Hi everyone. I'm hoping someone could help me decide if what I have is adequate, and if not, what you think is needed. Of course...leaving it as-is would be fantastic if it will work. We have a small hot tub that we want to put on our deck. The deck was just recently reinforced but not with the intention of putting a hot tub on it. I have included quite a few pictures. The deck itself is made up of the following: -posts are true 6x6 fir -posts are 8 1/2' and 9 1/2' between each post -posts sit on concrete sonotubes buried 18" and sitting on 20"x20" concrete footing -sonotube is attached to footing with rebar -posts sit in 6X6" saddles (post anchor) with 4-6" rebar going into sonotube -beams sitting on posts are 3 (triple) 2 x10" fir beams sitting in metal saddles (post anchor) -deck joists are 2x10" and are 16"OC (some are 14" for some reason) -There is only one row of bridging. They are not offset. They are 2x4" and are at the top of the joist not in the middle. -The joists at the house side for the most part sit 4" into the inside of the house, they do not go deep into the house as in new construction. - The window and sliding door are new. -Sliding door has a steel i-beam (as shown) with 4 - 2X4" on each side. I don't currently have the i-beam stats but if I can get them I will post. -the window has 3 - 2X4" supporting the window header. -Filled weight of the hot tub is 2500lbs, plus add 1000lbs to the extreme for people, so 3500lbs total. If my calculations are correct that would be 71.5lbs per square foot. - The tub is 8x8 feet

My tub has completely stopped working to where the panel is now blank and none of the pumps can be triggered from the control panel or by power cycling the spa. The stereo works, I can control the LED lights from the control panel just fine, but nothing else works. It is a 2013 Sundance Optima 880 with 240vac supply and two pumps. I just had the control panel replaced 6mo ago under warranty and the warranty, unfortunately, expired 5mo ago. Here are the troubleshooting steps I've followed thus far: [list=1] [*]Completely shut off power at circuit breaker for 24 hours and turned it back on. No change in status. [*]I cycled the power after removing the control panel connection to the PC board hoping the recirculating pump would come on, but no luck. [*]I removed the WiFi module that was in-line with the control panel, cycled power and no change in status. [*]Checked power throughout the PC board including incoming 240vac, transformer input/output, and continuity of all fuses. All check out fine. [*]By process of elimination, I suspected that it must be something with the PC board, so I decided to pull it out for closer inspection - after labeling the wires of course. I heard the capacitors could swell over time and you'd see a bulging at the top, but this wasn't the case. I then noticed something peculiar. There is a small integrated circuit chip adjacent to the capacitors that just didn't look right. It was surrounded by what looked like burn marks instead of the crisp green color of the PC board. I flipped the board around and noticed an indisputable dark spot where that chip is. See attached pics. Apparently, this chip is a voltage regulator. [/list] So, my question to this forum: Based on the troubleshooting I've done and the discoloration/deformation of this chip, would you conclude that the source of my problem is the PC board?
