Solution:

1) Protected nearby electronics with aluminum tape (had on hand. Kapton likely better to use).

2) Applied reballing liquid flux around edges of the BGA chip (board has two BGAs, did this process on them seperately)

3) Used 1500 watt heat gun at roughly 6" away. Moved in circular motion.

4) Once I reached a temp of 150*C or 302* F, I slowly moved the heat gun closer and bring the temp to 235* C or 455* F. Advice I found online indicated...

I have used the search, and am stumped.

My Vizio M65-C1, Vizio logo appears for about 10 seconds then goes off.Power LED blinks 15 times then the TV powers down.

I have read through many threads on the M65-C1 including the following threads. I feel like I must be looking right past the solution to my problem:
