Question about Philips 50P8341 50" Rear Projection Television

1 Answer

Wont' Hold settings for channels, tuners, sound, ect.

Unplugged TV while on vacation, returned to TV that will not hold programming when off. It takes 45 seconds to move up one channel and audio is irratic. It doesn't respond to the Menu Select commands quickly, the clock won't set and the Statis/Exit button finally will exit the programming feature. It has done this before, but after reprogramming several times it righted itself. The unit is right at 5years old, this time it's been 3 months and it's not showing improvement. I have left it unplugged, I have reprogrammed, blown the dust out, tried entering an access code (that worked the last time it did this). You can enter it but once the set is turned off, it reverts to no codes, channels, it does hold the tuner selection sometimes, other times it reverts to the antenna default.

Televison station won't scan


If you are receiving a "No Signal" error message, verify that:
  1. All of the cables physically connected to the TV and the input device are secure.
  2. The input device is turned on.
Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:
  1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
  2. If the TV input is not selected, press INPUT until the TV input mode is selected.
  3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
  4. Highlight Tuner Mode and select the correct option:
    • Antenna-over-the air signals from an antenna
    • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
  5. Select Auto Search or Auto Channel Scan. (This varies by model.)
  6. When the search reaches 100% complete, exit to the menu.
  7. Check the available channels:
    • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
    • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.
If this does not resolve the issue, power cycle the TV and then re-run the channel scan:
  1. Turn off the TV.
  2. Unplug the TV from the electrical outlet.
  3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
  4. Release the power button.
  5. Plug the TV back into the electrical outlet.
  6. Turn on the TV.
Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.
  1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
  2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.
This video shows troubleshooting steps to use when a "No signal" message appears.

In just bought new Toshiba regza 40" Lcd tv and auto tuned it, but the picture is terible , snowy and colours are not good, what to do...


Hello
First of all reset the TV. for that

press and hold the POWER button
on the TV control panel for 5 or more seconds to reset the TV.
Then connect the TV tt any source like outdoor areiel or cable box etc, select the appropriate input, and retune the TV. First of all, connect it to an external antenna, and set it to autotune.

You must configure the ANT/CABLE input source before

programming channels (-left-hand column).

If the ANT/CABLE input signal type is set to Cable, the

automatic channel programming process erases channels

that were previously programmed into the TV's memory.

If the ANT/CABLE input signal type is set to Antenna, the

automatic channel programming process adds newly found

channels to the existing set of programmed channels (and

does NOT erase channels that were previously

programmed into the TV's memory.) To remove an Antenna

source channel from the memory, you must manually delete

it.

To tune the TV to a channel not programmed in the channel

memory, you must use the Channel Number buttons on the

remote control.

Programming channels when the ANT/CABLE input is

configured for Cable will take substantially longer than when

the antenna input is configured for Antenna. This is normal;

however, once channel programming is finished, you should

not have to repeat the programming process again unless
your Cable TV service lineup changes significantly.
Find out the received channels are clear or not. If they are clear, your TV is perfect, and the input device you connects ot the TV is faulty. OK.
