Ok guys, this radio was in my boat when purchased, loved it but after about a year it started randomly scanning through the menus and would stop playing intermittently until it died altogether. I bought a new one, have had it for 3 years without a issue, until a rushed battery reconfiguration (there's 5) had one of the amps get both positive and negative connected to the hot and it let the smoke out while burning a hole through the board. Thinking the old radios issue was in the faceplate, I swapped boards and in my drive it worked. I launched and made it a mile before it started scanning again and then quit. Once home, it came back on but will start scanning after a few minutes, but won't stop playing music. I've looked everywhere online for a electric schematic of the board but nothing. I still have the other one that has everything still good, just that one particular hole. Any ideas what is the culprit? I really don't want to dump another 500+ on a new one.. Again. Thanks

Ive got this stereo open at the moment and the small 12v fan won’t run. I’ve tested it by itself with a Bench PS and it’s working ,just not when plugged into the board when the stereo is switched on.
Any help is welcome.
Cheers.! 🙂

The PCB motor for 1987 Technics SLP-120 CD player has slow spin-up issues. Similar to what another tech in the below video reported.

I replaced the three bi-polar 47uF electros but that made no difference. The orig three bi-polar 47uF electros tested okay on my ESR M-tester.
I have not tested/replaced those alum. SMD electro PCB caps.
Are Al smd caps are more prone to failure (or degradation) than regular thru-hole electros?

Hi!
I tried to desolder through I had IC that I wanted to replace but failed. And now I came here to learn what's the correct way for doing this. I tried to use soldering wick but the capillary force kept solder in the hole. With soldering wick I only managed to remove the part of solder that was outside the hole. But the solder that was inside the hole never got out. And of course when I moved on to next pin the solder in previous hole hardened again so no matter how many times I did all the pins there was still solder in holes.
Question 1: what would have been correct... -
Well, I will be the first to admit that I screwed up...
In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.
I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.
I have 2 that I have found and have in my possession. ... -
