Hi Charles
The SMPS section circuit is a built in part of the main board. Just see the location. I've marked it. If you're in search for the SMPS circuit diagram, and you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
Search the site by type in the "brand name" of your device, in the "Search box at the top right of the Homepage" to get gathered related posts.
Circuit diagrams of SMPS section of many popular brand devices are given.
There will be a circuit protection system activating. You switch it and an overload condition develops so it turns off to prevent damage getting worse. The overload could be cause by faulty or touching speaker wires. Removing these might stop it. Another cause is faulty or shorted transistor or other device in the power amp section.
Fuses are incorporated in circuits for a good reason; to protect components and wiring in the event of a current overload.
If a lower rated fuse is installed in a circuit, it will blow under normal load conditions as it is rated for lower power usage.
If a higher rated fuse is used in a circuit, it would not blow before a overload causes damage to circuit components or causes a overheating condition and possibly a fire.
Therefore, it is essential that the correct fuse be used in the circuit it was designed for...
Your particular auto may have a fuse diagram in the owners manual, or printed iside the cover to the fuse panel - if not, ask a dealer for the correct fuse designation. The fuse diagram should show the size fuse needed for the seat controls.
IF the fuse you are blowing is the correct size, STOP using the seat controls until you have the problem troubleshooted by the dealer or a good mechanic.
Good Luck. JWM
There is a short circuit at the main board to your TV. Any component/s have been shorted, and the power supply section overloads; and the protection circuit energizes; shuts your TV OFF. That is happening now. Contact any service technician. The troubleshooting to this type of fault/s won't be an easy one for a user. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view. http://electronicshelponline.blogspot.com/
There should be a overload to its main power supply regulator section cirlcuit. Actually this section is working well, but when it supplies secondary voltages to the other section circuits, it detects an overload with any other of it, and shuts itself OFF, to prevent further damages, goes to standby mode, and then to protect stage.

Hello Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service. Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display. Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.
Hello Protection display will come over this type of set, when it is overloaded or system confused condition. Just unplug the device from AC mains socket and replug it after 4 to 5 minutes, and see whether it shows any protect display. If it shows it again, just disconnect the output loads, ie, connected speakers, and check. Again it displays 'protect', the internal circuit, especially the output amplifier circuits has the trouble, and the system need service. if it does not show protect display, after disconnecting the speakers from it, check the speakers or its connecting wires for damage. OK.
The chances are that it does so due to a faulty part. Often these protection circuits are to detect an overload in either the power supply or the main amp section. Sometimes it's due to a speaker wiring problem, cables that are not suppose to touch - touching. They sometimes reset when either the overload has gone or the wire touching has been corrected. This sounds like it might be too late, and now a semi-conductor (on the heatsink) is acting like a piece of wire! Tripping the circuit. If you get power to the unit (lights etc) then it's probably not the power supply section to blame.
My AVR 5600 has worked flawlessly for nearly 9 years!
Suddenly, when trying to play music (DVD or CD) through my LS32's (JBLPro), once I achieve higher volume, the receiver cuts off.... Using a Symetrex mixer, NO OVERLOAD light on the Denon, it simply cuts off!
Re-cut all the wire connectors... TV movies (5.1) work great at normal listening volumes.... but tonight, when cranking up music, the receiver simply cut off. Blinking light...
