Does anyone knows of any online guide that shows you how to replace a blown fuse for the tv?
I have a Sony (27") KV27V15, my nephew was playing with the power button, switching it on and off, now it doesn't even power on.
I'm completely clueless when it comes to electronic repairs, don't even know how to solder or what a fuse looks like.
Taking it to a repair shop is out of the question, this thing weighs a ton.

no better way to execute an early death... Each time you turn on/off electronic equipment... The electronics are flooded with energy in different ways. That's the time most systems go bingo...components are stressed to their limits. (some people feel it's just better to leave them on all the time, and there's some evidence to support that) I doubt you're dealing with a simple fuse here...
If it had a user replaceable fuse, you would have mentioned it. The other fuses are deep inside and should only be replaced by someone who knows the risks. But again.. I doubt this is a simple fuse problem, sounds like the repeated power up/down has taken out a balanced circuit. You're looking at a price high enough to entertain a new set.

If you don't know anything about electronics, you should not be messing with that tv. There is enough stored electricity in there to kill you even though the tv is unplugged. There are technicians who do house calls. Might not be cheaper but you're life is more valuable than what you will be paying the guy.

professionals have a device that literally "zaps" all the power out of the caps and such so they can work on it. (makes a big flash and a loud pop)
capacitors and such can hold a charge for up to or longer than a month even after unplugged. Ive personally seen someone get fuked up after playing inside a computer power supply.

Ive personally seen someone get fuked up after playing inside a computer power supply.I had a capacitor that would hold the 15K volts of a TV flyback... I use to charge it and let it sit on the mantle and tell visitors to not touch... I leave the room for two seconds and I hear a yelp... hear the cap rolling on the floor :) It would hold this charge for weeks!
