First check the power source to be sure the outlet you are using has power.

SOURCE: Sceptre power supply short circuit

I have the same problem. TV was JUST out of warranty. Sceptre part number is X37SV-Naga and the cost - $285.00 plus $20 shipping. Non-refundable, no returnable.

The TV is of course going to de-solder the board within a year again, so either a good heat sing on both thermistors is in order OR a law suit against Sceptre is in order for putting us a risk of fire.

SOURCE: My Sanyo DP32648 was plugged into a surge

If you look at the power supply board as shown in the picture: http://assets.shopjimmy.com/media/catalog/product/cache/1/image/5e06319eda06f020e43594a9c230972d/s/j/sjdps153ap1a.jpg

There is a main fuse on the top left of the board covered by black shrink tubing, SLO-BLO 4A 250V. Check it out to see if it is blown.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

SOURCE: LG 32LH2000 My TV was turned of last night in the

most LG have a "vacation switch" on the bottom right hand side of the set very near that standby light.

it is placed poorly, where you can accidently click when grabbing the TV to move it or swivel it.

it is a toggle switch, a "master power" switch.

you may have bumped it to the off position. flip the switch, your standby light will come back on.

Hello
If cable box converter has damaged, there is no question about the main board of your TV. It has been damaged. Before replacing it, you have to check the power supply board also. If the TV has been pluged to power supply, surely there will be fault to it also. We can't predict the exact fault occurs during a lightning, because Trillions of volts are passes nearby. You have connected the TV with cable connection and to the home power supply too.
Just replace the main board first. If it does not hel you, replace the power board too. I hereby send picture of both boards.

Model dp46841 sanyo 47 inch tv won't power up


Likely a power board issue. Check that capacitors are OK in the power board, and if blown then replace with exact parts. This is a $10 fix, but if it does not work after than then cost go up like replacing the power board completely.

I have a 47 inch sanyo. model# dp46848. A transformer blew in a lightning storm and now the tv will not power on. The power light will come on for 5-10 seconds and then shut off. The tv was on a surge...


But, was the cable/satellite feed protected? Lightning can come in from anywhere, not just the power line. The bad thing about the way cable and satellite installers ground things is, they ground to the same grounding system that the house does, which can backfeed the surge through the entire house - it shouldn't, but it can.

I would, however, contact the maker of the surge strip and attempt to file a damage claim. They all come with a liability warranty of some sort.

Sanyo DSs31820 dead after lightning storm. Is there a master reset?


A lightning storm will destroy a TV in many cases. I have repaired very few, with this problem. I would certainly find a new TV, if this is the case for sure. Thanks for asking!

Lightning


Power hits are very difficult to recover from primarily because odd things can happen. Usually the standby transformer or power supply takes the largest hit. With no symptoms to go on, it is difficult to provide a diagnosis remotely. If you have any electronics experience, start by looking for the standby 5V inside the set. If that does not exist, start with getting that portion to work. After that, hopefully the set will attempt to start and we can continue from there.

Sanyo 21" t.v. will not power


I would check store and see if will take back, my not want to say it was storm. Just don't know first. If will not take back or exchange then open and look for open fuse, or open resistor in Power Supply.
