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:

TV07 by ivosn

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



TV09 by ivosn

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



TV08 by ivosn

Here is the first test with the new speakers:



TV10 by ivosn


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,



TV11 by ivosn


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



TV12 by ivosn


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



TV13 by ivosn


TV14 by ivosn


TV15 by ivosn



TV16 by ivosn


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.

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:



TV18 by ivosn


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.



TV19 by ivosn



TV20 by ivosn



TV21 by ivosn


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



TV22 by ivosn


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:
