    I would highly recommend you do all the usual checks: fuse, shorted FETs, capacitors, etc. before consulting a schematic.

    The best (and possibly only way) to obtain a schematic would be to find an authorized sevice station that would be kind enough to let you copy theirs. Some manufacturers will still sell them at highly inflated prices but in most cases they're put out in large packages, often on DVD, and only provided to their authorized servicers.

    Over 1,000,000 different TVs have been built over the years and in just about as many different ways. They're also rarely designed to be serviced at all since they're full of proprietary components, in most cases the only solution is by replacing entire PC Boards once you've diagnosed it to a particular board being the fault.

    Gone are the days when things could actually be repaired, the electronics consumer appliance market has pretty much become a throw-away situation.
