Loss of sound + loss of video = failed/failing main power supply.
Without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.

Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.

If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

How much does picture tube for 42 inch flat screen Sanyo TV cost


There is no picture tube in a modern flat screen TV.
And unless it's physically broken, it's usually something else that has failed and not the screen.
A picture tube is a CRT (cathode ray tube) that sends electrons from the back to the front to light up different color phosphorous dots.
A modern flat screen TV on the other hand is LCD (liquid crystal display) that turns on and off to allow backlighting through multi colored filters. (LED TV also uses a LCD screen, the only difference is the backlighting is LED and not fluorescent lamps.)

My 46 inch Sanyo flat screen turns on and right off again


Might be worth it if it cost over 500.00 dollars, I had a simular problem with a Yamaha HTR receiver... the cause was the power adapter/converter was overheating... so it sounds like something along those lines... It cost me 129.00 dollars to fix my receiver so I would say 100.00 dollars or less... I saw a 42" LCD at the local electronic's store selling New ones for about 400.00 now..
