Question about Panasonic VIERA TC-P50U50 50-Inch 1080p Full HD Plasma TV

1 Answer

TV shuts off after 3 seconds

The PVR seems to be working correctly. After an overnight rest, the TV switches on with the remote power button. A perfect picture appears, but the screen goes black after three seconds and clicking sound is audible in the set

SOURCE: I just bought a Panasonic SA-PT480, set it up,

I can't find a manual for this thing, which I believe is part of the SC-PT480 package.

I'd plug it straight into a wall outlet for further fault isolation and treat it like it has never worked, no assumptions.

Surge protectors only address outside power surges. Overheating, speaker shorts yada yada can still happen. Effective self-protection circuitry activation need not be preceded by smoke and light shows.

When the audio cut off did the unit also die, or did it look otherwise alive? If the former...

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections as a root cause for intermittent shutdown.


Maybe a sleep timer clicked it off. Or if it seems to power on but remains silent some other setting like muting, tape monitor got activated. Or the source audio died. Lots of things.

Refer to your dealer about this situation, hence there is no problem with your remote control. If some buttons are working others not, then the remote could be different. On the manual, there is a model number for the remote, if it does not match with the model number on remote, then change it.

I think the problem lies with what input you have selected on your tv. On your (tv) remote control there should be either a circle or square with an arrow on through it. With your pvr already switched on, turn your tv off then on again. When it says no signal, press the button on your tv remote I've described until you see a picture.

Sounds like one of the front panel buttons is jammed. press each one and see if any fail to "rebound" or feel different from the rest. You can usually work the button in a 'circular motion" to release it. If the buttons seem normal , it's possible that the switch inside the TV has collapsed

PVR locked in Standby with LED Display ''STARTING'' otherwise dead


pvr's generally just record to a hard drive if you are lucky you may be able to remove the drive and connect it to a computer and retrieve your videos (format permissive of course).

The fact that it hangs on starting suggests that perhaps it has failed to initialize software on the device.

if you are lucky there may be a way to reload the factory firmware onto the device but i am yet to see one that has been done with success.

Trouble switching on my Sagem 6200T PVR.


Hi margaretanne on Dec 02, 2008

I have a similar problem with mine. I find the battteries are loose, I remove the back of the remote, jiggle the batteries and press the button, and it works, until I drop the remote and the batteries loosen again.

Intermittently Working Correctly with DirecTv


Update your Harmony remote control software on your PC to the latest. Go into the TV device settings. The software should recognize if there is an update to your TV's IR commands. Try the same things with the DVR.

It's also possible the TV and/or DVR are locking up due to IR commands that are being sent too quickly. The remote has a setting for the delay between commands sent to the same device as well as the delay between commands sent to different devices. Try adjusting these settings:
  1. In the Harmony remote software on your PC, click the "Devices" tab.
  2. For the "TV" device, click the "Settings" button.
  3. Click the dot next to "Adjust the delays" and click Next.
  4. Adjust the "Inter-key" and "Inter-device" delays to something higher and click Next.
  5. Follow the steps to save the changes.
  6. Repeat steps 2-5 for your DVR device as well.
