I had the same problem. I work for a mother board manufacturer w/offices in New Jersey and brought mine into our engineering lab after Samsung told me tough luck. Anyway, one of my engineers fixed it in 10 minutes. Essentially, he replaced the 1000uF capacitors on the power supply board with 2 cent capacitors instead of the 1 cent capacitors that had blown out on the CHEAP SAMSUNG POWER SUPPLY BOARD. You can tell the caps are blown via visual inspection. The top of the cap should be perfectly flat and a blown cap will be convex on top. Unfortunately, there are also 2500 uF caps by the same cheap manufacturer on the board as well and we don't stock that value for our products. According to my engineer, those will most likely blow next since he replaced the others with better caps, but I'm getting samples of those and will replace them shortly. After that this piece of junk should last me at least another 2 yrs! It's been working for about 3 weeks now w/no problems. Hope this helps.

Sony KDL 46HX820 turns on, then off and red light blinks four times.


Re: Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

My LG TV red light won't turn on. although the plug fuse and the remote OK


Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

I was watching my tv when my son hit the reset button on my surge protector..now my tv will not turn on. Any ideas?


Turn everything off, the tv the power and make sure the button is not active at the moment. Some surge protectors do come with a fuse but when you turn the surge protector back on itself make sure it is recieving power, there is usually a red light on the switch while recieving power. Then try again once you know there is power to it.

An electrical pulse from the thunderstorm has affected your TV. (Was it on a surge protector?)

There is a small possibility that it will come back.

Unplug the television and let it sit for an hour or more and then re-plug it.

If you need to get a new TV, also get a good surge protector such as Panamax.

Power Outage Problems Sony Bravia 32" LCD TV


try cycling the power (unplug 2 minutes) and plug in and wait 30 seconds and turn back on. if this doesn't work, could have been a surge, your protector should have saved it, but could have been through cable or something. surge protectors will guarantee no damage for several years, check with the manufacturer maybe they'll cover the repair.

Sharp aquos 42 won't turn on even though the green light is on, turns on for a second then goes black, but green light is still on, if you turn off and on for about 20 times it eventually stays on


Call 877-332-7867 and allow the customer service representative to create a case file for you. Next ask to be walked through an INIT/factory reset. You will need two people unless your tv is plugged into a surge protector that can be switched on and off with your foot because the first step will be to unplug the television or switch off the surge protector it is connected to. The next step is to hold down two of the buttons on the panel while plugging the unit back in/switching tbe surge protector back on with your foot.
