Powers on in standby mode but shuts off when anything is pressed remote or manually? t-752 reciever

Try following the steps below.
Step 1
Press the power button once. If the TV does not turn on, observe the LED indicator, usually located on the TV's lower front panel. If the LED indicator turned off after you pressed the power button once, it is in standby mode. Press the power button once again to exit standby and turn on the TV.

Step 2
Observe the Standby light if the remote control will not work. If the Standby light stays on, the television is in Standby mode. Press the power button on the television, then try to use the remote.

Step 3
Turn the Energy Saving Switch off, then press the power button. The Energy Saving Switch is located on the rear or side panel on most Sony model TVs. Refer to your TV user manual for the exact location of the switch.

r_pettit,

I can definitely assist you with this. What button do you press when you turn off the TV? Have you tried pressing 'SAT' then the big red 'Power' button on the remote?

Hello,

The standby mode is a power saving feature. In this mode, a it does not shut down completely, just goes to low power state and so it consumes less power. When it resumes from the standby mode, full power is restored.. During the standby mode, if the power supply is disconnected or interrupted, data might be lost.

Hope this helps,

Lucas

It sounds like the output transistors may be putting this into protection mode causing the unit to shut down to avoid further faults. It will need to be serviced.

When you turn the MAIN off you are killing all power to the set---Some advice---If you Google the model number of this set with the word problem after it you should find what I have seen a lot in these sets: they develop bad solder connections on the power supply printed circuit board---usually the board is about 18 inches tall and 12 inches wide--A number of sites online offer to have you ship them the board and they will resolder it for you.
I have repaired about 12 of these with this problem in the last 2 years---The board has to be removed(there are quite a few plugs that need to be labeled and removed and lots of screws that secure the board in place.)

Maybe not a job for a do it yourself person but the soldering (if it is your problem) will take about 45 minutes(including removal and installing board back).

Like most modern sets this set uses lead free solder and it is soldered(the boards) in a wave or one step process---over time from heat and expansion some connections may crack or even break loose----I would look at the POWER SUPPLY board(follow the power cord as it goes right to it)

If you have any questions or need help please contact me here.

I do this here for free so if this information has helped you take a minute and give me a vote here.

Did you try this....

In the event of a power outage, the RV-8 will display a BROWN
OUT!! PRESS STANDBY message. To turn the unit on, use the
STANDBY button. For more information, see “POWER
MANAGEMENT” on page 3-3....

POWER MANAGEMENT ON, OFF

"Setup" >> "Power Management"

Opens the POWER MANAGEMENT menu, which is used to automatically
put the RV-8 into standby mode during brownouts.
When set to ON, the RV-8 detects low voltage levels or a momentary
loss of power and puts the device in standby mode. In the event of a
power brown out, the RV-8 will display a BROWN OUT!! PRESS
STANDBY message. To turn the unit back on, use the front panel
STANDYBY button.

When set to OFF, the RV-8 will attempt to function during a
momentary power loss, however software settings may become
corrupt and need to be reset.
When the RV-8 is in standby mode, pressing the button turns the
unit on and activates all zones that were active in the previous
operating session.

The RV-8 does not power on.
1. Make sure the rear-panel power switch is set to the | (“on”)
position.
2. Attempt to power on the RV-8 with the front-panel Standby
button and remote control On button.
3. Examine the power cord to ensure a good connection between
the rear-panel AC input connector and the wall outlet.
4. Check the electrical circuit and breaker.

Press the Standby/On button on the remote or on the receiver (right below the Yamaha logo) to stop the audio output and display. The RX-596 goes into a low power standby mode when not in use; this allows it to respond to the remote when you press the buttons. If you want the receiver's power use to go to zero, you need to unplug it from the outlet. (You could also use a switched surge protector and push the switch to off.)

See page 9 (page 11 in the PDF) in the manual for the details on the On/Standby switch. The manual is available here: http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000057561.pdf . The page is also available here: https://www.manualslib.com/manual/197512/Yamaha-Rx-596.html?page=11#manual .

I hope this helps.
