Hello, I'm Shahid and will be happy to assist you.

Please unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and again press volume down and input buttons on TV at same time to turn On the TV.

Does it stay On with letter K or switches Off after some time?

Please reply back to proceed further.

Thanks.

K shows up for 3-10 sec then powers off with the 2 flashing lights again .
Expert:  Shahid replied 1 year ago.

OK, there are two suspected things, either backlight inverter section on power supply board OR lamps inside LCD screen is defective. Swapping the power supply board in TV will help to see if it helps to resolve the problem or we are looking at bad LCD panel which would be an expensive repair if replacement LCD panel still available with Sharp parts in area.

I trust my input will help you out. Please feel free to respond if you have any additional questions.

Please check following two links for images taken from related service manual about how to enter in service mode and how to reset lamp error in service mode list.Please note that strictly follow the instructions written on those pages and do not change any other option in that list except the lamp error marked with arrow.
Any wrong setting could cause more damage that might end up at main board replacement.http://i.imgur.com/UA6ex5e.jpghttp://i.imgur.com/DrRpjKq.jpgI trust my input will help you out. Please feel free to respond if you have any additional questions.

Expert:  Shahid replied 1 year ago.

TV should stay On to perform those settings in service menu of TV that is why I asked if TV stays On with letter K, if TV switches Off after few seconds then there is no way to go into menu and it is hardware failure in TV which switch it Off.

Expert:  Shahid replied 1 year ago.

Required power supply board part number is ***** (DPS-222BP,(###) ###-#### ***** can be used to search/google to get price and stock info to order it if you wish to replace it by yourself in TV.

Customer: replied 1 year ago.
does it require soldering or is it just plug and play
Expert:  Shahid replied 1 year ago.

Its plug and play work, no soldering is required. Remove screws around the back panel of TV and take off back cover of TV then remove fixing screws of power supply board, unplug connectors and take out old board, put new power board, tight the screws, replug connectors. Job is done.

HARD TO FIND THE POWER SUPPLY BOARD LOOKS LIKE A LOT OF PEOPLE ONLINE ARE SOLD OUT OR I HAVE TO WAIT 2-3 WEEKS TO SEE IF THEY GET THAT PART IN... CAN THE 60 INCH SHARP SAME TV LC-60LE65OU BOARD WORK I HAVE A CRACK IN THIS SCREEN OR IS THERE ANYWAY TO BYPASS THE POWER BOARD AND DO A TEMP FIX TO THE BOARD
Expert:  Shahid replied 1 year ago.

Sorry to hear that, it seems you need to wait and keep checking ebay or amazon to see if some one sale it in coming days. I'm afraid LC-60LE65OU has different power supply board and it will not work in LC-70LE632U and there is no other way around to bypass the power board as it provides volts to backlight lamps inside screen.

Thanks.

is there a diagram on how to remove old board thanks
Expert:  Shahid replied 1 year ago.

Board removing is easy if you take off back cover of TV after removing approx 30-32 screws around the back panel of TV. Do you need exploded views off of service manual if having trouble to take off back cover?

Thanks.
