    Checked main PCB at the main power connection. Re-soldered to be sure with the same results.

How do i reset avr-1705 denon amp?


Before you reset, are you doing this because the amp went in to some sort of protection mode?

Resetting will allow the amp to redo the self diagnosis. But if the problem remains then the amp will shut down again. Resetting doesn't fix things like bad wiring or blown output transistors. So only reset once you are sure you've checked through the system for any problems.

As a safety measure, disconnect your speakers before doing the reset. If the amp goes in to protection again then it is an indication that there are either shorted speaker outputs inside the unit.

Unplug the unit from AC power for 30 minutes, and disconnect all of the speakers and other associated equipment. Upon plugging back in, press and hold the power button at the same time for 5-10 seconds to force a hard reset.

If the unit starts up normally start connecting the speakers one at a time (shutting the power down before connecting each one), until one of the speakers causes the receiver to shut down. This speaker is faulty and would need to be replaced.

If the unit does not power up with NO speakers connected, then it needs the output transistors replaced inside the unit. These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink. In this case, the unit is in need of service.

Lg plasma mt 42pz10


I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.

Panasonic Th37PE30 Viera plasma stopped working


here is a complete list of all codes for panasonic tv's rgeardless of model if its panasonic it is these codes

1 Blink SOS: This shutdown operation is usually caused by a lack of communication between the A and the D boards.
1 Blink SOS: This shutdown operation may be caused by the improper connection of a SS board connector to the panel.
2 Blinks SOS: Pin 87 of the MPU IC9003 monitors the 15V line. During normal operation, the transistors Q9053 and Q9054 output a high to pin 87. If the 15V line is missing or shorted, a low is provided to pin 87. As a result, the unit shuts down and the power LED blinks 2 times.
3 Blinks SOS: IC9807 is a 3.3V regulator located on the D board. Its output is monitored by IC9003. If the 3.3V is not present at pin 86, the MPU shuts down the unit. The power LED blinks 3 times.
5 Blinks SOS: Pin 85 of the MPU IC9003 monitors the 5V line. During normal operation, the transistors Q9051 and Q9052 output a high to pin 85. If the 5V line is missing or shorted, a low is provided to pin 85. As a result, the unit shuts down and the power LED blinks 5 times.
6 Blinks SOS: Pin 90 of the MPU IC9003 monitors the status of the SC board. During normal operation, the transistor Q6581 and IC6581 output a low to pin 90. If the SC board becomes defective, a high is provided to pin 90. As a result, the unit shuts down and the power LED blinks 6
6 Blinks SOS: 6 blinks of the power LED may also be obtained from pin 3 of IC9003, the DRV_RESET input. The D board provides the 5V source needed to power the C boards. On the C2 board, the 5V is routed back to the D board via connector C20/C10, C11/D31 causing pin 3 of IC9003 to be high. If 5V is not routed back to the D board, pin 3 of IC9003 goes low. The set goes into shutdown mode and the power LED emits 6 blinks.
7 Blinks SOS: Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.
8 Blinks SOS: Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.
10 Blinks SOS: The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.
10 Blinks SOS: The F_STB_15V of the P board, as well as the derived SUB5V and DT9V sources are monitored on the A board for excessive current. If a short circuit is developed in one of the supplied lines, pin 114 of IC1100 receives a high. The SUB5V and DT9V lines are also monitored for excessive voltage. When an over-voltage condition is detected, a high is also output to pin 114 of IC1100. The DT9V is provided to a DC/DC converter to create the BT30V for the tuner. If the BT30V becomes excessive, a high is output to pin 114 of IC1100. A high at pin 114 of IC1100 causes the unit to shutdown and the power LED to blink 10 times.

Immediate shut


Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
