Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. This should fix the problem. Check to see if your TV is still under warranty first though.

Heard a pop, tv went off, and it won't power up


Power supply in most cases and a lot of the time the part is under a heat sink where you cannot see it.

You might have more help if you posted the question again with the exact brand and model number.......

I was watching my Hitachi 42hdm12 and heard a pop and now the picture won't show up or sound or anything?


A pop is usually a power surge and you blew a board. If you take the tv apart, if this is it, it will be evident by the burn marks. You could have burned out the internal power supply as well.

Popping noise and now won't power up. Red and green indicator lights blink on front of tv.


start by checking the power supply in the set and if not able to do that consider taking it to a shop for an estimate.

Samsung plasma tv made a really loud pop and the screen and sound do not work but the red power light won't come off unless the tv is unplugged what happened?


The main power supply regulator board has the fault. Check if any electrolytic capcitor/s has bursted out. Replace them if any. If this do not help you. repalce the board as card basis.
Replacing it as card basis is fine, rather than making 'surgery' to it.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...


3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

AOC Envision L32w761 TV. Lightning strike. Now nothing. Power light won't come on. Checked power to the Power Supply board and have it fine. Replaced TV and everything in the system looks OK. Bad TV...


If you are certain you have a lightning surge, almost anything can take down your TV. First check the obvious, do you have power coming out of the wall. Is the surge protector good, if you used one? If you have answered yes to the these questions, you may have acquired a power surge in your TV. You may not find it in your TV. As I have said it may be anywhere in the TV. You will need to take this TV to an authorized service center. It would be difficult for anyone out side a technician to find the problem. Thanks for asking and show all hands of support!

I have a 1 1/2 year old Panasonic TC-P42U1 plasma tv. While watching a show, it suddenly shut off and won't come back on. What do you think caused this and how can i fix it? Thanks.


Try unplugging it completely for 30 seconds to 1 minute. Plug it back in. If it still won't come on, it's likely taken a power surge and popped a fuse or power supply, which means a trip to the service center.
