Hi is any one can help me on getting the Schematics for Magnavox MDR515H/F7 And Magnavox MDR537H/F7 PDF file thank you I really appreciate it. Just need to change some component on
the main board and the power supply board. I looked all over for the internet and I cannot find the Schematics sheet for both of them. I don't know where else to look I hope someone can help me...03-07-2025, 01:03 PM -
Dear Badcaps forum members,
Hope that you are all well!
I am a newbie on a mission to figure out the cause of the PSU making a "chirping" noise:
Having searched for this symptom online I have found some indication that failed capacitors may be an issue. To help with the troubleshooting, I have tried to isolate the problem and disconnected the PSU from the rest of the device - the chirping remained.
I have then found that the whole PSU (apart from a small add-on board) can be replaced, and there is even a datasheet for it: https://cdn.badc... -
Hi to all 😎
I'm looking for any useful information to repair this interface (I have attached the image).
On this board I read E3215-1215A_4D.
This is the small plate inside the HD enclosure that allows to connect a 12 volt power supply, interface the disk with a USB 3.0 socket and is connected to the HD with the SATA connector.
If any of you have found a burnt or short-circuited component in a circuit like mine​, if you have useful diagrams for the repair, or even better a description for the tests at the test points, I would be very grateful.
in particular...11-12-2024, 08:08 PM -
I have been wanting to do this project for some time using a Mean-well switching power supply that I bought at least ten of them that were originally in a device that was abandoned for some reason they were listed new but removed from equipment that was never used
I do not understand Mean-well the capacitor next to the voltage reference ic chip was a brand that is known for failure over time the other capacitors are brand name needless to say it got replaced before I even powered it on for the first time
I used a four USB outlet and electrical plate that is made for... -
Here is the page of capacitors that I can choose from what is a good choice for a FSP 400-60GLC

I try to use a 565-1664-ND which is a 10mm in diameter unfortunately it will not fit because there are two of them the same size and value and there is no room and they go to two different circuits not in parallel...
