SOURCE: TV & Tuner stays in Standby mode

Assuming you have tried changing batteries in your remote and any front panel power switch your set has, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.  What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.
 
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.  
 
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

Television will not stay on. Runs for 5 seconds then goes into standby mode.


Modern Flat Panel Televisions these days are really just computers inside. The Switch Mode power supply has the ability to sense faults & over current draw. So... there really isn't much the average person can do to fix an electronic problem.
The usual problem is overheating, bad connector problems & electrolytic capacitors leaking or popping. If you don't have the skills to open & look for problems then you will have to take it to a tv electronics guy.

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hi.

If you have no picture, no sound and the TV stays in standby it is not the remote sensor. That is the TV in protect mode (forced standby). The TV goes in forced standby when an internal problem is detected. Most Sony have buttons on the TV set. If problem is the IR sensor the TV Twill wake up if you press the channel buttons on the set. Try disconnecting power cord for ten minutes. If that does not work call the Sony support number listed in your user guide.

Regards.

This fault can be caused by low secondary supply voltages often caused by the value of capacitors becoming low and requiring replacements but you will have to have a technician.
