No power to tv

I turned on the tv yesterday only to get a single slight popping sound and then the power to the tv went off. I unplugged the unit for 30 minutes and then replugged it back in to no avail. Is there a fuse that could have shorted out and where would it be located to be replaced. Thank you

Re: No power to tv

Sometimes, during a thunderstorm a computer or television or gaming console can make a popping noise and be completely fried. And other times it can be protected through a surge protector and no lightning strike it and it still makes a popping noise. I have found out both the hard way. Every so often a television (like in your example) will fry its "motherboard" and the electrical components will be shot. Unfortunately, unless you can find a wiring manual, the best thing in most cases is to just replace the television. If you find a wiring manual check to see if a wire is melted inside the components deck on the back, but please please please and I can't stress it enough, 1) consult your owner's manual or warranty to make sure you're not violating it, thus making your TV a huge paperweight, and 2) be EXTREMELY careful. Wiring is not something any person should attempt without basic knowledge of electronics. I would recommend an electrician friend or someone who knows wiring to look at it, that is if you don't.

I tried turning my Philips Flat Tv by pressing the power button on the side and a loud pop-noise went off and the tv havent turned on since, all I see is a red blinking lite in the left bottom side of the...

Unplug your unit for 5 minutes and plug it back in - turn it on - if problem persists then your TV's power supply is finished.

No it is not your circuit breaker or fuse otherwise you would not get ANY power to your outlet and would not see a blinking light. It sounds like a bad power supply.

This is may cost you a lot of money to repair - I hope your TV is under warranty.

Tv plays sound but no picture or any signs of backlight

This sound is a capcitor pop and this could be in the power supply unit itself. The glass could be a fuse that took the brunt from the capcitor pop.

1. Unplug the unit and do not plug it in.
2. if its under warrenty take it in please!
3. if its not under warrenty and you know eletronics verify what cap popped and replace that and the fuse.
4. if you do not know about eletronics this work would cost you around $150 for the wrok done.

Good luck I hope this information helps you!!

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to
