What’s rule number one? Okay the first rule is to get your basic safety procedures in place. Some electronic repairers tend to take safety for granted and I think that’s very unprofessional, and not to mention dangerous! Basically, before you start troubleshooting a faulty DVD player or its switch mode power supply, you want to make sure you’re feeling fresh and wide awake.
If you’re feeling a little fatigued, then stop what you’re doing and get some rest first. And don’t forget to buy an isolation transformer which provides security from electrical jolt. This tool is so important, especially when you’re attempting to troubleshoot a DVD player’s power supply.
Also I would recommend you purchase a low-cost, yet highly detailed DVD player repairing solution manual. You can get download details for a clear and easy to understand manual by visiting this site: http://howtofixadvdplayerepairguide.info/
One more basic safety tip I should mention is that you must keep your eyes away from the laser of the lens. Direct exposure to this component may result in serious harm to your eyes. Okay, so we’ve established rule number one, now let’s take a look at a few solutions for repairing DVD players.
Perhaps a fuse in the DVD player’s switch mode power supply is completely smoked, therefore causing the player to stop working altogether. If you think this is the problem, then you should do a small test to ascertain whether the fuse is the cause of failure. Grab your meter and set it to low ohm resistance.
Do this correctly and then listen carefully. What do you hear? Do you hear a buzzing sound, or do you actually see a reading on the meter? For your info, the buzzing sound or the presence of reading indicates that the fuse is working fine. No buzzing or reading means the issue definitely lies with the fuse.
Chopper Transformer Test
Sometimes the power supply ceases to work as a result of the primary coil being open. So how do you find out if this is the source of the problem? That’s a piece of cake! Once again, grab your meter and use the low ohm range to see if there’s a reading. This is pretty much the basic approach on how to fix a DVD player power supply – testing the components within using the proper ohm range.
But what about a primary coil that has been shorted? Can we use the same approach for testing? Unfortunately, the answer for this particular issue is no…Instead, you’re going to need a fly back tester in order to test a shorted primary coil.
Power Board Scanning
When examining the DVD player’s power board, you should train your eyes to scan both sides for any signs of abnormalities. Keep your eyes totally focus on both areas as well as the components. This careful approach would help you identify damaging signs such as burnt components or capacitors that are bulged, after which you can make the necessary replacements.
DVD Player Troubleshooting No Disc
Believe it or not, the vast majority of cases involving “No Disc” problem is due to the DVD player’s spindle motor. Each week, I get many customers sending in their no disc error DVD players to my shop, and they are extremely frustrated about this particular complication. As I said, the source of frustration in most cases is the spindle motor which is responsible for spinning the disc.
So when it comes to DVD player troubleshooting no disc, what you should do is perform a simple test on the spindle motor. Your meter once again set to low ohm range, and find out whether the spindle motor’s reading is optimal. By the way, you can even use an analogue meter to test the spindle motor.
