You have a short in that circuit , you need a wiring diagram an a diagram that shows wiring harness routing an a volt - ohm meter to find the short ! Locating a shorted circuit can be a real problem sometimes even for a competent auto technician ! It would depend on what circuit it is ! You best bet would be to take to a ASE certified repair shop !

Sanyo tv model dp50747 keeps shutting off automatically

Short circuited PCB inside it. Any one printed circuit board will have short circuited component/s; in turn draws tremendous current during switch-On, and the short circuit protection circuit inside the TV activates, and shuts it down, is happening now. Contact any service technician, or authorized service centre for Panasonic. This is not a user repairable fault.
If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

I own a Aragon 4004 mkII. Recently the the banana plugs on the right speaker output touched bridging a contact. The amp had been turned on and left on for up to 10min with this short occuring. Now the...

Tough one. I repair these for a living. A number of possibilities exist. Likely output transistors are blown on the bad channel. Fuses are likely blown. If the fuses are BLACK inside, don't just put new fuses in, more damage WILL occur. This is a bit more than 'good with a soldering iron' will fix. You need to know how to test an output transistor. You need to look up the transistor type so you know what it is. A service manual will be a big help (I could not find one online.) If more than two outputs are gone on the one side, all should be changed, they are supposed to be MATCHED. Remove and replace all damaged outputs, or replace them all if two are blown. Find the driver transistors and check them for short circuits. After repair, start the amp on a dummy load of a 250watt light bulb to prevent destroying the amp if there is a problem. If you are unsure of any part of this, find an electronics technician to help.

Code po446

P0446 - Evaporative Emmission Control System Vent Control Circuit

Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.

Causes: A code P0446 could mean one or more of the following has happened:
* Faulty vent valve
* Open, short or excessive resistance on Vent valve control circuit
* Blockage of vent valve
* Bad PCM

Possible Solutions: With a P0446 OBD-II trouble code, here are some things to try:
* Replace Vent valve
* Repair open, short, or resistance problem in control circuit
* Repair open, or short, or resistance problem in power circuit
* Replace PCM

I hioe this helps to solve it.

Receiver turns off shortly after powered on & displays "PROTECT"

are any other devices sitting on top of this unit? if so it could be an overheat.

If you have pets make sure the wires are not chomped on this can cause a fault.

Also make sure you have nothing other than the factory default speakers hooked up to it.

here is what the users manual says
im going to sum it up for ya. if it says protect that means you have a short circuit please unplug the unit resolve the short circuit and plug back in....... here is the link To the users manual

once it is opened as a PDF document go to the search/ find area and type in "protect" and it will say the same thing.

somewhere you have a short your going to have to follow all the wiring again and look closely

Breaker keeps tripping

Hello. Here is what I think, not looking at the unit myself, I would start by checking the heaters, both of them, and the heating circuit for a short to ground through the water, here is a link to the manual,

and from page 34 on has the proper diagrams. An electrician should be able to handle a resistance check of this circuit, with a multimeter. If not you need a repair person that can, look in your phone book for Restaurant repair service.
The other thing I have seen with these, is the solenoid coils have shorted out, and cause intermittent problems, but these usually blow the main board, this would be evident by black scorching either on the front or back of the board.

Hope that helped, and thank you.
Ask me if you need more help.

Power supply

Hi have a nice day!
Check if new fuse is of same type that is needed ie 2A , 2,5A as manual says. dont put different.
If you put correct fuse and blows then there is a short circuit at power supply area or after it and your TV must take to a qualified repair shop.
If you are familiar with electronic repairs write me down make and model to look for a service manual available.
