The power supply alone can be rather hard to troubleshoot, and that’s not all unfortunately. One also has to deal with other major sections including the decoder and the loader.
Anyway, to make things a little easier for you, here are several DVD player repair tips that you can make use of pretty much immediately.
Fixing DVD player problems can be a lot less stressful if you have some kind of reference material that offers helpful images of a DVD player’s 3 primary sections: The power board which houses the switch mode power supply, the decoder, and the loader.
It’s imperative that you gain a good grasp of how these sections operate so you can quickly identify problematic symptoms, isolate them, and finally, proceed with the restoration process. And the best way to learn is by referencing manuals that are jammed with helpful images and illustrations.
Basically, if you’re new to the concept of repairing DVD players, then I suggest you refrain from using a reference book or manual that contains only text. For your info, there’s a very helpful illustrated DVD player repairing pdf which is available via this website: http://howtofixadvdplayerepairguide.info/
Prepare The Right Tools:
If you’re serious about troubleshooting and repairing DVD players like a true pro, then you’re going to need a digital multimeter for various testing purposes. Now, are you interested in using only one hand when performing voltage testing on the primary side of a DVD player’s power supply? Okay, that’s absolutely doable, but you have to attach a crocodile clip to the meter’s negative probe. This simple modification will allow you to do that voltage test with just one hand, and I must say, this approach feels a lot more comfortable!
One more tool that I believe you should have on your workbench is an isolation transformer. You’re going to need this tool when it comes to safety. You see, troubleshooting a DVD player’s switch mode power supply can be dangerous as you’re completely exposed to the risk of electrical shock. However, with an isolation transformer at your disposal, the risk of getting electrocuted is greatly minimized.
One of the best DVD player repair tips I can offer you right now is this: initiate the proper safety measures beforehand. One of the safety measures is to use an isolation transformer which I mentioned above. Another is to refrain from staring at the DVD player’s laser beam when the unit is switched on during servicing. Keep staring at the beam and you will most likely damage your eyes!
Some more good safety measures include putting on rubber shoes or sneakers to prevent electrical shock, utilizing only plastic screwdrivers for the purpose of shock protection in the midst of servicing a non-operational DVD player, and switching the device off and unplugging it from power outlet, that is if you aren’t doing voltage testing.
If you’re planning on doing voltage testing, then yes turn on the equipment, proceed with the testing in a very careful manner, and then switch if off. These safety measures must be followed, otherwise you may get jolted while troubleshooting and fixing DVD player problems.
Power Supply Voltage Testing:
Performing voltage test on a DVD player power supply is pretty straightforward. If you wish to test the primary side, just remember to make use of the main capacitor’s negative pin as the ground. With the secondary side on the other hand, you should utilize the ground pin situated on the connector output. And you want to keep in mind that the primary side of a DVD player’s power supply contains opto-isolator with two legs, and another two located on the secondary side.
