Question about Funai F4819T 19" TV
I recently moved my apartment around. There was work being done to it. The television worked fine as I was living temporarily in another apartment. I moved back into my original space and now it shuts off after being turned on. This is frustrating me. What is the real cause of this?
The television is going into high voltage shut-down. Best guess, either a faulty voltage regulator, bad cap, or both. Be careful when working inside a television due to high voltages that are present even when television has been off and unplugged for days. Good luck.

This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.
Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below a links for tips on poor start ups.
It is possible you need to check the soldering at the deflection circuits/audio sections as the picture/sound comes back due loose joints which contacts when the circuit is lifted. Solder all the suspected joints with a good light to assist and make sure there are not solder bridges.
