Sound goes off after 15 Min


Assuming it is not hardware but soft settings...
1) Check and make sure that your TV does not have the timer set.
The Timer feature allows you to set a day and time for the TV to turn on automatically and the device and channel to display when it switches on. If the TV is already on at the requested time, the TV automatically tunes to the channel you designated in the Timer menu.
When the Timer turns on the TV, the following message is displayed: "Press a button for the TV to stay on." Press any button on the remote control within five minutes if you wish the TV to remain on.
Note: The TV clock must be set before you can use the
Timer feature (see preceding page to set the clock).
On/Off
Press down arrow / up arrow to enable or disable the Timer.
2) If not working, try SYSTEM RESET. Press SYSTEM RESET button on the front panel with pointed object (e.g. straight paperclip). TV turns off, green LED flashes for about 1 minute. When it stops flashing turn the TV on again. All settings other than Parental Lock need to be set again using the manual.
3) TV RESET. If all else fails for soft error. Your manual describes this last resort for soft type error. It could be hardware problem needing more expertise.

Tv only stays on few min then sounds funny no picture. Turn tv off then back on ok for few min. Then same thing happens.


sounds like a fault with the logic board. that area controls the sound and picture. if it is it will need to be replaced. look for a chip on the logic board that may have a crack in it.

Have a Sony KP-65WV600, already replaced d board once, and replaced convergence ic's once also. Now as soon as I turn unit on, turns to red screen and shuts off, video that is, audio works ok, noticed...


Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)

The tv screem on my ilo 32


The main power supply will be the first place to check. You should have at least the standby 5vdc, which is used for the main board, when the power switch is activated, the main board will send out the signal to turn on the main power supply sections to power up the rest of the set. Look for simple thing like blown fuse or bad capacitors. Learn about what bad capacitors can do.

When i turn on y Vizio LCD TV theres a blue screen that says no


Your TV is probably in RGB mode which means its looking for a computer signal. Plug a computer into your TV and then it will stay on. Then you can change it back to TV mode.

T.v. will not stay on


Power on your TV and press the INPUT button on the side of the TV repeatedly and rapidly until you can change it to a different input, such as AV.

If this does not work. Try this: With the TV off, press and hold the input button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. Let me know if either of these work.
