Trash picked 32" LG TV hack & audio amp experiments

This TV came from the local recycling center, where it was sitting sad and abandoned in an E-waste container with a broken mainboard.

The cause of failure on this TV is likely thermal expansion of the solder joints of one of the big BGA chips; since they have big, heavy heat sinks mounted on top of them, the load on their solder joints is considerable.

    +FFcossag Try entering the service menu. I don’t have that TV but looking on another youtube video it seems like there are options to enable EQ and Bass EQ

    Made in Poland? KURWA, that’s unexpected!
    By the way: I can’t even use the headphone output of my Samsung TV – an 60s Tapedeck may have a better noise level than this thing.
    Luckily there is an optical out.

    Thats cool and all, but how do you just use the power board and audio/display board to power the sound bar? Say like if you were using them as an amp for the soundbar to use it with another tv.

    My TV has an annoying issue. The headphone jack output volume can only be controlled from deep in the menu. You can have the TV speakers running at the same time as the headphone, which is just a dumb idea. It is cheap junk though.

    1:12 that is a PIECE OF SHIT my dad has one from 2008, and it works LIKE NEW.

    Haha great video!! Those cushions look comfy, how come they are US flag not Swedish flag!? Would the same board be used for different sized TVs and what about the TV headphone socket? Would that have the same problem as the amplifier chip??

    15:10 Breddy gud gushions 5/5 :DDDDD *clap clap clap*

    are you from italy?

  17. DAVID GREGORY KERR on March 20, 2022 at 12:14 pm

    There is a TOSLINK optical output so can’t you not use that?

    I’d expect the angle the TV is sitting on will in turn help keep the BGAs from cracking off from the weight on their backs of the heatsinks, aside from the snot you used to reinforce them. did the chips even have the glue spats on the corners from possible wave soldering? sheesh. (I will admittedly say I once permafixed a D830 with a good-month NVS135M that had cracked joints by giving it gobs of superglue underneath after it was nice and cooled down… but this doesn’t always work, seems.)

    I did a similar mod with my HP F1703, after fixing the display connector which had cracked joints from the factory, probably why it was inevitably thrown out and there were lawsuits about the model. mine was a bit… easier, though. the monitor provides passthrough voltage from the 12v wart that powers it to also power some shoddy HP-rebranded speakers and maybe a subwoofer if you had money for it, back in the day. this is done through a smaller DC jack next to the main one. the idea was the power brick was over-spec for the monitor so it could drive those:

    what I did was removed that jack and replaced it with a normal one. originally it ran a WRT54G in my bedroom way back about 7 years ago, and then I stopped using that so it went unused. when I killed my 2007FP a few months ago, I quickly grabbed it from storage and put it in place, moved monitors around, and now it powers the Dell sound bar (used mostly just for headphones because they’re horrible otherwise) on the 21" Dell panel on the left. does this through a 12v 5A supply I was originally going to use with the SGI 1600SW on the shelf behind me (ample breathing room for powering both the monitor and the SGI multi-link adapter I can’t get my hands on at all for cheaper than $100), and is still absolutely over-spec even with two loads hooked to it.

    and no, unless the speaker bar turns on with the TV, you’re still going to have to leave your bed unless you mod a broom handle with a capacitive pen tip…!
