Re: Vizio M43-C1 No Backlights

Just to add that for the D55u-d1, I only did it to one CPU, not two

Re: Vizio M43-C1 No Backlights

I had the same problem as Neilc6 with my M43-c1. I removed the Mainboard and its heatsink, covered the components around the cpu to shield them from the heat. Pointed the heater at the cpu while monitoring its temperature with a laser thermometer pointed at it. Once its temp reached 121 degrees C, I began timing it with a stop watch and kept the temp between 121 and 130 for 5 minutes. Then repeated the procedure with the second CPU. Then let it cool to room temp and put everything back together. Tv is fixed! I don't know how long it will last, but...
