Question about Standard (CRT) Televisions
I have a sanyo DS32225 TV that wont power up. House was hit by lightning. Came thru antenna cable. TV won't power up at all. Main fuse in TV is good. Any ideas before sending to shop or trashing TV?
SOURCE: TV was struck by lightning
If it was struck by lightning, the surge would completely fry the insides of your TV. Your TV probably won't work anymore and you may have to consider replacing it. Some TVs have accident warranties so something like this could be protected, but if not, you will have to purchase a new one.

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.

If the set turns on for a while, then shuts down, there is a problem internally that is being detected. The set has a num,ber of error detection circuits that will cause that shutdown to prevent further damage, You can try a "reset" if you like, but I doubt it will help. The easiest way to do this is to unplug the set for at least an hour. More than likely, the set has a number of poor solder connections and possibly defective parts. If you can solder, try resoldering any connections on the board that appear to be grainy or have rings. Update this with your results.
