Question about Televison & Video

2 Answers

I have a Pioneer SD P4573. Recently it powered down after approx 5 seconds on. I reset the surge protector and it came back to life and remained operational until I turned it off. The next day, the same thing occured except for that it would not remain operational. It continues to power down after approx 5 seconds from each reset. If I do not unplug the TV cord or reset the surge protector, it will not come back on either via remote control or manual ON/OFF switch. I've unplugged the set for an extended period of time (3 hours) to no avail. Besides treating it like a horse with a broken leg are their any ideas out there?

    My Pioneer sd-P4573 will not turn on at all

  • lpandbecky Sep 07, 2009

    Follow -up: I tried again with the unplugging solution. This time I manually powered on and shut down the set a few times manually. Then I powered it up and held my breath to see what would happen. Viola, it stayed on and ran fine. Good thing as I was running out of breath. For over a year it ran fine until it did it again. Unplugging and plugging back in and on-off-on-off a few more times and now she runs. Recently I read somewhere a capacitor from my power supply board may need replacing or replace the entire board. If that is my dilemma, then the on-off stuff should just be a placebo for my own peace of mind. But when I didn't do it, it would power back down. If I could just replace a bad capacitor then that would be fine but replacing the power supply board(s) is beyond economical means in my opinion. It hasn't reoccured in quite some time so I'm waiting it out.

When I turn on my Sony TV, ti stays on about 30 seconds then shuts off, What do you think is wrong?


Do a Power Reset.
1. Turn off TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If issue persists after doing the steps, reset the TV to factory default settings.
1. Turn on the TV.
2. Using the supplied remote, press and hold the UP arrow button.
3. While holding the UP arrow button press the POWER button on the TV itself.
4. When the TV goes off, release the POWER and UP arrow button.
5. The TV will turn on by itself and the initial setup screen will be displayed. Just follow the on-screen prompts to finish the setup.

Do a Power Reset.

2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

No picture or sound?? status light flashes in four blinking intervals. I was told it could possibly be the lamp it has never been replaced.


The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

Hi, if this TV was hit by the surge and it was protected by a surge protector, please follow this reset procedure.

If the problem is still there and the light is still blinking 4 times, this means that the surge has destroyed the Vertical deflection component. in this case, it will have to be replaced.

please rate and have a great day.

When i power up the tv, it immediately shuts off


How old is the tv? Sounds like the bulb. Is there any kind of lamp light indicator blinking or on? Averager life of a bulb is a few years, but could very well be shortened. Also check any surge protectors you might have. Maybe you recently had a surge and it needs to be reset. Last but not least try recycling the power on the tv. Unplug for 10 seconds then plug back in. happens a lot with cable boxes, recievers, and tv's from time to time.

TV Zoom mode


Change the batteries on the remote, point the remote at the Sony, and hold in the power button for 5-7 seconds. Then depress and re-press the power button - see if you can get the tv remote to respond again.

Then, always try the quick reset:
