If it's totally dead then it's a power board, not too expensive, if it's showing some lights on the front blinking, then it could be another problem

Emerson tv....won't turn on...stand by light won't go off


Not making it on or out of standby---first place to look is the power supply for signs of damage or puffed up filter caps there.

** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).• Unplug the TV for two minutes and then plug it back in. Turn the TV on and try again.TV turns off unexpectedly • Sleep timer might have been activated. Go to page 24 for instructions.• KidPass might have been activated. Go to page 21 for instructions.• Wake-Up timer turned on the TV and no remote or front panel buttons were pressed for two hours.• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then

Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will helpout ......

My tv keeps clicking and won,t turn on


It is very possible that the power supply may have gone out. Which unfortunately is common on many newer tv's and other appliances. You can use a multi-tester or voltage tester to see if there is any power coming out of the power supply.
