Today I got a Samsung HT-TZ315 dvd player who has a problem of loading the dvd. This means, if I wish to play a dvd then it shows only loading on the front lcd but the dvd will never loaded and the music or movie will never start playing.

This is the picture without the cover.

Are you realizing what is happening?

The lcd shows “LOADING” but the disk is not rotating. For some reason the motor that rotate the dvd didn’t turn on. The problem could be:

– bad contact, broken pcb, flat cable etc.

– some bad components

– bad driver ic

– bad motor

– firmware problem

This is the list how I will do my checking and repairing continuity. Let’s go and repair this little monster.

This is the overview of the dvd player. The dvd mechanism is connected with 3 flat cables. On the picture above, I labeled the cables with numbers from 1 to 3.

  1. cable to the laser optic
  2. cable for the laser optic motor, dvd rotary motor and the tray switch
  3. cable for the tray open/close motor

All this cables has to be disconnected and the four bolts have to be removed to take out the dvd mechanism safely. For first, I checked the cable and connector under the number 2.

When I gently flipped the connector, I felt that the contacts gently moved on the legs 1 and 2. That’s the legs for the motor that rotate the dvd.

Just in case, I checked the entire path from the connector to the AM5766 driver IC. In some case when connector this type have a bad soldering joint it could be does the wiring under the legs are broken, or another wiring next to the bad soldered leg are broken.

This is the AM5766 driver IC how it is wired on this model of dvd player.
After the test I resoldered the contact and reassembled the unit to se did, I solved the problem. The result was positive, the dvd started to spinning and the movie started playing and no more loading forever on display.

    Thanks Chris for a well written article. You have provided excellent pictures, diagrams with clear arrows and a good explanation. I have had a few DVD players in for repair, but non with a fault like this. I will keep this in mind for next time.

    Well done Chris. Good that you also were able to find the Samsung schematics for this HT-TZ315 dvd player repair. Because that is in most cases not possible. Do you therefore also have a link were you found it? Thanks for the already given diagrams!

    Thanks for supporting Albert, of course here is the link from where I downloaded the schematic of that dvd player.:
    http://elektrotanya.com/samsung_ht-tz315.pdf/download.html

    Pleas look in the down area of the page for this text:
    "This file is downloadable free of charge: ...processing...
    (You are not logged in, only 2 downloads per day possible for you.)"

    and wait till the processing is gone and it's written "Get Manual" then click
    on "Get Manual" and you can download the manual.

    It is a bit hard to download from this site if you are a first time visitor on it.

    My best regards.

      Thanks Chris. Indeed downloading often can't be done succesfully on that site the first time. It seems to have a bad server or something like that. But when you are a registered user on ElektroTanya like I am (it's free after answering a few simple Electronics questions), you are not limited to only 2 downloads a day. And even if the first 2 download tries fail you then also can try downloading a few times more the same day. (Until the download succeeded). But keep in mind to log in on that site every once a while, else you loose your registration privileges. Cheers!

      Frans: are you checked does the disc is spinning until the loading is in progress?
      What would happen if you let the dvd load a while?
      Will be some error message or would the loading process last forever?
      What is the whole product number and/or type of that Sony dvd?
      My best regards.
