After a thunderstorm, blew. trying to find the fuse and circuit breaker
It is at its main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit; before replacing a fuse; if found blown out. 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.

The board where the a/c power cord go into it.That ur power supply board,that board is dead,replaced this board.U will have ur power back.Tries websites like Shopjimmy.com,Ebay.com to buy a reburbish power supply board for the replcement.

Hello
As the set reports, the strength of the digital signal it gets may be weak. An other possibility is the fault with its digital tuner itself. Check the digital signas strength first. You can contact your cable provider, and ask them to check the signal strength at your premises's cable end. If it found satisfactory, there is no other way than replacing the digital tuner of your TV.
It is a skilled work, and should be done either by any expereinced serivce technician or by the authorised service center for Sanyo at your town. OK.

ISSUES:
1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.
Answers to issues:
1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.
2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.
Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.
What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.
3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.
4. Safety first--no TV set is worth getting injured or even killed over.
