I've seen many different projects here.
I want to show something different now.
A few months ago a friend gave me LCD TV with a broken display.
I disassembled it and remove the panel.
Do you think is possible to use these parts for some custom project?

I found user manual and met with basic functions and technical specification.

TV has a digital stereo amplifier 2 x 8 watts, 8 ohms. Line input, USB input.

I connected CD player to the line input and sound was good,
but no bass, TV has small speakers.

I connect USB flash drive with music files.
According to the user manual, press the button "HOME", then choose USB and choose file.
All this becomes easier when you have a screen to watch where navigate.
When no screen, you need to find the right combination of buttons to reach the first recorded file and play it.
I started doing experiments with various combinations for three hours, but without success.
I was desperate and I gave a break.
After a while I kept trying and I was lucky - I was able to play the file without using a screen.
I wrote the key combination and then I remembered.

Now I can use an audio amplifier of broken TV to listen to music from a line input or USB memory.
To be continued... ;-)

Here's what's under the back cover - 2 large boards and 2 small speakers:

The speakers are 8 watts, 8 ohms.
I decided to test with other bigger and better speakers.
I chose these 230 watts, 4 ohms.

I also need a box to put them in. I found one from a laptop.

Here is the first test with the new speakers:

In theory, when decreasing from 8 to 4 ohms,
the power of 8 watts should be doubled - 16 watts per channel.
In fact, I am quite pleased with the sound of these speakers.
They have good bass, good mid and high frequencies.

To be continued... ;-)

Those are not cheap speakers. You'll probably blow the amp running high current. I have thought about doing this with an old iPhone dock but generally speaking it easier and cheaper to buy a new one with all the same features. I picked up a cheap teac freestyler and it rocks my work desk.

Thanks for interest, guys.

I dismounted the boards from the TV,

attached them to one base, and attach it inside the box.

I mount the remote sensor, control buttons, line input, USB input, power supply.

Now my music box is almost ready.

I did the tests a few days - I listen for 3-4 hours, the volume is about 40-50%.
It plays well and there are no problems, heating is very minimal.
I leave the top cover open and this improves cooling.

To be continued...

OK, I thought you were going to use the rear case of the TV and make a front panel  :hmmm:

OK, I thought you were going to use the rear case of the TV and make a front panel  :hmmm:

I had such an idea, but I gave up.
The box be large and heavy and I need boards and other details.
I was inspired by cardboard boxes - Berlin boombox.

 

Here are some additional pictures and information about the project:

In the big box have a smaller box with a handle.
It's ideal for all necessary accessories:
Power cord, remote control, usb memories, a short user guide, and more.

The last picture show a completed music box.
For more effective, I glue pictures with boomboxes from catalogs.

Pros and cons of the project:
+ Light weight - about 2-3 kg.
+ Easy to use.
+ Good sound.
+ Cheap.
  (I bought the speakers  with vouchers, and all the other parts were available)

- works only on AC electricity.
- is managed only by remote control.
- there is no information about the files being playback.
   This problem I solved by making a paper list of files stored on the USB memory.
   For easier navigation, I've recorded mostly mixes, or album as a single file.

In use, leave the top cover open and this improve cooling:
This hole also serves as a bass hole.
Here's a short demo video:
(True sound is much better than that,
but my camera does not record the sound perfectly)

Yes, this project was experiment and fun. :yes:
Experiment, because I did not know what would happen...
Fun, because the work was enjoyable...
Now I have a music box, unique and different than anything conventional. :breakdance:

When I was filming this video last week,

the box was only half covered, but now it's finished as the last picture.
This song is part of my mix of 80s. :dj:
