We connect to the player from Vogue headphones and volume control
Universal hysteria swept over the fact that the magazine «Vogue» contains free video player. Magazines in Moscow sweep piles. And I succumbed to the general hysteria and bought this miracle. Having played, I realized that if you use it as a video player, you need headphones, and it would not be bad to make a volume control.

Many in the post tried to solder the second speaker, for which seemingly exist contact pads, but were disappointed by the lack of sound. A cursory examination shows that for the second channel there are also contact pads for the amplifier. Initially, the idea was to take an amplifier chip and the rest of the distribution from another board and solder it. But having carefully considered the board, I realized that other platforms are designed for sealing the headphone jack. What does this connector go tracks from the processor bypassing the amplifier. I decided to check and soldered to it a headphone jack, uprooted from the old player. And I guessed it - both channels work in stereo mode!
Connected headphones
Now everything, at least you can already give up the wheezing dynamics, and listen to normal stereo in normal ears. Now you can bite the speaker
Bite the wire going to the speaker
Special economists of battery energy can completely dismantle the microcircuit of the amplifier with the distribution, but it seems to me in comparison with the power consumption of the display, it is such a trifle that it is not worthy of our attention.
Of course, headphones are wonderful, but I want to regulate the sound. Poking a screwdriver into the board showed that the platforms in the middle of the board are nothing more than a volume control! What does the left pair, with the closure, lowers the volume, and the right increases. Therefore, we put the buttons on the wires and we will be happy. I want to note that the central two contacts are just earth, it is not necessary to pull each one separately. I just soldered two buttons together and brought the ground to the place of the spike.
Soldered wires. With pinout.
Total result was as follows:
Collected paper player
I decided not to lose the “paper” style of the player, and glued the hot-glue buttons on the pad. Now you can calmly look at night, without interfering with anyone in the desired volume to watch the next series of your favorite series.
