I have an older SanyoStandard TV, and an older big screen JVC I do not know model or product numbers. Both sets have worked fine for years the JVC began shutting down as soon as I turned it on yesterday, the Sanyo started it today.I use a DTV remote, hit tv and power, hear a click and the another immediate click, shutting down on their own.

Re: Standard TV-Auto shut down
TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
However, my experiance is to not put money into a TV that is over ten
years old. TVs stress out their electronic components worse than
almost any other electronic product. After 10 years, there are so
many parts that are ready to fail that your are probably wasting your
money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope ya fix it!

Your TV has no blue colour emisson. Red+Green = Yellow, Orange and so on. There is so many causes are there for this fault. As you say that your TV is an old one, it may be a transistorsed circuit board inside. Sometimes 2 or 3 Ics also will be there. You haven't given its model number to us. Without that we can't refer to your complaint with schematic diagram. You just give Fixya, its model number and other details and repost your complaint.
can you describe what type of problem the picture was having before it went out/ Also need the model number of your set. Please respond to this same post so the previous info is available when You post the model number.
Most likely there is a failure in the the scan amplifiers and or he power supply area. This will take some troubleshooting with a DVM and a scope as necessary. You will need the service manuals (schematics), and the necessary training and skills to follow up.
I think you should either look for another used set, or take the set in for an estimate. For someone who is not trained and equipped in TV service, this will be a big undertaking. There are also serious safety issues when trying to fix your own TV set. AS innocent as it looks, there are some high voltages employed.
