I could not open up the special surface mount ferrite core used for the inductor as it was cemented together and not being able to obtain a suitable replacement core I made a rather drastic modification as a "work around" for the problem. The circuit is robust in that if an overload occurs the LTC1771 will limit the peak current and the ON time duration and this is what was happening with my unit. The specialty switched mode power supply IC is a LTC1771 device which is essentially designed for "current mode" of operation with a second voltage feedback loop. The internal power supply uses a series and shunt P channel and N Channel MOSFET transistors respectively, to obtain a stablised +4.8VDC and -4.3VDC power rails. Once heated up it would continue to work correctly until powered OFF and left to cool down whereupon it would fail to start up again. The fault turned out to be a shorted turn on the internal switched mode power supply series 220uH inductor that would go away once it was heated gently. The fault symptoms are: The internal RED SPDIF optical digital audio output LED is lit but the power, CMSS and audio mute LEDS are all OFF and the unit is not working.

If your desktop or laptop is running slow, or keeps crashing or hanging, there is a good chance that updating your drivers will fix the problem.Įnsures your hardware runs at peak performance.įixes bugs so your system will have fewer crashes. Many computer problems are caused by missing or outdated device drivers, especially in Windows 11. Next, update individual drivers or all of the necessary drivers with one click. When the scan is complete, the driver update utility will display a results page showing which drivers are missing or out-of-date: Once you download and run the utility, it will scan for out-of-date or missing drivers: It will Update all of your drivers in just a few clicks, and even backup your drivers before making any changes. The Driver Update Utility automatically finds, downloads and installs the right driver for your hardware and operating system. Automatic updates could save you hours of time. If you are having trouble finding the right driver, stop searching and fix driver problems faster with the Automatic Driver Update Utility. Many device drivers are not updated through the Microsoft Windows Update service. Visit our Driver Support Page for helpful step-by-step videos Install Drivers Automatically In most cases, you will need to reboot your computer in order for the driver update to take effect. Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.Ĭlick the Update Driver button and follow the instructions.
