OK, that cap is not on the board at SJ either.

Yeah. You scared me when you posted that for a second til I looked at some others. I thought I was slipping.

Got a replacement board in and this time it powers on just fine, goes to Akai logo just fine, even shows dvd drive fine and says loading, but after about 2-3 seconds the screen goes off, and then standby light. It then powers itself back on after about 5 sec and does the same thing again. This is with the original PSU that is working perfectly fine.

After checking voltage, PSU reads 24 up to the point where screen powers off. When the screen goes off followed by red light, its drops to 17 and then back to 24. On the mainboard, it always reads about 21 until the screen goes off then it drops to 12 then back to 21

Hey good timing I just cracked open an LCT3201ADC last night. Manufacture date October 2006. Maybe I can be of help. If you need photos/measurements or anything let me know while I still have it apart.

This one has problems with one dead speaker and the other cutting out at high volume but otherwise working okay. Very visible bad caps in the audio circuit on the mainboard and a bad bunch in the power supply secondary. I'm guessing replacing those should clear it up but I'll take some voltage measurements for a before & after.

I was told that maybe it had been repaired once before. I noticed that all caps everywhere are CAPXON, except the few bulged ones on the mainboard audio are DECON. I see lots of different looking caps in your photos.
