Question about Sanyo Televison & Video
Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

You will have to have the set checked by someone to confirm this,
but most likely there is a problem with the TVs internal power supply.

If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.

Testimonial: "while we did not unplug the set, we let it sit for 2 days and we were able to turn it on by the remote & manually....does that still sound like P/S"
I have had the exact same problem with my 47LG70 after 13 months of use. I changed my remote control sensor but it did not help. Before you do that, try something simple which seems irrelevant. On this website, others have posted success by plugging in any standing set of headphones into the remote control or headphone jack on the rear TV panel. This solved my problem. So I proceeded to thoroughly dust all of the input/output component jacks on the rear and side of the TV with an air-can. This solved my problem and I do not need to have the headphones plugged in. So try these two things before changing the sensor.

SOURCE: how do I turn on
With the TV still in standby mode open the front panel tray by pushing on the triangle that is marked there. Then push the third or the fourth button. See diagram below (buttons framed in blue). The TV should come out of standby and operate.
These buttons are also used for going up or down the channels - press and the TV will cycle up or down each time. You can also use the second button marked F on the TV front panel to cycle sequentially through volume and other menus then adjust these up or down by using the buttons framed in blue.
See diagram below. Thanks for using FixYa and please remember to leave a vote for the solution.
