Turn on the power, green light turns on, then it shuts back off

This issue with losing picture and sound on your Viore TV after a certain amount of time can be caused by several things:
Overheating: If the TV is overheating, it may cause the TV to shut off to prevent further damage. This is usually caused by poor ventilation or dust buildup in the TV. Clean the dust out of the TV and ensure that it has proper ventilation.
Power supply issues: If the power supply is not functioning correctly, it can cause the TV to turn off and then back on. You can try checking the voltage readings at the power supply to determine if this is the issue.
Bad capacitors: Capacitors can go bad over time and cause the TV to shut off and then back on. You can check the capacitors on the TV's power supply board for any signs of swelling, leaking, or rust.
Main board issues: The main board of the TV could be malfunctioning, causing the TV to shut off and then back on. If this is the case, you may need to replace the main board.
If you're not comfortable with the above steps, it's best to contact a qualified repair technician for assistance.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

if powers on and has no video and no audio could be the main board, but first try this :

take a flashlight, turns on the tv and try to "see" the image while light up the flashlight against the screen , if you "see" something you have a bad back light inverter board.

below the posible parts number :

MAIN BOARD : Sharp 9JY0140CTJ05100
POWER SUPPLY/ BACK LIGHT : Sharp 9JY0940CTJ05000

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Trying installing a new power supply. This is the main problem with tv's with the issue. But if you just bought it I would try to get my money back from where I bought it from. Installing a power supply for a tv is not that hard at all.

There are two different things that i could think of that could be causing this problem. One being the main switch itself. try replacing that. and two the ps3 like almost everything does uses a disk based hdd and if it is dead or shorting out it will instantly turn off so you might want to check that.

hi Torgsrus.
PS3 Light sequence
The following pictures illustrate the CECHX0X model, however the light sequence is applicable to all PlayStation 3 models.

No lights are on:

When no lights are on, this means that the main power switch on the back of the ps3 is off or the PS3 is unplugged. When the main power switch is off (the '0' is pressed) and you will not be able to access any features of the PS3 system. To turn on the PS3 system, make sure the main power switch is on (the 'I' side is pressed down).

If the PS3 does not turn on:
· Make sure the power cord is not frayed or damaged
· Try using another power cord, if available
· Make sure the main power switch on the back of the PS3 system is turned on
· If you continue to have issues contact our Technical support.

Solid Red:


When the power status light is solid red, this means that the PS3 system is off (or in standby mode).
Standby, mode means the PlayStation 3 system is off, but is ready to be turned on by pressing the power button.

If the ps3 system will not turn on when you press the power button, this is an issue with the PS3 system and you will need to send your system in for service.

Solid Green:

When the power status light is solid green, this means that the PS3 is turned on.
You should be able to navigate the XMB, play games, access the Playstation store,etc.
To turn of the PS3, simply press and hold the power button for two or more seconds.
If the power status light is green ,and you are experiencing problems- have a look on our forums for troubleshooting.

Flashing Red:


When the power status light flashes red after using the PS3 system for 3 or more minutes and shuts off, the PS3 system has possibly overheated.

This may be caused by poor ventilation or the vents may be blocked.
If this happens:
· Check to see if the vents are blocked. If the vents are dusty, vacuum the vents to remove the dust.
· If the PS3 system is in an enclosed area like an entertainment area, move it to a more open area.
· Leave the ps3 system off for 30 minutes to let it cool down.
· If you continue to have issue, you may need to send the console in for service.

Flashing Green:


When the power status light flashed green, it means that the PS3 system is turning off. Please wait while the system turns off.

If the PS3 system does not shut down immediately, it may be trying to finish save data to the Hard Drive. If it is, do not turn the main power switch on the back off as it may cause data on your hard drive to be corrupted.

If the green light continues to flash green, the ps3 system maybe trying to write to the hard drive, shutting down or running programs. It may take longer to shut down depending on when you pressed the power button. If the green power light flashed for a very long time, you can try holding the power button down for 5 seconds, the console will beep and should turn off. Then try to restart the PS3 system.
Flashing Green, Yellow and Red:


When the power status light goes from green, to yellow, to green, then to a flashing red, this means that they may be an issue with an internal part with in the PS3 system. This may be caused by a variety of reasons and would need to be diagnosed by our support line.

When the PS3 power light flashes in this order, you can contact our Support Line for further assistance.

Solid Blue:

When the disk status light is remaining a solid blue, it means the disc is inside the PS3 system. If you wish to eject the disc, hold down the eject button for 2 seconds and the blue disc status light will flash indicating the PS3 system is attempting to eject the disc . (NB: the power indicator light will always be a solid green).

If the disc is inserted into the ps3 system, but does not show up on the xmb or will not play, this may indicate an issue with the reader- check our guide Discs are not loading in my PlayStation 3? for further troubleshooting.

Flashing Blue:


When the disc status light is flashing blue, it means a disc was just inserted into the ps3 system or a disc is trying to eject from the ps3 system. Depending on when you pressed the eject button, it may take longer for the disc to eject. (NB: the power light will always be a solid green)
If the light constantly flashes blue, it may be an issue with the disk being stuck in the system. If this happens there is no way to remove the disc yourself if you are using an orginal 60GB PlayStation.

sir i guess this is a power supply issue u should change ur the power supply box that u ve inside ur desktop

You have a power supply fault or one of the drive boards that drive the plasma screen is loading down the power supply. This power supply may be part of the entire main board. Good Luck
