Volume problem

I would try going into the settings and seeing if any Audio Limitations are set.

Sometimes this cannot be controlled due to the devices connected to the TV set.

Also try to cold boot the TV by unplugging for 5/10 secs and plugging it back it.

When I turn on the tv all i get is the welcome screen, and it will not go any futher,there is green light flashing in front of the tv. and it will not turn off with the remote, i have to unplug it.

Hi Andre,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.

Well my mom was watching tv and it just shut off so then my mom turned it back on thinking she might have hit the power button accidentally. But when she turns it on it started blinking the green light for...

The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

TV won"t stay on turns off in 3 seconds WS 55807

Do the self check when power light goes off.

On front of set press and hold both the menu and input buttons for 5 seconds or longer and release both buttons.

Power light will blink a error code like: 2 blinks, 2 blinks, a pause and repeat about 4 more times.

Let me know what error code you find and I will tell you what it means.

If this information told you something rate this solution as very helpful as I do this here for free.

Tv does not stay on.

Your most likely having a problem with your power supply. I would say check the capacitors for obvious signs of swelling and all fuses first. Next I would check your low voltage regulators.Have you tried pushing the menu and imput buttons together and holding them for 5 seconds to access the self diagnosis feature? If you cant initiate the self diagnosis feature its probaly the capacitors or Regulators.
