SO-8 25u/25q one. Don't get me wrong. I've been fighting those windmills for quite a while and found that out the hard way. That flash contains nothing but key layout (vol+/- bt) and custom startup/shutdown audio. Software, brandless, runs inside otp/mask CSR chip.... -
Why would you try reading stm32 flash? It is well documented you can't do that. SWD is a serial JTAG yet well documented. Talking about CSR boomboxes: take a working set, desolder spi flash and give it a crank... yep..it worksLeave a comment:

Re: Hisense 50P6
a working panel to scrap?
the first post seems like a VGH/VON (brand dependent dubbing) issue. You can't just swap T-CON boards when ribbons match....Leave a comment:

[QUOTE=howardc64;1221091] just fuses? /QUOTE]
No idea tbh. Guess LG put them for "debugging" purpose. It takes cutting on other manufacturers panels.Re: LG 43UK6500AUA no LCD image, backlight and sound okay

There are five 0 ohm resistors on both sides of the panel dubbed CL-1 through CL-5. Try removing them all one side first (I shift them with two soldering irons) on the left-hand side first (observe results) then do the other side. Both ribbons t-con->panel should be connected. There will be no image if one of the t-con<->panel ribbons are disconnected.Last edited by b0ba; 03-16-2023, 03:18 PM.Leave a comment:
