Im posting pictures of the inside of the amp that got liquid damaged is there any obvious damage from looking at the picture? I ran the lexus diagnostics and it says amp is ok and i tried everything including reflashing ecu and it def seems to be the amp, i dried it for days and nothing works, looking at the attached pics is there any obvious damage?

 

You're going to need a new amp, don't bother trying to fix this one. There looks to be some corrosion on the area you circled.

I believe I know what the issue is, someone can correct me if I am wrong: Half a year into owning the car, I noticed after a rainy day, I opened the trunk, and half a glass of water would just pour out of the plastic trunk hinge panel. It was really annoying having the rain water coming in. I had to go to 2 Lexus dealerships to have this issue sorted out, I believe they cleaned some of the weather stripping and I never had this issue, moving forward. There was leaking from the right side above where the amplifier is located which I believe leads to this failure

 

Shoot I figured, ima check the scrap yards or junk hards if nothing guess ill have to shell out the money

 

If I remember correctly, there was someone on the forum who offered a service in fixing these boards, I'm afraid I don't remember his username but if you search, maybe you can find it. But yeah, there's a bunch of totaled IS's, shouldn't be a difficult find, try to negotiate the price with these sellers

 

There was a thread around here somewhere where someone cleaned off the corrosion and it started working again. Worth looking into. Otherwise there is a guy that repairs them for $350ish on eBay.
