Default Re: Soldering station thoughts and guidelines

I think there is a difference in the 858 and 858D. The 858 is 400W and the 858D is 700W. I recently bought the 858D for 35.00USD. It was a good buy. I purchased this especially to try on a LG LED TV 43LW5700. The symptom was standby LED kept non-stow slow-glow in red. The standby LED should go blue once the TV is ON. I self tested the PSU and determined the Main Bd was the issue. I can't find a Main Bd anywhere. I can get Main Bds with the same board No. but different Part Nos. Anyway I decided to get the 858D as I wanted one a long time now. Removed the heatsink on the BGA and fired it up with the Hot air station. The TV worked and now I am counting the time to see how long it would last.
