Toshiba 40RV525U green power light comes on but TV does not
Brand new unit, just had it for four days. Power on the TV and the green power light comes on but the unit is totally dead.
I assume that this unit just turned out to be a "lemon" and needs to be replaced since it's under warranty but was just wondering if anyone had a similar issue with an easy fix?
I'm probably just living in a dream world but thought I would just post the question anyway.

These blinks are fault indications, and are called blinking codes. From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. If you're sound in electronics, this will make the repair easy. If you wish to get more details about these blinking codes, check this link. Blinking codes to many brand TVs are described in detail. http://electronicshelponline.blogspot.com/

I want to know first if your TV have blinking lights red or green after the TV turns off?..if so,please count the blinking light to diagnose where the fault comes from..Or try to disconnect all connections of your TV such as DVD etc..then try again..
If the power supply and main board are both new..the possible problems are overheat or overload so please try the suggestions above..If not work please let me know if you have multimeter or if you know how to used it because we will proceed to voltage data..
My TV 40RV525U changing channels, menus itself for few months. my son tried to stop the channel scrolling by enter weird number into the channel to stop it scrolling such as 555, 777.. later, it turn on off by itself and unable to hold on a channel ( I use antenna) I call Toshiba customer service and they ask money $25 for troubleshooting but I denied since I do not want to waste money and time.
Now, I found how to fix it myself.
In my case, something was wrong with the signal comes from the button control on the left side of the TV. ======================== What I did ======================== unplug the power cord. Remove back cover. Look into the motherboard ( biggest green at the center).
I disconnect a connector on the motherboard come from the IR board that
receive the wireless signal control ( meaning the remote is disable). I turn on the TV, press on Menu button on the TV side. Menu is still scrolling.
I turn off TV, disconnect power cord and connect the IR connector back to the motherboard. I then disconnect the nearby connector that comes from the side control buttons.
Turn on the TV by remote, press menu button on the remote to check. The menu stays.
I use electric tape to seal off the connector and let it hanging there. Close the TV back panel
I have been watching TV for 3 nights without menus/channels scrolling. NO AVAILABLE red message when watching DVD is no longer existed.
Try resetting the TV by leaving it unplugged for an hour.
Plug it back in and check to see if it works normally.
If that doesn't work, rule out the Directv box by pressing the reset button near the access card. The box could be putting out a signal that doesn't have video or audio. If everything fails, have the tech man come back to check everything that he did before you use the warranty on the TV.
