Unfortunately, the DVD player, along with other technical innovations, is prone to malfunctions and breakdowns. This circumstance, naturally, upsets the owner of this technique. But the situation is not hopeless, because the dvd player can be repaired.
Necessary
dvd player, screwdrivers
Instructions
Step 1
Carry out diagnostics to determine what is the cause of the breakdown. According to experts, diagnosing a DVD player is not such an easy thing. This is due to the fact that these technical means have a complex testing system that allows you to independently diagnose the player for its malfunction.
Step 2
Having determined the cause of the breakdown, open the dvd player, unscrew all the screws with a screwdriver and remove the top cover. Then unscrew the disc holder bracket, which is secured with two screws.
Step 3
Check your disassembled dvd player for any foreign objects that might prevent the carriage from moving. If there are none, connect the dvd-player to the mains and press the "OPEN / CLOUSE" button: the carriage should move to the beginning, the tray will be in its working position, and the spindle motor will perform several revolutions.
Step 4
If the laser does not light up or its glow is too weak, check the cleanliness of the lens. To remove dust deposited on the lens, use a Q-tip moistened with water: touch the Q-tip to the lens surface and wipe the surface with gentle circular motions (from the center to the edge of the lens).
Step 5
Check the laser supply voltage as well as the node where it is generated. If no voltage is present when the disc is loaded, replace U301.
Step 6
Check how well the protective jumpers are wired.
