Hi,

There are a couple of things that could cause this, unfortunately there is no reset for this televisions and it will have an internal failure at this point. I will try to explain the possibilities the best I can, assuming you have checked to ensure the outlet is working and the cord is firmly plugged in on both ends.
If the set is completely dead then there is a possibility that the AC fuse is blown, but that would be rare unless you had a power fluctuation of some sort, this type of replacement normally runs $100-$125 in your home....if it not he fuse then....

First you could have a failure in the power supply, we have seen some capacitors fail in your model and cause funky problems like this. If this is the case you could be looking at somewhere around $175-$200 to fix the set. IF the power supply had to be replaced you could be looking at $350

Next could be the main board, this would not be good news because you could be looking at $400-$500 for the repair (I know this is up there in the price range and most likely getting over the cost of a new set)

Lastly you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set. The panel in your TV is about $800 just for the part.

Any of these could cause your problem, but it will require troubleshooting to determine the exact cause of your problem. If you have experience, and test equipment and would like to attempt some troubleshooting I will be happy to assist you, however if you do not have equipment or experience then you would need a repairman at this time to get an exact diagnosis. I am sorry that I don't have a quick fix or easy answer for you on this one, it is definitely an internal failure.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Better check with a test light for power to the small wire that goes to the starter from the key switch. If no power need to check for a neutral safety switch or fuse. Or the starter you got is bad. Alternator will not cause not to crank over

If you have no fuel pressure at the engine when key is on, the pump is not coming on. Check fuel pump fuse, check fuel pump relay (relay should click when key turned to on-put finger lightly on it and feel for click when someone turns key to on). If no click, signal from computer may be lost, ground for relay may be lost, or relay may be bad. If it clicks, wiring from relay to pump may have failed, or the relay's main power source may not be there at relay-find the fuse link or maxi-fuse that powers that relay. One terminal at relay should be hot at all times-can check for that with a test light.
If pump is working and you do have fuel pressure, you will need to check injector circuit. Post back if questions, or need further help.

Visio VP504 fhdtv10a - When I plug it in, it has an amber logo light and makes a click noise (like a relay). When I press the power button nothing happens.


These are problems gradually developed in TV over the years. You may have to look for any dry solder, change the capacitors that look 'puffy' and try.

KDL 40S4100 relay clicks and nothing, should the standby light be on? Vince


The relay just puts the main power transistor and its transformer under power, if the defect is large enough to damage either of them the power source will be completely shut down and the status light will be off.
You need to open the tv and test the power circuit, starting with the mains rectifier and its high tension filtering capacitors.

Sharp LC-45D40U Won't Power On! Need Help!


If doesn't give error code most probably is something wrong with 5 and 3.3 volts lines. Check first the power supply and try to start the tv with all connectors removed. Let only the one between main pcb and power supply. Look for shorted voltages lines.
