been asking for hours and still no response from ANYONE at OAI on whether the new update will integrate with the PeneTech RealFlesh Membrane Peripheral — makes me think this whole product announcement is a lot of smoke and mirrors.

Thanks for all the helpful advice, I really appreciate it! It looks like there are pretty cheap replacement boards I can just order. I’m sort of interested in at least figuring out what failed but will try to stay away from anything too crazy.

what do you think — will i succesfully fix the tv, damage it further, or hurt myself (or some combination of the three)? responses in the comments!

- it sends 5V and 13V DC to the logic board (not pictured) and something like 130V for the LED screen. Somehow the rectification is primarily on HOT side, but I’m a little unclear how you can send DC voltage across the transformers, though — i think i saw something about pulse width modulation?

- you see the big line dividing “HOT” from “COLD”? HOT is connected to wall power. COLD is electrically isolated from HOT with the power transferred across the two yellow-taped transformers. That means COLD isn’t grounded to earth ground, but to the metal TV chassis.

it’s a samsung led tv. i couldn’t find a service manual but i found the schematic for this board. a few random things i’ve learned:
- those big metal rectangles are heatsinks, attached to the transformers. they look like shelves inside, i guess to have more surface area to dissipate heat.

this is allll power supply for my busted tv. so complicated!
brown pcb with some huge electrolytic capacitors, transformers/inductors of various sizes, and rectangular aluminum heatsinks, and two prongs for ac wall power. it’s on a gray shag rug on top of my multimeter probes.

you know how guitar distortion was originally people playing through busted amps and deciding they liked the sound? has anyone ever done that for “MIDI input into a software effect with a too-small buffer size”?

Best post I saw about this was like “You can make fun of Linux users all you want but they can’t hear you because their sound cards aren’t working.” (i use arch btw)

Not crazy though if you think of a floating-point number as representing the interval of real numbers that round to that float. For a number that big with only 23 bits of precision, you actually don’t know sin(x) to any precision.
