"No picture, no sound, no backlight LG 47 LW5600" için yanıtIf the power light blinks 2 or 3 times, you may need to reflow the CPU chip. Details at https://lab.remaker.com/2020/11/lg-47lw5600-power-light-blinks-red-3.html, and also on other iFixit posts about the 47LW5600.
"LG 47LW5600, No backlight, no sound, no picture but it turns on..." için yanıtI had the same problem, wrote it up in detail at https://lab.remaker.com/2020/11/lg-47lw5600-power-light-blinks-red-3.html This is apparently common with the 47LW5600, 65LW6500, 55LW5700, 55LW5600, and 47LW5700, which share the same mainboard (EBT61438207 / EAX63969204). These systems have a silver BGA chip living under a big heatsink called the XD Engine. Like a lot of BGA parts on consumer equipment (GPU, Xbox, etc), they eventually lose connection to the underlying board. A local shop would pull it off and reball it for $70. Lots of places on eBay also offer that service. So I thought I might try to reflow the chip. (1) Remove the big heatsink. Use needle-nosed pliers on the tabs each of the 4 pins from bottom side of the board: gently squeeze the tabs and pull the pin from the top side of the board. They have springs on them. Once the heatsink is off, you will see a silver chip with the LG XD logo on it. (1) Lay a piece of aluminum foil on the board, but a hole to expose the chip. If you press the foil...
"Turrns on blinks 3x and turns off" için yanıtI had a problem on a similar model. The mainboard needed a solder reflow, specifically, the XD CPU chip under the big heatsink. I wrote up the process in detail at https://lab.remaker.com/2020/11/lg-47lw5600-power-light-blinks-red-3.html, but it’s the same as any BGA reflow: Remove the heatsink to expose the troublesome chip, optionally add flux, shield the surrounding area with foil, heat the bottom, and use an oven reflow of your choice. I used a cheap heatgun, with the 550 F setting (low), heating the underside of the board for a little over a minute, and then heating the top side for four minutes, with the heatgun always moving in small circles. You can also take the board to a repair shop to get the chip professionally removed and re-balled. eBay has a number of services that will do this by mail.

The drive that works depends on the exact model of time capsule. The A1302 takes a 10TB drive but the A1355 does not - I don’t know anything about the A1409 - I mistakenly thought they were identical when I wrote this answer.
