Question about Televison & Video
Try checking these:
Electrolytic capacitors in main power supply or elsewhere - see if any have an inflated or blown out top - replace these. Also see if any of them has a bad solder contact on the pins, if so, resolder the pins.
Other burnt out components like resistors, diodes, transistors (if they were heating up, you should notice the circuit board around them has become darker from heat). Check solder connections on these, too, and resolder if necessary.
See if any connectors have oxydized pins, if so, clean with some fine sandpaper (some might be a bit difficult to access, though). Again, see if there is a desoldered/damaged solder contact on any of the pins, resolder if necessary.
Now, these are just some of the possibilities, and if none of the above does the trick, then your TV just might need some professional servicing.
Anyway, hope you can fix it yourself...
